Hi Paik,
I used sputter process on Pyrex for my evaluations. Direct gold has good
initial adhesion. Once you try to increase the thickness it results in poor
adhesion. You need to do a lot of surface treatment on the Pyrex to get a
good adhesion. Try a layer of Ti (1000A) and then gold. This will help.
Platinum sputter target exists. Price depends on the target size. Check with
BPS and other material suppliers.
Regards Gautham. V
