From ahryciw at ualberta.ca Fri May 1 19:12:16 2020 From: ahryciw at ualberta.ca (Aaron Hryciw) Date: Fri, 1 May 2020 17:12:16 -0600 Subject: [labnetwork] Sputtering GdFeCo Message-ID: Dear colleagues, We recently had a request to deposit GdFeCo in one of our shared-use sputtering systems. We have no experience with this material, and would appreciate any advice you could share. The issue I've come across is a discrepancy between different SDSs for commercial Gd24Fe68Co8 sputtering targets. One vendor's SDS indicated that the material was not classified as hazardous and had no special handling or storage considerations; another listed Category 1 respiratory and skin sensitisation, water reactivity, and storage under an inert atmosphere, presumably by combining the hazards listed for the individual elements. Can anyone comment on the hazard and storage requirements of this material, especially in the context of an open-access facility ? For our shared-used systems, targets are swapped weekly, and there is currently no provision at our facility to store the target in an inert, moisture-free environment when it is not in the system. Is such inert storage necessary? Many thanks. Cheers, ?

I?m hesitant to comment on any hazards, as you will need to assess what is best for your facility. We treated it the same we would as other Co and Ni based alloys. I can tell you it is very sensitive to oxygen, so I do suggest storing it in an inert environment if possible. Because of its sensitivity, we also found that base pressure was extremely important. We could not achieve the necessary magnetic properties unless we deposited with a base pressure below 2e-7 Torr (at high 10e-8 scale, the properties were decent). We had the problem that our system was not load-locked, so we had to do long presputters as well. We also found it helped to do a little gettering prior to deposition by sputtering a lot of Ti or Ta in the chamber. Hope this helps. Best Regards, Matt -- Matthew T.

We took special measures to avoid contact between the suits in the dressing room. We have accommodated 50 users this week and 100 the next week. This is quite a dramatic restriction considering that under normal conditions we have counted no less than 500 active users each year. We plan to increase the number of users in the near future. We select the users mainly on the invoicing history of each lab during the last 6 months. Between 1 and 4 users per lab or per company are authorized depending of their past usage. Of course we also consider special cases carefully e.g. new professor recently arrived with no invoicing history. Access cards to enter the cleanroom are activated only for selected users. Only selected users are authorized to reserve tool (we control this point regularly).

Our lab and University is still closed but hopefully we can start to open up some of our research labs soon. I would be interested in hearing about any established practices for handling of cleanroom suits. In our case we have limited lab users so each will have the own gowning set (hood, suit, boots). We were planning to use plastic bins for storage of suits between shifts. But given that the virus can potentially survive on clothing for many hours (especially sealed up in an airtight box not able to dry), the question has came up whether we should be sending suits for laundry after every shift or possibly handing them with separation and trying to decontaminate garments with either steam or electrostatic spray systems.

As it looks more and more likely our fall semester is going to be online or a hybrid and therefore how I teach my lab based microfabrication course is going to have to change. I ended up recording videos on my processing for the last 3 weeks of the spring semester and will likely do that for the rest of the process (first 11 weeks) once I can get into the facility again. However, ZOOM, vidoes, powerpoints, animations are not going to get students the full hands-on feel for doing processing in a cleanroom and nothing really does. I did find a virtual fab created by KAUST - https://fablab.kaust.edu.sa - and they do have some tools that are the same as in my fab (EVG mask aligner). This allows the students to interact with the system - they use it for training from what I have seen. Does anyone else know if other facilities have produced a similar virtual experience? I am also looking for a processing software that allows a user to see a 2D/3D section of a wafer and do oxidation/etching/deposition on the wafer and see the cross section change after each process step. I was looking at the https://www.synopsys.com/silicon.html, but without a copy I have not been able to see if it does what I want. Not sure if anyone has had experience with this software? about to go check out Youtube.

I use it in my greenhouse and my plant tissue culture operations. It is composed of 20% quaternary ammonium salts, the specific "quats" and their ratio being identical to the ingredients in Chlorox Disinfecting Wipes but at higher concentration. In addition, Chlorox wipes a small amount of Ethylene glycol monohexyl ether. The Ethylene glycol monohexyl ether presumably acts as a solvent to dissolve oils which might mask surfaces from an aqueous solution. The combined concentration of quats in Chlorox Wipes is 0.368% versus 20% in Pi Quat 20. Attached are SDS .pdf's and appended are photos of Chlorox Wipes.

That being said, I think it can be a bit confusing to get started with. Silvaco Athena is another TCAD application I have used in past coursework at Rochester Institute of Technology that is more user friendly and I believe has cheaper licensing. It maintains the capability to do physics-based simulations of oxidation, diffusion, etc and the final 2D device geometry can be exported into their Atlas simulator to do electrical simulations. One of the professors in Microelectronic Engineering there might be a good reference on using it in coursework. If you are merely looking for a tool to visualize 2D cross-sections for an example process, you could look at the XSection add-on for Klayout, which would be a completely free option.This tool allows you to take a GDS, assign materials/processing to each mask layer, and then drag a 2D cutline across the top view of your mask at various points but is visual only and does not have physics simulation.

Message-ID: Dear colleagues, One of the users in our open-access facility recently expressed concern about x-ray production in electron-beam evaporation systems. Since the typical acceleration voltage in our e-beam systems is 7?10 kV, he was concerned that bremsstrahlung and characteristic x-rays would be generated during deposition, with a maximum energy of 7?10 keV (soft to hard x-rays), and that these x-rays would pose a health and safety hazard to an operator standing next to the viewport for ~30 minutes. A literature search yielded a few reports describing radiation damage to sensitive devices from x-rays produced during an e-beam metallization step, but I did not find any mention of related health and safety considerations. While some x-rays are undoubtedly produced, presumably there are reasons why they are not hazardous to an operator (e.g., perhaps total x-ray output is very small, majority of x-ray spectrum is low energy, x-rays do not penetrate stainless steel chamber walls or viewport windows, etc.). I would like to answer this user with specific physical arguments as to why the hazard is insignificant, however, so any advice you could offer to this end would be greatly appreciated. Many thanks.

In Denmark we had a complete shutdown of the public sector and thus the University and the cleanroom were shut down the 13th of March. We have device production in our cleanroom, there are about 5 companies that use our cleanroom for continuous device production. In order to protect these companies from possible bankruptcy we asked for special permission to reopen for commercial production only, already from the 20th of March. We proposed two people in the cleanroom at the same time, one at a time in the gowning area and scheduled time blocks for each company (initially one company at a time). This permission was granted and a few days later we had put measures and rules in place that allowed for this mode of operation. More companies were asking permission to fabricate components and soon (mid april) the scheduling became more and more complex, including nights and weekends to accommodate the demand for cleanroom time. It became clear that we had to find back to a more ?self regulated? scheme where people could book equipment on a first come first serve basis (as before COVID-19) while we could maintain the restriction of a maximum number of persons in the cleanroom. Literature and discussion with other cleanrooms convinced us that HEPA filters and the high laminar air flow in the cleanroom are an excellent protection against airborne virus infection especially in combination with face masks, so the main physical bottleneck was the gowning area. Fortunately we could (within a few weeks) establish a second gowning area to ease the load on the main ggowning. A very crude, home made and cheap solution involving stripes and tube isolation (see attached picture taken in ?the new, makeshift" gowning) allowed us to ensure distance between the (personal) cleanroom suits. During the shutdown we blocked all users from the booking system and access to the cleanroom. Regarding the restriction on number of persons in the cleanroom we introduced a new ?tool? in our booking system LabManager (it is a homebuilt ? over the last 20 years- booking, billing system including web shop) called "cleanroom presence?. Users are required to book "cleanroom presence" if they want to enter the cleanroom. If they book any standard bookable equipment they book automatically ?cleanroom presence? which is extending 15min before and after their tool booking. If the total max. number of persons at the ?cleanroom presence tool? in the booking system is exceeded, a warning is issued and booking of tools is not allowed. We can set the max. occupancy number of persons in the software, and the actual and maximum number is shown at the gowning areas so people area aware of the occupation status. We increased the max. occupation number gradually from 10 to 20 and are now at 30 people at the same time inside our 1300m2 cleanroom observing bottlenecks and behaviour. Our opening hours are currently restricted to weekdays from 7:00 to 19:00 with a staff member always present in the cleanroom. This is in order to observe if users gather some places (gowning, special tools) and if all COVID-19 special rules are obeyed. For commercial production we issue special permissions for companies to come in nights and week-ends. We hope to be able to open again for 24/7 in a few weeks. In order to ensure that users have read and understood the new rules and regulations they must register again to get access to the cleanroom (this also serves as a urgently need cleanup of our users list) and we require a (virtual) handshake, where they state that they have read and understood the new rules, and watched the videos on how to enter the cleanroom and the screencast concerning booking ?presence?in the cleanroom. Both can be found at our homepage: www.nanolab.dtu.dk. Here you can also find material concerning our COVID ?19 rules and measures if you are interested. At this time, May 28th, we have around 150 users that have registered again and as we speak we did not experience large queues or clogging. However we expect a bigger wave of user that want to register again following the ful reopening of the experimental research at the university during the coming days. So far our experiences are good, users generally obey the rules and are happy to be back in the cleanroom.

In-Reply-To: References: Message-ID: Hi Aaron. Back in 2015 we had similar concerns with our Balzers BA 510 thermal/ebeam evaporator. We had reintroduced thermal capability to our system and had modified our internal SS shielding to allow us to have a direct line of sight to the thermal melt through a glass slide mounted on the shield and through one of the window viewports. Prior to this we only used ebeam evaporation and the shielding blocked the viewport. As you have found, I was unable to find any literature on x-ray exposure concerns outside the chamber area. I contacted our Health and Safety department who helped conduct x-ray testing during ebeam evaporations of a few different materials. They found no measurable x-rays coming through the viewport or elsewhere on the chamber. This satisfied our safety concerns. However since the system was now identified as an potential x-ray producing source we had to get an Ontario ministry of labor x-ray permit and post it at the room doors and on the system. It basically requires us to get a new assessment if we make any changes or modifications to the system that could result in increased exposure. So we have piece of mind, but now a lot more questions when users see the x-ray signage. Hope this helps.

[External Email] Dear colleagues, One of the users in our open-access facility recently expressed concern about x-ray production in electron-beam evaporation systems. Since the typical acceleration voltage in our e-beam systems is 7?10 kV, he was concerned that bremsstrahlung and characteristic x-rays would be generated during deposition, with a maximum energy of 7?10 keV (soft to hard x-rays), and that these x-rays would pose a health and safety hazard to an operator standing next to the viewport for ~30 minutes. A literature search yielded a few reports describing radiation damage to sensitive devices from x-rays produced during an e-beam metallization step, but I did not find any mention of related health and safety considerations. While some x-rays are undoubtedly produced, presumably there are reasons why they are not hazardous to an operator (e.g., perhaps total x-ray output is very small, majority of x-ray spectrum is low energy, x-rays do not penetrate stainless steel chamber walls or viewport windows, etc.). I would like to answer this user with specific physical arguments as to why the hazard is insignificant, however, so any advice you could offer to this end would be greatly appreciated. Many thanks.

In-Reply-To: References: Message-ID: Aaron, I have asked your question to one of Harvard?s EHS health physicist?s and she gave the following answer: That's a good question and I'm glad people are thinking about this. So the general answer to this safety concern is that we can tell the dose rate outside an electron beam device is low and at a safe level because we measure it. You can take a look at the answer given by the Health Physics Society: https://hps.org/publicinformation/ate/q12299.html. Basically calculating the dose rate from an electron beam is very difficult because of differences in geometry, scatter, filtration, distance, interaction probabilities, etc, so the dose rate is almost always measured empirically. Also very little empirical data on x-ray dose below 50kV exists because it is too low for traditional x-ray applications (medical x-rays and other imaging) plus it's so low that detector efficiency drops. I survey electron microscopes every two years to check for leaks; so far I've never had a measurement above background although ~15 years ago there was one leak detected from a faulty gamma camera. What we can do is look up the mass attenuation coefficients from the NIST website (https://www.nist.gov/pml/x-ray-mass-attenuation-coefficients) to get an idea of the x-ray attenuation through a glass viewport. Let's assume the max 10kV electron beam translates into a 10kVp x-ray source (untrue, but it's the most conservative estimate). The average energy of a typical x-ray source is 1/3 of the peak voltage, or 3.3kV. The mass attenuation coefficient for 3.3 kV x-rays for borosilicate glass is roughly 400. If the glass is 0.25cm thick and its density is 2.23 g/cm^3 (given in NIST table 2), then the intensity drop from this shielding is given by: I/Io = e^(-u/p*p*x) = 1.4*10^-97 So the penetration of 3.3kV x-rays through .25cm glass is already really small, and that's assuming it's an x-ray beam pointed directly at glass with no other obstructions. Even if the x-ray dose rate reaches what we know of for x-ray fluorescence devices that can reach >3000 rem/hour on skin contact, this becomes negligible through the glass shielding. This doesn't say anything about leakage however. That's why we measure. From: labnetwork-bounces at mtl.mit.edu On Behalf Of Joseph E.

In-Reply-To: References: <3ca1baede00d2fe5a39a2efd85b00c77ed101bb3.camel@fabsurplus.com> Message-ID: Hi Aaron, The State of Ohio has a schedule for testing/measuring/auditing all x-ray producing devices (dentistry x-rays, XRDs, electron microscopes, etc.). The electron microscopes are a category in themselves and they eventually considered our ebeam evaporators in the same category (along with my 100kV electron beam lithography tool). Even though they knew that the voltage on the evaporators was much lower than the SEMs/EBL, they maintained them in that category. For many years our University EHS radiation safety officer would measure/audit these equipment yearly, the State every 3 years. Never once were any of the measurements above background. Eventually, they no longer required them to be measured/audited. New instruments and any significant modifications to existing instruments, likely still require an initial measurement by our safety officer. Typically, the instrument vendors require this as well as part of the tool qualification (although maybe not for ebeam evaporators). We were required to train our users on the hazards of x-ray, the signs/symptoms of exposure, and give notice of which tools generate them. I wrote a spec/document from which we trained and can share it with you off-line if you?d like. It does have a lot of specifics to the State of Ohio, but it?ll give you an idea. We required that users be ?certified? in both the x-ray safety document as well as the specific tool before they could use any system that generated x-rays. My feeling was that it is good for users to be aware of this for their education, even knowing that the risk was low. Many of them will be tool owners themselves at some point and it is good to consider, the ?you don?t know what you don?t know? mentality. Long story short, if you have any questions your equipment vendor should have answers on this topic. What shielding or safety measures, if any, they use and how they were determined would give most users a good understanding and comfort in their safety.

Dear colleagues, Thank-you all for the excellent discussion and suggestions?this has been incredibly helpful. Beyond allaying the fears of the user who raised the concern, going forward, we will be sure to incorporate an explanation of these considerations when training users on our evaporators. Stay safe and healthy. Cheers, ?

They had a low accelerating voltage of 8KV, but we had some tools with a FIB option installed (Fast Ion Bombardment), and that operated at up to 16 KV. We had a viewport above the source area, so as to have a reality check on what was really going as one poked around inside the vacuum chamber. The viewport had leaded glass. This might be erring on the side of excessive caution, but such view port glasses are readily available for purchase in the market place, so that's what I'd suggest. -- [SDI Fabsurplus 20 years] SDI Fabsurplus LLC Stephen Howe Company Owner email: info at fabsurplus.com Mobile: +1 830-388-1071 Skype: stephencshowe WWW.FABSURPLUS.COM Linkedin: https://www.linkedin.com/company/sdi-fabsurplus Twitter: https://twitter.com/fabsurplus Instagram: www.instagram.com/fabsurplus Facebook: www.facebook.com/fabsurplus Featured Sales Items:- Fabsurplus.com Closed-Bid Warehouse Clearance Sale May 2020 Applied Materials Centura 5200 EPI HTF-EPI Deposition, 3 CH ATM 200 mm Axcelis NV-GSD-200E2 Medium Current Ion Implanter, 180kV, 150 mm Important Notice The information contained in this email is confidential.

We had reintroduced thermal capability to our system and had modified our internal SS shielding to allow us to have a direct line of sight to the thermal melt through a glass slide mounted on the shield and through one of the window viewports. Prior to this we only used ebeam evaporation and the shielding blocked the viewport. As you have found, I was unable to find any literature on x-ray exposure concerns outside the chamber area. I contacted our Health and Safety department who helped conduct x-ray testing during ebeam evaporations of a few different materials. They found no measurable x-rays coming through the viewport or elsewhere on the chamber. This satisfied our safety concerns. However since the system was now identified as an potential x-ray producing source we had to get an Ontario ministry of labor x-ray permit and post it at the room doors and on the system. It basically requires us to get a new assessment if we make any changes or modifications to the system that could result in increased exposure. So we have piece of mind, but now a lot more questions when users see the x-ray signage. Hope this helps.

[External Email] Dear colleagues, One of the users in our open-access facility recently expressed concern about x-ray production in electron-beam evaporation systems. Since the typical acceleration voltage in our e-beam systems is 7?10 kV, he was concerned that bremsstrahlung and characteristic x-rays would be generated during deposition, with a maximum energy of 7?10 keV (soft to hard x-rays), and that these x-rays would pose a health and safety hazard to an operator standing next to the viewport for ~30 minutes. A literature search yielded a few reports describing radiation damage to sensitive devices from x-rays produced during an e-beam metallization step, but I did not find any mention of related health and safety considerations. While some x-rays are undoubtedly produced, presumably there are reasons why they are not hazardous to an operator (e.g., perhaps total x-ray output is very small, majority of x-ray spectrum is low energy, x-rays do not penetrate stainless steel chamber walls or viewport windows, etc.). I would like to answer this user with specific physical arguments as to why the hazard is insignificant, however, so any advice you could offer to this end would be greatly appreciated. Many thanks.
