Pieces need a carrier wafer; Isotropic Etching
3 Probe Heads for different cleanliness groups.
To maintain cleanliness level, cleans of both the chamber and wafers are required 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
4" wafers; can be adopted to do 6" or 8" wafers; pieces need to be bonded to carrier wafers
