Prior to last week the tube was more on the black-ish color side and it "suddenly" turned red, flaking over the wafers. Our tube seems to be due for a swap but still, anyone has encountered this kind of deposit ? We run regular Bosch processes as well as glass and fused silica etch using a little bit of methane. We suspect methane because the red color is can be seen in the methane gas port (left side hole) whereas the gas port for all other gases is clean. However that could a coincidence, we don't know ! Attached is a picture of the tube.

Message-ID: <529D0049.9040206@stanford.edu> Labnetwork community: Our faculty advisory board has asked us (the Stanford Nanofabrication Facility) to plan for the installation of a carbon nanotube (CNT) furnace and a graphene reactor in our clean room. Specifically, they are looking at the FirstNano EasyTube 3000 and the Aixtron Black Magic 4" Pro, respectively. I'm interested if anyone has experiences to share with equipment of this type in a shared clean room environment. Specifically, is there anything special that you do to protect the person loading/unloading samples ... and other nearby folks ... from possible particle exposure during normal operations of these tools? Also, are there any special precautions that you take for the staff members working on either the reaction chamber, the vacuum system, or downstream abatement systems? Finally, are there anything that you do specially to protect the outside environment from possible particle generation? Note: our EasyTube 3000 should be outfitted with the FirstNano EasyExhaust Burn Box. It is not obvious that the Aixtron Black Magic in the graphene reactor has any sort of included burn box ... although, by default, if we did nothing else, the pump exhaust would still be routed to our laboratory-wide water scrubber.

They are even marketed for cleanrooms. I haven't used either of these two units, but I have used their PTU300, which also logs barometric pressure. At a previous semiconductor facility, our wet oxidation process control went berserk every time a storm came through. I installed one of the PTU300 units and dynamically adjusted oxidation times to compensate for barometric pressure. It was quite helpful. I've been gone from that site for several years now and they still use it. tonyO Tony Olsen Nanofab Cleanroom Supervisor/Process Engineer University of Utah 36 S Wasatch Dr, Suite 2500 SMBB Salt Lake City, UT 84112 801-587-0651 office 801-587-3077 fax www.nanofab.utah.edu From: Mark Heiden [mailto:mheiden at engr.ucr.edu] Sent: Monday, December 02, 2013 12:47 PM To: labnetwork at mtl.mit.edu Subject: [labnetwork] Lab Monitoring Solutions Dear Colleagues, We are closing in on starting up a new class 1,000/100 facility here at UCR and I am looking for a low cost solution for remote monitoring of room conditions for the 2 new clean bays.

We have already chosen a method that should suit our needs just fine. The Omega iTXH-D3 Virtual Chart Recorder is the solution we will try. http://www.omega.com/pptst/ITHX-D3.html This unit sends data over Ethernet with embedded software that looks easy enough to use. We can mount it in the chase, plug in a power supply and Ethernet cable with only the probe running into the room. Omega also offers a unit with local display for a little more cost but we decided that it may just cause unnecessary hand wringing by users if the room conditions move around even within spec. Again, the labnetwork has proven a very useful tool!

The facility will have more than 8,000 square feet of class 100 and class 1000 space and will be outfitted with a complete suite of new equipment. The nanofabrication facility is located within the new Interdisciplinary Science and Engineering Laboratory, which also houses state-of-the art microscopy and materials characterization facilities. We have several faculty searches this year that may be of interest to candidates wishing to take advantage of our new nanofabrication facility and capabilities. I would be grateful if you could circulate this announcement and the attached advertisements to the users of your nanofabrication facilities and any other potential faculty candidates. Personal recommendations of candidates would also be very much appreciated. One position is in the area of nanoscale engineering. This a college-wide search for a candidate working in the areas of nanoscale materials, devices, and fabrication. Areas of research interest include, but are not limited to, photonic devices, light sources, sensors, detectors or actuators. Candidates conducting research that complements existing strengths in biomaterials, optoelectronics, photonics, renewable energy or magnetics are especially encouraged to apply, but the search is quite broad and I strongly encourage candidates to apply even if they do not overlap with these areas. The home department for this faculty member will be determined by the best overlap with their area of research and teaching expertise. The second search is for a Clare Booth Luce Assistant Professor in Hard Materials. This position, established with support from the Henry Luce Foundation, is for an outstanding woman doing research in the area of hard materials and provides significant discretionary funds for career development. Specific areas of research interest include, but are not limited to, electronic and optoelectronic materials, materials for energy conversion/storage, nanomaterials, and composite materials. Again, the search is broad and we strongly encourage candidates to apply even if they do not overlap with these topical areas. The primary appointment will be in Mechanical Engineering or Materials Science and Engineering with additional appointments in other departments as appropriate. The third search is for a senior faculty member in our new Biomedical Engineering program. Many areas of biomedical engineering are of interest, including the development of nanofabricated biomedical instrumentation, devices and sensors. Links to descriptions of these positions can be found at http://www.udel.edu/udjobs/. The attached pdf ads describe the three positions in more detail and provide contact information for each job.

However, we do have a reflux condenser that allows clients to set up their own concentrations if they desire. I do not prefer this practice due to expense, especially with TMAH at $650 per case.

If unused it is at room temperature and heating to 70-80C is quite fast for usage. We believe it is safer this way as users do not need to make the KOH mixtures which include some hazards. We also monitor regularly the pH of the solution and top up KOH whenever required.

A general tendency is to think that OPEX will start low in first year and go up as usage would ramp up. Though this is an acceptable way of thinking you need to keep in mind that at the start you need for instance to buy all gas cylinders which again depending on the facility might be a non-negligible amount. This also stands for metals/materials for e-beam evaporation and/or targets and that can be very high if precious metals are included. At ACT Node our typical consumable budget excluding maintenance contracts is about Au$ 350k per year ex staff salaries.

As you know, sometimes these etches can take a long time so it ties up valuable bench space. Having done much KOH etching myself, I empathize. I hope to change strategies as soon as the opportunity and funding permits. It will be a hybrid of the two approaches. I hope to have a custom bench built to hold 2 -3 specially designed stations, each equipped with quartz beakers (various beaker sizes variable) on a stirring hotplate with a nicely sealed water cooled reflux lid with a thermometer (or TC) well, excellent lighting and good visibility of the sample during the etch, maybe even a camera. Most frequent complaints with our current bench are: Not enough user capacity so need more than one. Variability in water content despite the refux coils. Uncertainty over what the previous user may have done to the bath. Can't use it for custom mixtures. It takes too long a needs to be cooled, drained, remixed for the next user. Vince Vincent K.

If unused it is at room temperature and heating to 70-80C is quite fast for usage. We believe it is safer this way as users do not need to make the KOH mixtures which include some hazards. We also monitor regularly the pH of the solution and top up KOH whenever required.

We used epoxy coated spiral duct for all the corrosive exhaust as a cheap alternative to large bore PVC ducting. That was back in 2000 and the ductwork is still in use today. We installed wet benches that incorporated the proper exhaust condenser equipment to catch the majority of acid/base fumes before going out to the exhaust system. I will caution you that if the corrosive media you will be using is going to be in an aerosol form or used at high temperatures where there is significant out gassing, you should look at ductwork made from PVC or other suitable plastics. If you are using wet benches that have the proper exhaust systems built in, i.e. condenser coils for hot acids or bases to be condensed and caught in the wet bench itself, then you will probably be ok with the epoxy coated ductwork, if of course you have quantified the total effluent in the exhaust stream first!

There are numerous things that could cause your issue you should inspect the arrays in the pump and numerous other things but the easiest check that you can do to start is to take a look at your helium pressure, you should have a send and return gauge on your compressor and they should be operating within limits that are required by the manufacturer. Check those gauges first and see if they are within the specified tolerance, you may be either low on helium or of the Delta P is to great you may have a dirty adsorber. If your helium pressure has dropped below what the manufacturer recommends you can simply recharge it and perform a regeneration and you should be fine (given you don't have a helium leak somewhere), make sure to use 6.0 grade helium and the proper helium gas filling manifold and recharging procedure. I have pasted a troubleshooting guide for you from a CTI system but a lot of the principles will apply to your pump. If you still have problems feel free to give me a call at the numbers below. Table 4-1: Troubleshooting Procedures Problem Possible Cause Corrective Action High base pressure of vacuum system, and a cryopump tem- perature below 20K. High base pressure of vacuum system, and a cryopump tem- perature above 20K. Air-to-vacuum leak in vac- uum system or in cryopump. Check cryopump relief valve for proper seating. Check cryopump for leaks. Check vacuum chamber and Hi-Vac valve for leaks. High partial pressure of non- condensables (helium, hydrogen, or neon) within the cryopump because the 15K array has reached full capacity. Regenerate the cryopump as described in Section 3 - Regeneration. One of the arrays is loose, which is preventing good thermal contact with the cold station. Warm the cryopump to ambi- ent temperature and retighten the array mounting screws to 15 - 20 in. lbs. Decrease in cryopump cold head performance. If the helium return pressure gauge reads below the nor- mal-operating return pres- sure 60-85 psig (415-590 kPa), add gas as described in the appropriate Compressor manual. High partial pressure of non- condensables (helium, hydrogen, or neon) within the cryopump because the 15K array has reached full capacity. Regenerate the cryopump as described in Section 3 - Regeneration. Excessive thermal load on frontal array. Reduce the thermal radiation load by 1) shielding the cry- opump or 2) lowering the temperature of the radiating surface. Table 4-1: Troubleshooting Procedures (Continued) Problem Possible Cause Corrective Action Cryopump fails to cool down to the required operating tem- perature or takes too long to reach that temperature (20K). Low helium supply pressure. Add gas as described in the appropriate Compressor manual. Compressor problems. Refer to Troubleshooting sec- tion of the appropriate Com- pressor manual. Vacuum leak in vacuum sys- tem or cryopump. Check the cryopump relief valve for proper seating. Check cryopump for leaks. Check vacuum system for leaks. Incomplete regeneration may not have fully cleaned the adsorbing array. Partial pres- sures of non-condensables (hydrogen, neon or helium) may remain. Regenerate the cryopump as described in Section 3 - Regeneration.

This material has superior corrosion resistance while maintaining its structural integrity in the unfortunate event of a duct fire. The drawbacks are the price and the fact that it cannot be modified in the field. Some plastic (CPVC) can be used for final transitions but it must be approved by your insurer. Our system has been in use for 6 years and has no signs of breach or corrosion even when we remove a fitting for modifications. In the last industrial semi-manufacturer that I worked at, it had been in use for over 15 years and it was still in perfect condition. I have become aware of other newer materials that might be less expensive than PSP but I have no experience with them. Insurance companies tend to dictate these choices and it might be a good idea to consult with them since they base their recommendations (requirements) on laboratory failure analysis. I hope you have a good budget for this!

Here at the Lurie Nanofab we're using fiberglass material in the original fab areas (vintage 1986), and teflon coated stainless steel in all of the renovated, and new construction, areas (vintage 2006-2008). When we looked at the various materials for our new facility, the teflon coated material was a HUGE cost savings on our project, a savings somewhere north of $160K between the two projects. The big advantages were ease of installation (reducing the labor costs), and the fact that the ductwork no longer required fire suppression. Even though fiberglass is fire resistant, it'll still burn/melt/vaporize (I can tell you a story about a local fab that had that happen). We're so pleased with the teflon coated stainless material, that even in the original fab locations where we're reworking the exhaust connections at benches and tools, we're installing the teflon coated stainless material. By the way, we're using the PSP material from Fab-Tech. If you have any additional questions, just give me a call, I'd be happy to share our experiences in working with the material.

The material meets the FM Global 4922 standard for cleanroom use. The main advantage to using FRP is that duct detectors and the associated monitoring system are not required due to the material's flame propagation characteristics. The main drawback to FRP is its cost. The duct and fittings are quite expensive, although that cost is somewhat mitigated by not needing a duct detection system. Our FRP ducting has been in service since October 2005 and has been essentially trouble free. It comprises our entire corrosive exhaust system. FRP is also used outdoors for the ducts leading to and from our exhaust scrubber and has weathered the extremes of Indiana weather pretty well.

Some people have had bad coatings and hence bad experience. I had triple coat and wet sponge low voltage (Holiday detector) test verification of each piece. The previous Berkeley Microlab also used epoxy coated galvanized and had 28 corrosion free years.

The Teflon lined stainless steel which is flanged/gasketed/bolted or welded is especially important if you are combining potential effluents containing pyrophorics or hydrogen (eg CVD or LPCVD exhaust/purge) in the same duct as the wet hood (acid or base) effluent, because you have the risk of explosion, fire and corrosion in the same exhaust stream. Also we have been able to modify the Teflon lined stainless in the field at many jobs, it just takes special skills and a kit from PSP to do a tap in the field for modifications. This material is a long lead item and also quite expensive, but it has been much safer than any other material. FM prefers it because it is "factory made" rather than wrapped or coated in the field. We did use Plasite coated heavy gauge galvanized ductwork in the same application at a couple of Northern CA projects but this was not preferred because the plasite is coated at the fabrication shop and there can be voids, think areas or other quality control problems that are hard to find. It is also heavier. If there is no risk of overheating, fire, or explosion and only corrosion resistance needed, the Fiberglass reinforced plastic "field fabricated" duct is good if made by talented fabricators, although any Fire in the facility will also destroy it, and it makes really awful destructive and corrosive smoke when it burns. PVC has similar characteristics, and neither of these materials meet the 25/50 flame and smoke spread requirements of some H-5 codes. (depending on IBC year, I believe).

We used Plasite coated galvanized duct. Around 2000 we had a duct fire over our LPCVD furnaces, gallons of accumulated pump oil in a lateral. Following the duct fire the duct was inspected by a third party for integrity, found mostly in excellent shape and put back into service. About 10 feet of the lateral was replaced because it was damaged and actually glowing red during the burn-off of that oil (rather impressive when your holding the fire extinguisher). In 2011, when we moved to our new lab, those same ducts were inspected by a third party for integrity to see if they could be re-purposed. Note that both laterals and risers of this same ducting serviced our acid and etch wet process station. The main riser saw all of the accumulated exhaust. After 26 years of harsh service these ducts were deemed in excellent condition with more service life. To be fair there were some areas that needed repair. The uncoated dampers where the flexible PVC tubing from the wet process stations transitioned to the duct were corroded. These dampers were dynamic and areas of them weren't coated. An added benefit to Plasite was when we needed to modify the ducting our HVAC contractors and our machine shop could fabricate new sheet metal and coat the modified pieces plus, in site coat the modified with Plasite. I cannot give you a cost/benefit for other ducting. If anyone asks me for my recommendation I will, without hesitation recommend Plasite coated ducts for both their chemical resistance and for their fire-ratings as well as the added benefit of being reconfigurable at modest cost.
