Hi all,
I am currently interested in wet etching approximately 1-2 microns of
polyimide (Dupont PI2545), which I use as a sacrificial layer in MEMS
applications. A fast, dry etch tends to generate stress in the
structural layers, and hence we seek a method of slowly and gently wet
etching polyimide. If anyone has previously done this, or knows of an
etch recipe/product I can use for this purpose, I would like to hear
from you.
Any help would be greatly appreciated.

Regards,

Conor O'Mahony
