Pre-clean	RF Ar clean
Layer thickness	10Å to about 2000Å
Deposition rate	From 0.4 Å/s up to about ~2Å/s
Comment	Recommended for unexposed e-beam resist
Allowed substrates	Silicon wafers Quartz wafers Pyrex wafers
Allowed materials	Silicon oxide Silicon (oxy)nitride Photoresist PMMA Mylar SU-8 Metals
