Hello Dr. Bondavalli,
if I understand your question correctly you might try Imprint Patterning, a way
to pattern holes and channels at the same time, in thermoplastics (& thermosets,
etc.). No photoresists required. If you are going submicron it's nanoimprinting.
Much public info. is available on the Web, I'm sending you some of it
separately.

new and advantageous method of forming advanced circuitry"

and photopatternable resin


  Hi all MEMS experts,        I'd like to know if a photopatternable and
thermoplastic resin exists.    Bye.
