I used STR 1045 negative PR ( at 2250rpm: thickness 6um) to
lift-off 400nm Au with PR stripper at 70 degrees C.

Works great.

Hope this helps.

Dear All,

does anybody has experience in a metal-lift-off-process? I am searching
for a resist working fine for soft metal with a thickness of about
300nm. May be you can advise me either negative or positive resists.

I would appreciate any help,
Thanks in advance,

Bernd Krueger
