most polyimides in Si processing are designed to have a good adhesion to
Si. depends whether you want photosensitive or non-photosensitive one.
The three major suppliers whose products i've played with and found good
are hitachi, hoechst and ciba-giegy.
When you see the product catalagues, you'll see about a very big range and
hence its best to pick one up that suits your applications and processing
conditions best
Good luck,
