[labnetwork] Cleanroom training policies + COVID guidelines

Wed Dec 16 18:06:05 EST 2020

For all training at MTU I started generating complete training videos the user could study and be quizzed on. The students could also use this while using the system and zooming with me if required. I know this does not work for all systems, but helped get some users trained with complete isolation. Also might not work for complete novices.

Our previous protocol usually involved an initial training session (sometimes grouped with 1-2 others trainees) to see the equipment use through a typical run. This was followed by a check-off session supervised by the tool owner with the user running one of their own samples through the system. This required a lot of close contact of course and was sometimes unnecessarily complex.

> For the check off we have had the users run a “standard” process rather than their own sample. They are given a rough checklist to follow with break points on any steps where the staff member would need to physically check any positioning, parameters, etc. While the user is running the staff is usually within sight distance and available if needed, but is otherwise hands-off. Whenever a break point is reached the user calls over the staff member for a check and then the process continues.

Training on our maskless aligner, evaporators, PECVD, and etchers, have all worked out well. Things like photolithography, wet chemical work, SEM, etc. have been slower to turn on because they often require much more interaction and are more difficult while remaining distanced. We have considered doing live zoom/phone calls to enable remote communication live during a training or checkoff but have not implemented it to a large degree yet.

It is quite loud and we have found that even routine conversations end up being shouted from a close distance in order to effectively be heard. That is why we have moved as much as we can remotely and also tried to even limit interactions or question & answer during the in-person checkoff. The beneficial (in my opinion) side effect of this is that it forces the users to be much more self-reliant during the checkoff. Instead of simply turning to the staff member and being guided through the process they must know or be able to find the information they need themselves. In my opinion this will make them much more effective lab users overall since the vast majority of their processing time is going to be independent of staff intervention.

It would be useful to understand what others are doing so a few questions for the group – Are you providing in-lab training? If so, what accommodations are in place? Do you have defined metrics for tightening or loosening restrictions?

This has worked well since we re-opened in the middle of June; the face mask is meant to help with the virus and the beard cover with the lab cleanliness. During training both the trainer and the trainee also wear face shields (the type we use for acid work at the fume hoods).
