parylene adhesion on Silicon

Reza,
     Two ways. One total vacuum dehydration before applying any one of a
number of silane precursors for Parylene adhesion.  Two replace Parylene
with double silane coating that is far superior to Parylene for
protection.  Contact me directly for technical papers and reports.

Subject: [mems-talk] parylene adhesion on Silicon

Hi,

I have a silicon wafer with a 5 um parylene on it which is a chemical
protector. The package will operate at 170C and up to 300 psi in a basic
solution. Due to poor adhesion of parylene, the liquid penetrates under
the parylene film. I am wondering how I can increase the adhesion.

Your advise will be appreciated.

Thnaks,
Reza
