With the install of the new spinners, materials will be segregated by spinner. Please see the following page for what spinner you will need to use for a particular material once the spinners are reclasiffied.
The categories and allowed chemical/spinner pairings are still being refined and your feedback would be appreciated. Please comment on this page (at the page bottom) with any questions, comments, or feedback.

Cleaning Solvents
As needed for removal of approved resists. Any Litho hood approved solvents may be used as appropriate.
Specifically not permitted in Cleanroom
Silicones/PDMS
Reason: These are impossible to remove chemically once cured, and are not used for lithography processes. Email Joon Park for information on proper curing of HMDS outside the cleanroom.
- Sylgard 182
- Sylgard 184
100% HMDS
Reason: 100% HMDS is extremely hazardous for both skin contact and inhalation. Additionally, in air, it degrades into ammonia upon evaporation, which crosslinks common photoresist. It gives sub-optimal results compared to diluted (80% PGMEA + 20% HMDS) solutions, or SurPass. Contact Justin Wirth with any questions.
- HMDS/Hexamethyldisilazane
