We are looking at the option of buying couple to use for makeup water to our DI water system. I am hesitant to use these units but because of budgetary reasons I am entertaining them as an option. The questions I have about the units are as follows. How is their longevity? What types of repairs have you needed to make and at what age of the unit? What have you operating costs been for these units and their supporting systems? How many units are you running and what size system do you have? Are you using it for point of use or as a makeup unit? Would you buy one again and if not, what would you move to and why? Add any pertinent data please. Deon D.

I would purchase wafer dicing blades which had an angled edge to them instead of being flat. I would get these blades from Thermoccarbon in Casselberry, FL. You could ask them if they'd be willing to sell you some 45 degree'd blades; my guess is they make these.

Generally works well, doesn't have any alignment capability but has some tooling so you can align in a Karl Suss mask aligner then transfer to the bonder. If I could improve it I would make it easier for doing stacks of three wafers - this is an option for Karl Suss but expensive - we can sort of get round it with conducting copper tape. Support has been OK but seems to need something almost every time it is used! Over the ast year has probably been used 20 times and just on the one project.

(Listed in our cleanroom equipment website: https://cnm2.ucdavis.edu/equipment ). We are very happy with the tools, and the service & support from EVG have been great. We purchased them in 2016 after a few years of demo testing at their facilities (paid fees to get custom bonding done and in some cases sent my students there for various testing). At the time of purchase, I carefully looked into various other vendors? tools, and we have been happy with our decision. My students have been doing hydrophilic bonding between dissimilar materials (GaAs-Si, AlGaAs-Si, InP-Si, LiNbO3-Si) as well as Si-Si and SiO2-SiO2. Some others have done anodic bonding (I try to avoid sodium for my projects so I don?t do anodic bonding). I don?t allow polymers in the wafer bonding chamber, so no polymer bonding, but we do transfer printing with and without resin in another EVG tool. Let me know if you need more info.

I have a student that would like to sputter Ti. I have a Ti target, but it doesn't have a backing. All of my other targets have backings. It seems logical that if I want to use a target on a gun with a MagKeeper I would need a backing (pictured is my Al target with a backing). I asked our Lesker sales rep and his response was to use the Ti target without the backing. I asked if the target will slide off of the gun. His response was no. Does this make sense? Does anyone have experience with sputtering Ti in a Lesker tool?

Talking to our equipment engineer for the ALDs, he identified three major problem areas for the manual loader, all of which can cause dropped plates. One, the leaf springs break from fatigue. Two, the bearing assembly that holds the arm in place has two bearings supported in single shear with steel pins that can bend and allow the arm to droop. Three, the pins may loosen up from thermal cycling through contact with the hot plate. I'm happy to chat more offline if you have any questions. The company also has helpful support through ALDSUPPORT at veeco.com for replacement parts and general inquiries.

Are you supposed to include any N2 purge from the pump in those numbers. For example, an Edwards iQDP80 will typically have a ~ 50SLM purge, so in the case of the 3 CFM purge requirement, it's only an additional 30-40 SLM (1-1.5 CFM). All that N2 is going to flow through into the Callisto. Also, if you are abating a process that requires passivation of the abatement column, that does often require extra N2, so perhaps that where the higher levels are coming from. To be clear, that should process dependent and not always necessary to the best of my knowledge. My experience with dry abatement using granulate (I believe this how Callisto work) is that there is also an upper limit on N2 as well where too much Nitrogen reduces the residence time of the effluent within the cannister, making the abatement less effective. There are other options for dry abatement if you are looking for something with lower N2 consumption.

We went through this process when our contract with Cintas came up for renewal about 2 years ago. In terms of laundry quality we had no particular issues with that, but we did have issues with laundry going missing, laundry from a different group getting sent to us, poor communication, a steady creep in invoiced amounts, and at one point they added a different department here to our billing without confirming with us. To be fair, the managers of their cleanroom division have been promptly communicative and have always tried to work with us to fix the problem of the month. Communication wise I?d probably still prefer them. And regardless, all of that would still be better that Aramark who never even returned our requests for quotes and the like. Currently we are in an agreement with Prudential Cleanroom Services. Pricing and laundry quality has been great. I?ve got a couple of items that belong to someone else mixed in, but not too bad. Our biggest complaint with them has been that there was a major disagreement at the start of the contract about what we thought we ordered and what the paperwork said - at least part of that was on us - and it has been nearly impossible to get responses from the sales lead since the original contact negotiations, even if what I want to talk about is potentially giving them more money. I feel like they may have grown too quickly, at least their west coast arm, and are struggling to manage that. But that?s a feeling because no one will speak with me enough to confirm or deny it. I know some places do their own laundry at this point. That might be best if you have the space and infrastructure. At the end of the day, it really seems like they all have their problems, sharing many of the same problems even, and that there is no ?easy to work with? option. At this point I essentially feel like I need to micromanage the process regardless of who is doing the service. I?ll review my documents and comment on pricing to you separately. Best of luck. Really curious if this sentiment is general across this list or just us? -N.

This is a big change that ensures there is no cross contamination with other firms garments. Invoice from 8/11/2023 was $444.22, which is an every other week cleaning. If big semi is having their suits cleaned every other, why do we need it every week? Here is the break down from on Prudential Cleaning Service Invoice Quantity of Coveralls 169 Quantity of Boots 388 Quantity of Hoods 238 Frocks 8 Total 808 Cost $444.11 Twice a month charge to pay off initial suit purchase $500 Total cost $944.11 Maximum cleaning per year 26. So maximum cost for cleaning on a yearly basis is and we own our garments at the end $24,546.86 On Tue, Sep 19, 2023 at 10:23?PM Dennis Schweiger wrote: > Good afternoon all, > > Here at the University of Michigan/LNF we've been using launderable > garments for many years (Cintas is the provider).

We went through this process when our contract with Cintas came up for renewal about 2 years ago. In terms of laundry quality we had no particular issues with that, but we did have issues with laundry going missing, laundry from a different group getting sent to us, poor communication, a steady creep in invoiced amounts, and at one point they added a different department here to our billing without confirming with us. To be fair, the managers of their cleanroom division have been promptly communicative and have always tried to work with us to fix the problem of the month. Communication wise I?d probably still prefer them. And regardless, all of that would still be better that Aramark who never even returned our requests for quotes and the like. Currently we are in an agreement with Prudential Cleanroom Services. Pricing and laundry quality has been great. I?ve got a couple of items that belong to someone else mixed in, but not too bad. Our biggest complaint with them has been that there was a major disagreement at the start of the contract about what we thought we ordered and what the paperwork said - at least part of that was on us - and it has been nearly impossible to get responses from the sales lead since the original contact negotiations, even if what I want to talk about is potentially giving them more money. I feel like they may have grown too quickly, at least their west coast arm, and are struggling to manage that. But that?s a feeling because no one will speak with me enough to confirm or deny it. I know some places do their own laundry at this point. That might be best if you have the space and infrastructure. At the end of the day, it really seems like they all have their problems, sharing many of the same problems even, and that there is no ?easy to work with? option. At this point I essentially feel like I need to micromanage the process regardless of who is doing the service. I?ll review my documents and comment on pricing to you separately. Best of luck. Really curious if this sentiment is general across this list or just us? -N.

We suspect that it is related to the controller. We have noticed an issue with the lateral beam sweep coil current in the Temescal TemEbeam controller (EBC). When the controller is turned on, the lateral beam sweep starts out at a high current of ~3-4 amps and is unable to be lowered using the lateral/latitude sweep position controls. This high current appears in the negative (left) region of the sweep pattern display area. We have checked the leads from the sweep coils up to the end of the connector attached to the ?Sweeper Coils? terminal at the back of the controller, and no issues were found. We have also tried a full factory reset of the controller as well as unplugging/plugging in the power cable at the back, but the high current issue still remains. Any advise would be greatly appreciated. Sincerely, Alexey -- Alexey Kovalev Assistant in Research A302 NHMFL FSU 1800 E.

The gun has low hours on it and has plenty of life left. We are looking to get $50K but will entertain reasonable offers. *Detailed Specifications* *Imaging* - Resolution: - 5nm under optimal conditions at 15kV SEM mode - Magnification: - SEM: x100 (at WD 25mm) to x1,000,000 (at WD 8mm) - Low-Mag LM mode: x25 to x19,000 - Imaging Modes/Detectors: - SEI: secondary electron imaging - LM: Low-magnification mode - GB: Gentle-Beam mode - Applies negative voltage to the sample stage to increase effective acceleration without increasing beam acceleration (reducing charging). - LABE: Low-Angle Backscatter Electron detector - Inserts between the objective lens and the sample - Strong contrast between materials - LEI: Lower Electron Detector - Detector is lower on chamber, creating strong topographical contrast. - Accelerating Voltages: - SEM: 0.5 to 30kV - GB: 0.1 to 2.0kV - Beam Currents: 10-13 to 2x10-7 A *Mechanical* - Max Sample Size: 4-inch wafer - Stage movement: - max: 70 x 50mm - 4-inch wafer: limited to ~25x25mm movement area from wafer center. - Tilt: -5? to +70? - Rotation: 360? - Specimen holders : - Copper and XYZ Carbon tape available - 4-inch wafer with topside clips - 1-inch holder for 30?/90?, 45?/90? mounting with tape or clips. Electron detection: - *SEI*: in-lens secondary electron detector for high-resolution imaging. - r-filter to select electron energies to pass through to the SEI detector for image enhancement. - *LEI*: lower, in-chamber secondary electron detector for enhanced topographical contrast; very helpful with charging substrates. - *LABE*: insertable, in-chamber *l*ow-*a*ngle *b*ackscattered *e*lectron detector for atomic number imaging contrast - *Mixed*: can combine inputs from the 3 detectors above to get a more detailed overall image contrast. Imaging Modes: - *Gentle Beam*: substrate biasing up to -2kV for lower net beam voltages at the substrate. This effect directly reduces insulator charging issues when imaging. - *SEM*: regular, hi-resolution imaging mode (up to 1,000,000X mag) *LM*: low magnification (down to 25X mag) used for finding regions of interest on the substrate.

Few years back we had a similar problem with the controller. I had to trouble shoot the unit. I would describe the repair to you, First you need to measure the inductance of the deflection coil in the chamber. There should be two set of coils for beam deflection in say X & Y direction these coil should have some reasonable inductance say around 10 Ohms. Please note the DC resistance if a false indicator and don't use a DMM to measure the resistance. Once you are certain the deflection coils are not shorted out then try investigating the coil deflection unit. In principle this unit is essentially a two channel audio amplifier which is being driven by a two channel. In our case the final stage of the coil deflection amplifier was made up of an audio amplifier which had shorted out, in this case there is going to a constant DC signal being applied to the coil. I had to replace this amplifier and the part number for our design is LM3886T, in addition we also had to replace some freewheeling diode and the part number for that was RS3M-13-F or something equivalent. In case you are in doubt open the unit and share few pictures of the PCB.

Caution: External sender Hello All, We have an issue with the coil current for the e-beam evaporator and wondering if somebody had a similar problem in the past. We suspect that it is related to the controller. We have noticed an issue with the lateral beam sweep coil current in the Temescal TemEbeam controller (EBC). When the controller is turned on, the lateral beam sweep starts out at a high current of ~3-4 amps and is unable to be lowered using the lateral/latitude sweep position controls. This high current appears in the negative (left) region of the sweep pattern display area. We have checked the leads from the sweep coils up to the end of the connector attached to the ?Sweeper Coils? terminal at the back of the controller, and no issues were found. We have also tried a full factory reset of the controller as well as unplugging/plugging in the power cable at the back, but the high current issue still remains. Any advise would be greatly appreciated. Sincerely, Alexey -- Alexey Kovalev Assistant in Research A302 NHMFL FSU 1800 E.

It was never a good solution. We continually had item lost, damaged, mixed in with our returns and lost/damaged shipments. On top of that the manpower it took to manage the shipping deliveries and inventory moving around does not pay off. We ended up buying a quality top loader washer with a SS drum. We also ended up installing a small but effective RO on the water supply line, a bag sealer, properly sized bags, and a set of nice SS racks. We hang the cleanroom suites up to dry on the racking in the same space as our washer. Our washing machine is in a storage room which is within our clean room. As the garments a not porous there is little to no water, they dry quickly. We also bag them for storage till they are required for swap out. Our losses have gone to near zero and we feel there is a better product provided to our cleanroom users. As we already owned our garments it was a no brainier. Our lab assistants process the laundry in the evening. We were spending thousands just for laundry services a year. On top of that the loses, damages and shipping were all recouped in a matter of months. Granted you will need a little assistance from the staff but it is worth it. Hope this helps. Deon D.

We've had mostly good success, and our vendor has helped us to incorporate a simple suit modification to allow for better identification of individuals when they are in full garb.

Our machine is set up to use ambient temperature DI water (and CR-2 cleaner), but the unit is just an off-the-shelf machine that we got from one of the big box stores. It has a stainless steel drum, and our thought with the DI water is that as soon as the water hits the equipment, it's way less than DI, but still way cleaner than city water. It allows us to pretreat garments that might have gotten excessively soiled as part of a maintenance project. Our experience with Cintas is that they're not set up to do a Tide commercial for clean clothes, but we still want the additional support they provide in regard to a final clean, and the packaging. This has been a good conversational thread. I don't know if we'll change our practices, or vendor, but it has been a great discussion. Thanks to all who chimed in with their experiences, and input. This is truly a handy forum to have. Dennis Schweiger University of Michigan/LNF 734.647.2055 Ofc On Fri, Sep 22, 2023 at 12:26?PM Brian K.

At MIT.nano, we own our garments and send them out for laundry on our own schedule (currently, we pull everything weekly). We bought garments with RFID tags, which avoids having to hand-count. We scan full laundry bags on the way out and in, but are in the process of testing a full-room antenna setup that can eliminate the need for all manual efforts. The RFID tags allow us to see when shelves run low, and also how often people single-use garments and put into the hamper. RFID readers in the pregown area and back of the house allow us to track lifecycle and inventory. Why own? Because we own the garments, the contract and interaction with the laundry vendor (Prudential in our case) is much simpler and carries less misunderstandings. If vendor operations were to deteriorate, we can switch to another vendor without significant delays or costs. By owning, we also have no ?lost item? charges and confusion. For some vendors, my understanding is that if a rental item is not scanned in by the vendor within an expected time window, the vendor assumes it?s lost - and charges you for replacement. That?s problematic if you have a few items at the bottom of the bin, sitting there for months, until they get used. Not sure what happens when such items finally resurface -- and if the vendor reinstates the tag and refunds the replacement cost (I somehow doubt that). But even if they did, it would create confusion and frustration on the billing in the meantime. How many? Inventory ideally is 5x to 6x the weekly average, for us. A 3x multiplier is theoretically enough (1 set in use, 1 set in transfer, 1 set at laundry) - but that leaves no room for fluctuations or errors. It works for labs with constant usage. But with usage fluctuations, we found that at least 4x is necessary (we occasionally ran out even with 4x). Having 5-6x is ideal in our experience. Temporary shortages can occur when a bag is delayed or misrouted by the vendor (where it can take weeks for items to trickle back from whoever received them). The attached graph shows how, as we ramped up at MIT.nano, the weekly fluctuations also increased. Sufficient inventory allowed us to offer outreach / non-user events in January, where during one week we had 128 non-fab users work in the fab to build something (in multiple sessions; not all at once, obviously). Currently, based on laundry data, our ?worst? three week period utilized 615 suits, when on average we use about 130 user suits a week. That?s a 4.7x ratio. Thus, an inventory 5x the average weekly usage helps us avoid running out of stock. (In-house laundry would add flexibility to run on smaller inventory if one has reliable control on when/what items get washed) How often? There is a cost tradeoff between: storage, inventory, laundry. We evaluated sending out laundry at cadences other than weekly - to save on laundry costs. But it would require larger inventory: many users don?t work in the lab every single week. The increased inventory adds upfront cost, and the gowning room needs more storage. For our usage pattern, we decided weekly laundry was a better choice. The attached quantity vs frequency plot estimates this (based on actual data of when users run tools in the lab). Bi-weekly laundry would cut the number of annual items to wash, but only to about 61% (not down to 50%) - because of how/when users come to the lab. A side benefit is that weekly laundry is more predictable for users. Finally, giving users the choice to how long to leave their items hanging does not work for us, because most users are not sure when they will return to the lab. User-initiated laundry would end up taking up lots of space & inventory due to inactive users. Sharing Boots? In the very beginning, we had individual boots for each user clipped to the bottom of the bunnysuit. That became a gigantic mess, instantly. Even worse, some users clipped boots by the collar inside their suit, getting boots in contact with their hoods - not great for safety. We quickly switched to shared boots, stored in a boot rack. It works great, and we pull/wash these boots weekly. It also reduces the number of boots that need to be sent out for laundry each week. Other data..? Our users use about 1.2x the number of hoods than suits, because a small subset of users appears to replace their hoods them during the week (either due to personal preferences, or because they get soiled from heavy use). Our distribution of suit sizes is 7% small, 40% medium, 39% large, 13% 2-XL, 1% 3-XL. The ratio between medium and large has been constant throughout, while the user numbers grew. (note on quantities: a misrouted bag has a much larger impact on the S and 2XL items, because the relative impact of such a bag is high - so running larger ratios for small and 2XL is helpful) Best, -Jorg From: labnetwork On Behalf Of Dennis Schweiger Sent: Tuesday, September 19, 2023 1:59 PM To: Fab Network Subject: [labnetwork] launderable cleanroom clothing Good afternoon all, Here at the University of Michigan/LNF we've been using launderable garments for many years (Cintas is the provider). We've had mostly good success, and our vendor has helped us to incorporate a simple suit modification to allow for better identification of individuals when they are in full garb. As part of our due diligence for keeping costs under control, we'd be interested in comparing notes with other Universities that are also using an outside company to provide your laundry service. Currently our laundry costs run us about $52K/year and we're laundering roughly 500 pieces of clothing every week.

First let me say we had a Lydall Infinity chiller on a Plasmatherm system. It was ok. I still have it and it was repaired twice in 8 years. The company has been bought out by Boyde Corporation and they will still repair them in New Hampshire. Unfortunately they do not make these chillers anymore. They are local so it is still affordable to ship and repair. While it was out being repaired, I bought a Jalabo Presto chiller to replace it. It took some engineering to get it to communicate with the system but it is working really well. I have several SMC chillers and the ones that run on Galden are great. !0 years on both with no issues. The DI/distilled water chillers break down every 3 to 4 years it seems. To repair they need to be sent to Japan, a major pain. My recommendation is to call Boyde(781) 208-0094 Scott Jukubec and see if they can repair it. If you need to replace it, I recommend Julabo over SMC just because of price and serviceability.

Under the hood, there is a Google form that is connected to a Google Sheet. When a new entry is created (which is a new row in the Google Sheet), a free Google Sheet plugin triggers the creation of a PDF from a Google Doc template. We require signatures on this PDF via DocuSign. The signature panels (and other field information depending if they're internal or external) via DocuSign are setup manually and administered via our business admin. Since we've eliminated email, there is a good amount of tracking that is managed digitally via the Google Form (Google Sheet) and DocuSign. You can get an idea of the questions we ask on our form via our onboarding link: https://www.nano.upenn.edu/working-with-us/getting-started/ When the signatures (other info acquisition) are completed, our business admin goes into NEMO-CE to create the users, projects, etc. The instructions to do so are part of the document so in case our process changes, it is documented accordingly. How quickly a new gets trained depends on how quickly signatures are obtained from the PI, grants manager and/or user and the availability of one of our three cores for training from which they are requesting training.

Cleanroom Access training can only be requested after all the paperwork is ready and account has been set up in our system. Usually we request two user forms which can be submitted by emails. It probably only needs half an hour to set up an account for each new user if all the paperwork is ready. For the orientation, it includes two parts: presentation and cleanroom in-person walkthrough. Presentation can be done remotely or in-person, introducing the cleanroom, instruments, benches, policies etc. Currently we prefer the in-person way even the zoom meeting allows the interaction for the presentation. It will takes about 1.5 hrs. In-person walkthrough also takes about 1.5 hrs. No matter which part, it has to be performed by one staff. The total users in one session maxi out about 4 persons. Even we spend several hours on each new user, some of the new users still have problems to start since we have 8 wet benches. Not sure whether it will help if we start to require the annual refresh of the orientation. Looking forwards to the other responses. Thanks.

The overall process is fairly similar for internal/external users, but varies quite a bit depending on the specific project, admin circumstances etc. *Initial project and processing discussion* This can vary a lot depending on whether this is a brand new project, or a continuation of an existing project. A few hours of technical user support staff time is typical. *Admin set up* All users have to complete a form with all key information/fields/approvals (paper or electronic, many groups now also use DocuSign for this) and we manually enter it in our lab management system, set up lab access devices etc. That's fairly straightforward and takes 30min-1h max per user overall. For external users, it can sometimes take a little bit more time depending on the external organization requirements (setting up UM as a vendor in their system, POs, other arrangements etc). Our financial manager now takes care of most of those cases, but I think it rarely takes more than 1h or so of work. *Onboarding* Safety training is done via online modules (some from the university, others LNF-specific) with online quizzes and we get most results automatically/via email. Technical user support staff hold virtual information sessions (1h30 weekly) via zoom. We are working on moving those to an asynchronous delivery. We use a google spreadsheet to monitor/track all prospective users and their progress with required steps. This is still a work in progress (I started this spreadsheet in 2011...) and we are still working on making that tracking process more automated. I would say 30min-1h per user on this. All users have to go through a 1-on-1 30 minute access interview, usually with me. Once they have lab access, users also attend a new user orientation inside the lab, led by members of the user committee (users, not staff), 1h30 weekly for up to 4-5 people. After then, the new user is ready to start equipment and process training with their mentor, who can be a staff member or another lab user depending on the circumstances. So, on average, about 4-5h of staff time per new user is a good ballpark. But again, it can vary *a lot* depending both on the project and the admin requirements. I hope that helps! Happy to chat more about any of these if you want.
