Approval for new/additional chemicals:
Additional materials must be pre-approved, and material must:
A) Be completely removed in acetone if dried.
B) Not polymerize in contact with acetone, PGMEA, or water.
C) Not have vapors which harden resist (NMP, Ammonia, toluene, cholorbenzene) or dope substrates.

NIL Resists & Promoters
- NXR-3000

- Ormoprime 08 (Be extremely careful, may be impossible to remove with normal solvents)
Resist Removal Solvents
As needed for removal of approved resists. Any Litho hood approved solvents may be used as appropriate.
Approval for new/additional chemicals
Additional materials must be pre-approved, and material must:
A) Be for use in an EBL or NIL system.
B) Be spun in low volumes.
C) Be removable with an approved solvent or alkaline.
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
