With the install of the new spinnersSpinner 3, 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 reclasiffiedreclassified.

The categories and allowed chemical/spinner pairings are still being refined and your feedback would be appreciated. Email jcwirth@purdue.edu Please comment on this page (at the page bottom) with any questions, comments, or feedback.

    Resist Removal Solvents

    As needed for removal of approved resists. Any Litho hood approved solvents may be used as appropriate.

    Solvents

    • Acetone
    • Methanol
    • IPA

    • PGMEA (AZ EBR Solvent, Microposit Thinner P)

    Approval for new/additional chemicals:

    Additional materials must be pre-approved, and material must:

    A) Be

    for use in an EBL or NIL system

    completely removed in acetone if dried.
    B)

    Be spun in low volumes

    Not polymerize in contact with acetone, PGMEA, or water.
    C)

    Be removable with an approved solvent or alkaline

    Not have vapors which harden resist (NMP, Ammonia, toluene, cholorbenzene) or dope substrates.


    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.
