The photoresist we use in my lab is Clariant AZ5209 (useable as
positive or negative photoresist, depending upon the processing).
Spinning at 4000 rpm gives you a .9um coating.

Does anyone know of other sources for photoresist, along with any
pricing info? Just about the only one I know of is the Seno resist
sold through Mega Electronics.
