Abstract

We have developed novel mask materials against HF Vapor release for MEMS/NEMS. Parylene-C has a tolerant material against moisture pass, and then, thin aluminum layer has also tolerant against HF vapor. We combined them together for high tolerance and we have successfully obtained completely non-etched silicon oxide layer under HF vapor exposure by Parylene/Al/Parylene sandwich structure.
