Birck operations during critical research support
by Shakouri, Ali 25 Mar '20

25 Mar '20

Dear All, Governor’s announcement and EVPRP’s follow up email on Monday highlighted that only critical research should continue starting from Wednesday 3/25 until the governor’s order is rescinded, currently scheduled for April 7. The message below from EVPRP gives the definition of critical research and explains ramp-down procedures. Here are some additional details about Birck related issues: * Starting from later this morning (Wednesday), we will shut down all toxic, flammable, and hazardous gases. This is similar to our operation during the winter break with the exception that we can only support critical research activities approved by EVPRP. * If anybody is planning to do critical research, you need to fill up the appropriate form<https://www.purdue.edu/research/covid-19/critical-research.php> on EVPRP website AND email Birck leadership so that we can evaluate facility and staff needs. So far I have received request from one group for COVID-19 sensor work. * In your email to Birck, please identify everything needed: access to specific labs, name and email of researchers who need access, necessary consumable and chemicals and how often, shipping/receiving needs, hazardous waste disposal, etc. * User who need to access the facility for critical research should follow strict guidelines for physical distancing and safety and hygiene practices. * We ask that non-critical research is ramped down at the latest by Thursday 3/26 at 12 midnight. Please go over the Research Laboratory Ramp-Down Check List<https://www.purdue.edu/research/covid-19/critical-research.php> on EVPRP site (see the forms on the right hand side). This will allow our support staff to do walk throughs and inspect the facility on Friday. * No consumables, supplies or equipment will be ordered for non-critical research activities * After Friday, there will be no receiving of packages at Birck. If you are expecting a package that may arrive after Friday, you need to contact the supplier to delay or cancel shipment. Packages in transient will be held at Purdue’s Materials Management Distribution Center https://www.purdue.edu/materials/. Other packages send by express carriers e.g. Fed Ex & DHL may be held at their local depot. Please check into package pickup requirements at each of the shipping locations on ID requirements for package pickup. * For more information (including shipment and receiving of materials for critical research), please contact Mary Jo Totten (tottenm(a)purdue.edu<mailto:tottenm@purdue.edu>) and Mark Voorhis (mvoorhis(a)purdue.edu<mailto:mvoorhis@purdue.edu>). * Liquid nitrogen deliveries to our bulk tank will continue, and specific staff members will periodically fill dewars for small uses. * Staff members will periodically walk through the building to check on critical equipment and facilities. Staff will be working from home as much as possible as we would like to minimize their exposure. * After the ramp-down of non critical research on Thursday, access to Birck will be limited to ONLY essential personnel, those with approved critical research or critical machines that require regular check-in during stand by (e.g. MBEs). The restricted access will be through the north east (main) entrance to the building. Please do not open exterior doors to allow unauthorized personnel into the center. Zhihong, Sunil and I are indebted to Mark, Ron, Steve and our dedicated building and engineering staff who are making sure that our critical infrastructure is well maintained and users for critical projects can work in a safe environment. Thanks also to Sam Peana and NSAC who have great initiatives (e.g. virtual activities for students) which is so important in these unprecedented times. COVID 19 situation is evolving very quickly. We will be in touch if there are any changes and before April 7 to give an update about our operation. I hope everybody is staying healthy and safe. Please let Zhihong, Sunil and I know if you have any suggestions or comments. Best regards, Ali Ali Shakouri Mary Jo and Robert L.

Thank you for your efforts! Yesterday, Governor Holcomb’s office released an executive order for Hoosiers to remain in their homes except when they are at work or for permitted activities, such as taking care of others, obtaining necessary supplies, and for health and safety. The order provides an exception for “[e]ducational institutions . . . for purposes of . . . performing critical research or performing essential functions,” provided that social distancing practices continue to be followed. The order is in effect from March 25 until April 7. Research performed on the Purdue campus and at our locations across the state must comply with the Governor’s order. This means that laboratories should safely and responsibly ramp-down noncritical research in a manner that allows for all of our research activities to quickly ramp back up when restrictions are lifted. When current social distancing (6 ft) and density (1 person per 120 sq. ft.) can be maintained, critical research and support functions in campus laboratories, agriculture centers, and field sites are defined as follows: Critical Research * Work that is directly related to preventing, containing, or treating COVID-19. * Work that is directly related to national security. * Work that if discontinued would pose a safety hazard. * Laboratory or field work that if discontinued would result in significant data or sample loss. * Longitudinal or seasonal work that if discontinued would result in significant data or sample loss. * Clinical trials or human subject research that if discontinued would result in significant negative impact on patient care or human health. * Seasonally dependent agricultural research that would have critical implications for human and animal health as well as food security. Support Functions * Research administration, regulatory, and support functions that are required by law. * Work that maintains critical animal populations. * Work that maintains critical plant populations, cell lines, and other living organisms. * Work that maintains critical samples, materials, and reagents. * Work that maintains critical equipment in facilities and labs, whether operational or in stand-by mode. * Work necessary to ramp-down noncritical research after March 25. To continue these critical research activities in Purdue campus laboratories, agriculture centers, or field sites after March 25, principal investigators or facility/site directors should complete a brief online Critical On-Campus Research Continuity Information Form available on the Purdue COVID-19 Research website<https://maillinks.purdue.edu/t/39311964/1558914122/83579050/0/124711/?x=079…>. All personnel should follow previously announced guidance on social distancing/safety hygiene practices, human subjects and animal research, use of proper lab and safety equipment, and use of buddy system in labs with hazardous materials. Additionally, researchers and staff who are sick, have returned from travel outside of the state, or have concerns over their personal health and safety should not come to campus. Research and support functions that fall outside of this definition should be safely and responsibly ramped-down using the Research Laboratory Ramp-Down Checklist by March 27. Removing university chemicals, materials, equipment, or animals to recreate experimental laboratories at off-site locations is not permitted. Sign templates that should be completed and posted on all laboratory doors are also available on the website. During this time, we strongly encourage you to continue all possible research and scholarly activities remotely. This includes work such as data analysis, writing projects, literature reviews, or online learning (coding, statistics, etc.). Be sure that group members are well equipped to work remotely (VPN, Duo, etc.), and that special accommodations and approvals are obtained for use of proprietary or protected data and computing resources. Purdue and Indiana University are issuing similar research guidance at this time. It is our hope that this consistency will help to support our researchers who are collaborating across our universities, including critical research that is addressing the COVID-19 crisis. Please know that we are here to support you. Our sponsored programs, regulatory affairs, program development, and many other teams have remote plans in place and remain operational. Feel free to contact us by e-mail with questions or concerns.

Birck Operation: COVID-19 Student Information
by Shakouri, Ali 22 Mar '20

22 Mar '20

To All Birck Students: Dear All, I understand that some students cannot work from home and need to use our labs and cleanroom for their research. Birck as a shared facility can function only when users obey strict sanitizing, hand washing and social distancing rules. Students should minimize the use of shared offices, kitchen and other public spaces especially if they can’t keep 6ft distance. Also plan so that you minimize time in the cleanroom or labs and visit the facility only once per day. Students who need to work close to each other, should coordinate their schedules to minimize overlap. I strongly encourage each faculty member to ask their students who have been traveling out of state to stay home for 14 days. There is a widespread shelter in place in several states and since there are no signs early on, it is important that we minimize the risks to other users. Please also review Sam’s email from yesterday. I appreciate very much NSAC’s great initiatives in these critical times. Please let me know if you have any suggestions or comments Best regards, Ali On Mar 20, 2020, at 3:37 PM, Turner, Jaime J <jjbiggs(a)purdue.edu<mailto:jjbiggs@purdue.edu>> wrote: On Fri, Mar 20, 2020 at 1:53 PM Samuel Peana <speana(a)purdue.edu<mailto:speana@purdue.edu>> wrote: Just a few notes on behalf of NSAC regarding the virus particularly how it affects Birck: 1. Please, please, please conserve the solvent gloves, the blue booties, and the bouffant caps. -The solvent gloves in particular are low and can be washed with IPA after use and reused! Please make every effort to conserve them as supplies in the coming months are uncertain! 2. Please wash your hands before entering any lab or the cleanroom! 2. If you do not need to work in a lab with equipment, you may work remotely. This reduces the chances that we will have a spread of this virus in the Birck community. -I am working with NSAC to release instructional videos tomorrow on how you can prepare your computer for remote workand how to use Purdue's online resources remotely. 3. I know many of us skip reading emails from admin but please make sure you are receiving emails from our director (shakouri(a)purdue.edu<mailto:shakouri@purdue.edu> ) through the BNCall list to get the latest news and guidelines regarding our building. Additionally, I have included our directors previous email as a post script to this email. 4. As per Theresa Mayer's email from Discovery Park yesterday (make sure you read those too!). Please do not start long experiments or fab runs since your work could be shutdown on relatively short notice. -I also advise that at the end of each day you "safe" your work. IE leave everything in a state that if the center does not open the next day you can return in a month or two without losing track of what you were doing or having samples ruined. 5. NSAC will be suspending all in person events till this thing is over. I am working with our social committee, sports committee, academic committee, and improvement committees to develop a strong online community for socializing, exercising, and also academic growth. -We are currently looking to put together a gaming community, online exercise groups, and also to transfer coffee hour online. (If you would like to present your research online please sign up here<https://docs.google.com/forms/d/e/1FAIpQLSdgDxNWFBnTcks57dNe08508zticCprPVb…>! ) 6. If you are worried you are sick with this virus or have questions regarding the response from the state of Indiana please consult this webpage: https://www.in.gov/coronavirus/ which has information on where to get tested, and treated. Additionally, there is information regarding Indiana policy such as restrictions and gathering guidelines. 7. As dark as everything looks right now, remember, Purdue has been around for 150 years and has thrived despite two World Wars, and a variety of pandemics and crises. This too will pass, and we will come out of this stronger and more focused than ever. I wish you all the best and don't hesitate to contact me if you have any questions or suggestions! Sincerely, -Sam Peana President of NSAC 2018-2020 Prof. Shakouri's email: Dear Birck Research Community, Purdue research operations are continuing per the EVPRP’s guidelines: https://www.purdue.edu/newsroom/releases/2020/Q1/need-to-know-info-about-co… (see sidebar, recent message from Theresa Mayer and Linda Mason) I would like to provide some additional information regarding our work here at Birck. Working from home: Purdue recommends working from home/ telecommuting wherever possible. I will meet shortly with engineering, building and admin staff managers to identify how we can implement this while maintaining our facility open. Reuse shoe covers, bouffant caps, and veils: Due to healthcare providers stockpiling these items we are asking users to reuse shoe covers, caps, and veils for longer periods than normal. This will allow our operations to continue and will support healthcare workers who are needing these items for their own protection. Wash hands prior to entering labs or cleanroom: We now require anyone entering a lab or the cleanroom to thoroughly wash their hands prior to entering. The CDC recommended procedure for hand washing should be strictly followed. Use hand sanitizer if available: We’re trying to keep sanitizer available but it is becoming in short supply. Please continue to use it if available. Custodians Support Activities: The Birck custodians are wiping door handles and other common surfaces with disinfectant on a more frequent basis. Shipping Receiving: Added steps and precautions are being taken by sanitizing the outside of all packages during the receiving process to protect our personnel and those receiving packages. This may cause a short delay with the receiving process. To help with limiting the number of packages being handled, we request to stop all personal deliveries to the centers loading dock. Bulk process gas supply: Through the Purdue purchasing organization we have been in contact with our bulk gas suppliers, Messer, Indiana Oxygen, and Praxair. All vendors do not anticipate any disruption in delivery of our bulk gases to the facility. Additionally our engineering staff has tied into the telemetry units and can now monitor the levels of all bulk gases except CO2. Traveling back to Birck: Currently CDC recommends self-quarantine for a period of 14 days after travel to high risk countries. With the quick spread of virus in many countries, including several states in US, and given that there could be no signs for up to two weeks, I recommend that we are extra cautious following the recommendations after any travels. By avoiding unnecessary face-to-face meetings, we can minimize unintended spread of the disease among colleagues. Of course, working remotely should be coordinated and approved by managers or faculty advisers. Additional pandemic contingency plans: We continue to develop additional contingency plans if EVPRP decides to limit or curtail research work. This planning includes alternating shifts and telework. At this time these are only plans that have no timeline for deploying. If you have sensitive tools that require careful shutdown or attention while idle, it will be good to include them in the plan. Please contact Ron Reger (rreger(a)purdue.edu<mailto:rreger@purdue.edu>) and Mark Voorhis (mvoorhis(a)purdue.edu<mailto:mvoorhis@purdue.edu>). These are unprecedented times and we’re working on a daily basis to keep our community safe while anticipating possible future scenarios. Please let me know if you have additional input, ideas, suggestions, or concerns. <image001.png>

Summary from BNC Faculty Meeting - March 10th
by Shakouri, Ali 12 Mar '20

12 Mar '20

Dear Colleagues, We had a packed agenda and good discussions at our Birck Faculty Meeting on Tuesday March 10th. Sunil described latest tools and their installation schedule. Thanks to Mark, Ron, Marcie and their staff, we will have some great new capabilities (cluster sputtering for magnetics, AJA superconducting deposition, ICP RIE, dispensing tools, HT-GPC, etc.). Sunil also highlighted the staff engineering excellence initiative (electronic logs, process quality monitoring, contamination control, and training wait time analysis). Summary of a lab accident and facility evacuations were also provided. Zhihong gave a detailed overview of Birck Annex planning based on the extensive input from our dedicated faculty and staff (see below additional details). She also gave updates about the electron microscopy and electrical characterization cores. We provided an overview of communication and outreach activities by Jaime, Neil and others (atrium displays, nanodays, sharktank storytelling competition and faculty seminars). On the financial side, we had a good increase in our overall income in FY20 and a strong grant support. I presented an overview of proposed new rates effective from July 1st. We will streamline lab access and recharge centers. Comparing to the last rate review (2013), we will have an increase of about 10% (approximately equal to the inflation during this period). A summary of Birck investment in new equipment since 2012 was provided. Our faculty have been very active, complementing our tool investment using general funds by 200%. We have been able to bring latest capabilities at a level of $2M/year in par with the best nanotechnology centers in US. As our facility ages, we need extra support for building maintenance and we have been in contact with EVPRP. We briefly discussed about the impact of COVID-19. We should receive some guidelines from EVPRP shortly. Currently, research operations continue but we need to plan for situations where we may be required to ramp down activities. Please let me know if there are essential labs/personnel or sensitive equipment for which we should plan. With travel restrictions and canceling of bigger events (>50 people), we should have more time to work in the lab and do research. It is a good time to do fabrications and characterizations, since data analysis is done more easily from home! Birck's core strength is that we are a shared resource for the whole university. Let me know if you have any suggestions or ideas to expand our impact on campus or to help bring new centers of excellence to Purdue. The link to meeting viewgraphs are provided below. Please don't hesitate to let Zhihong, Sunil or me know if you have any suggestions or comments. Best regards, Ali PS. Here is a link to our viewgraphs (please keep this information internal to Purdue): https://www.dropbox.com/s/qc529zx154y2a2t/BNC_Faculty%20March%202020print.p… PPS.

Reminder: BNC Faculty Seminar Series - Presenter: Dallas Morisette - TODAY, Thurs., 3/12 @ 12noon in BRK 2001
by Turner, Jaime J 12 Mar '20

12 Mar '20

Dear all, A gentle reminder, Dallas Morisette<https://engineering.purdue.edu/ECE/People/ptProfile?resource_id=77034&_ga=2…>, Research Assistant Professor of Electrical and Computer Engineering will present this week’s faculty seminar series today, Thursday, 3/12 @ 12pm (lunch provided) in BRK 2001. The first half will be an overview of research and the remainder will be open for questions and high-level discussion of collaboration opportunities that can lead to future center of excellence and/or also brainstorm about a shared vision for Birck. FinFET inspired SiC power MOSFETs Abstract: Silicon carbide (SiC) emerged as a viable semiconductor material in the early 1990’s. The earliest wafers were small, but wafer size and material quality has improved steadily, and today 100 and 150 mm nearly-defect-free wafers are commercially available from several suppliers. SiC power diodes entered commercial production in 2001, and have accumulated over 150 billion hours in the field with a failure rate 10x lower than silicon diodes. SiC MOSFETs entered production in 2011, and MOSFET sales recently surpassed $60 million per year. In spite of their progress, SiC power devices are still far from their theoretical limits of performance. This is especially true of power MOSFETs designed for the application rich space below 1 kV. The on-resistance of these SiC MOSFETs is currently limited by two elements: channel resistance due to the low mobility of electrons in the inversion layer, and substrate resistance. To make significant progress it is necessary to address both elements. In this talk, I will describe some of the innovative solutions we are pursuing that address both of these limitations. We reduce channel resistance by applying a “tri-gate” (3G) concept to power devices for the first time. The tri-gate geometry is used in 22 nm silicon CMOS technology to suppress short-channel effects. In SiC we use the 3G geometry for an entirely different reason: to increase the current-carrying width of the MOSFET channel without increasing the surface area. Using modifications of existing fabrication technology, the 3G structure can reduce MOSFET channel resistance by as much as an order-of-magnitude, without assuming any increase in channel mobility or improvement in interface quality. We reduce substrate resistance by forming a “waffle substrate” structure as the last step in the fabrication process. The waffle structure provides needed mechanical support, while reducing the resistance by as much as 5x below that of a thinned substrate alone. Please find below the BNC Spring Faculty Seminar Series schedule.

BNC Faculty Seminar Series - Presenter: Dallas Morisette - Thurs., 3/12 @ 12noon in BRK 2001
by Turner, Jaime J 09 Mar '20

09 Mar '20

Dear all, Dallas Morisette<https://engineering.purdue.edu/ECE/People/ptProfile?resource_id=77034&_ga=2…>, Research Assistant Professor of Electrical and Computer Engineering will present this week’s faculty seminar series, Thursday, 3/12 @ 12pm (lunch provided) in BRK 2001. The first half will be an overview of research and the remainder will be open for questions and high-level discussion of collaboration opportunities that can lead to future center of excellence and/or also brainstorm about a shared vision for Birck. FinFET inspired SiC power MOSFETs Abstract: Silicon carbide (SiC) emerged as a viable semiconductor material in the early 1990’s. The earliest wafers were small, but wafer size and material quality has improved steadily, and today 100 and 150 mm nearly-defect-free wafers are commercially available from several suppliers. SiC power diodes entered commercial production in 2001, and have accumulated over 150 billion hours in the field with a failure rate 10x lower than silicon diodes. SiC MOSFETs entered production in 2011, and MOSFET sales recently surpassed $60 million per year. In spite of their progress, SiC power devices are still far from their theoretical limits of performance. This is especially true of power MOSFETs designed for the application rich space below 1 kV. The on-resistance of these SiC MOSFETs is currently limited by two elements: channel resistance due to the low mobility of electrons in the inversion layer, and substrate resistance. To make significant progress it is necessary to address both elements. In this talk, I will describe some of the innovative solutions we are pursuing that address both of these limitations. We reduce channel resistance by applying a “tri-gate” (3G) concept to power devices for the first time. The tri-gate geometry is used in 22 nm silicon CMOS technology to suppress short-channel effects. In SiC we use the 3G geometry for an entirely different reason: to increase the current-carrying width of the MOSFET channel without increasing the surface area. Using modifications of existing fabrication technology, the 3G structure can reduce MOSFET channel resistance by as much as an order-of-magnitude, without assuming any increase in channel mobility or improvement in interface quality. We reduce substrate resistance by forming a “waffle substrate” structure as the last step in the fabrication process. The waffle structure provides needed mechanical support, while reducing the resistance by as much as 5x below that of a thinned substrate alone. Please find below the BNC Spring Faculty Seminar Series schedule.

Dear all, A gentle reminder that Shriram Ramanathan<https://shriram-ramanathan.org/?_ga=2.120580936.1380123278.1583157462-12224…>, Professor of Materials Engineering will present this week’s faculty seminar series, TODAY Thursday, 3/5 @ 12pm (lunch provided) in BRK 2001. The first half will be an overview of research and the remainder will be open for questions and high-level discussion of collaboration opportunities that can lead to future center of excellence and/or also brainstorm about a shared vision for Birck. Natural and Artificial Intelligence Abstract: About a decade ago, Toshiyuki Nakagaki et al stunned the scientific world by demonstrating that non-neural organisms can predict periodic events, reminiscent of the Egyptian civilization evolving around the flooding of the river Nile. More recently, studies on Asian monkeys in Khao Sam Roi Yot National Park in Thailand have shown that mastering tool-use can affect maturation of shellfish (prey). Such observations in nature force a fundamental re-think of how to design hardware for sustainable AI. I will discuss some ideas on electronic materials synthesis inspired by evolutionary dynamics and their potential relevance in neuromorphic computing.
