Az5214, Shipley 1818, Az4620..., are good for liftoff, depending on you
feature size and profile height. We have done with them for many times
without any problem. Let me know if you have any questions.

Good luck,

Subject: [mems-talk] Gold patterning using lift off on substrates

I was interested if anyone had a particular resist they used for a lift off
process of Cr/Au pads on glass slides or on PDMS.

Process that I would like to perform:

1) Clean substrate
2) Dry, perhaps HMDS
3) Spin PR (What PR is good?)
4) Develop
5) Evaporate Cr/Au on substrate
6) Lift off the PR to expose just substrate and Cr/Au

Has anyone tried this or have suggestions?

I don't know what PR is good for glass slides or PDMS
