Authorized Materials

Summary of material constraints

Lab members wishing to introduce new materials into this system must first obtain authorization from staff. New material requests must be initiated by submitting a Process Review Request form.

Non compliance will result in loss of member privileges

Authorized Substrates & Thin Films

System can handle 3", 4" and 6" diameter wafers ONLY
Silicon substrates ONLY, which may be coated with:

alumina (Al2O3)
silicon nitride
silicon dioxide
amorphous silicon and polysilicon
GaAs and InAs
thin films of: Ti, Al, Ni, Cr, Au, Pt, Ge
if any other materials are present on your samples, CONTACT STAFF BEFORE PROCEEDING

PROHIBITED Films

The possibility of introducing the following films has been studied. Our research has concluded that the risk of chamber contamination is too high. Thus, these materials are NOT ALLOWED in this system:

ZnSe
Se
Bi₂Te₃
