The following is a list of equipment where 4 inch round substrates are allowed.
To maintain cleanliness level there are cleans required for both the chamber and wafers prior to processing -
Substrates in clean category: Pre-Diffusion Clean
For semi-clean substrates: Standard Metal Clean (SRS100 + PRS1000) . Run Chamber clean (no dummies) and conditioning with clean dummies prior to run
CO2 drying after release of micromachined devices
Two programs: Singe and HMDS prime or Singe only. No Resist allowed!
For more than 300nm deposition, please contact Gabe Catalano <gcatalano@stanford.edu> in advance
Resist should have been removed
No resist allowed. Resist should have been removed at the wbclean_res-piranha.
For LOL2000 bake or bakes which are not allowed in the other ovens and need higher temperatures, up to 200C, programmable.
Manual wet etching of non-standard materials. Hot plate available. GaAs allowed in personal labware only.
Typically used for sputter etching; Single wafer, direct load system; wafers/ pieces can be directly placed on electrode
Convection in N2. Cure. Programmable.
Automatic HMDS, Resist spinning, and Bake. AZ5214IR Image Reversal.
Manual wet etching of non-standard materials. Hot pots available. GaAs allowed in personal labware only
Single wafer tool with auto loading from a cassette. Pieces need a pocket carrier wafer for transport. Wafers heated by lamps.
Bakes wafers with resist after the development, called post-bake.
No resist allowed. Resist should have been removed at the wbclean_res-piranha
