Semiconductor photoresist process


Dear everyone,

After exposing and developing processes, I want to use the 1.6 micron photoresist layer as a mask to etch 1 micron silicon dioxide with RIE system. But I am not sure the 1.6 micron thickness of AZ 3612 Shipley photoresist can be strong enough for my etching process. Please help me with your experiences.

Thanks so much for your help.
