About PPE: alcohol wipe down before and after each use. In addition, face shields will be placed in the steamer for 1 1/2 hours. Aprons will be user owned, not shared.
This wet bench is used for wet chemical (corrosives) processing of standard and non-standard (flexible) materials like glass, wafer pieces, devices with gold or non-standard metals. It is also used for non-CMOS compatible processing, such as KOH etching. With the appropriate, dedicated glassware, KOH cleanup can be done to decontaminate wafers for later CMOS-compatible processing.

Steps to become a tool user
-
Become a member of SNF.
- Read the relevant operating procedures:
- Wet Bench Flexcorr 1
- Wet Bench Flexcorr 3
- View the Plastic Tweezers Cleaning (9 minutes) movie.
- Shadowing: Contact a qualified user of the tool to arrange to ‘shadow’. It would be best to find someone who has used the system often. If you don’t know of anyone, you may check reservations or history to find a qualified user. You may also contact the Discussion Lists. We recommend that you be with the lab member for the full time while operating the tool and ask lots of questions during the shadowing. You may have to shadow a qualified user more than one time to be comfortable with the tool.
Please follow the instructions on this form: SNF Training Shadowing Form - "All Litho" class is required before training on any of the lithography tools. Please send an email to all-litho-training@lists.stanford.edu to sign up for the All Litho class. Read more here: All Litho class.
