Hi, Guys, I am trying to make a thin-film of PDMS, having some through patterns on it; i.e., the PDMS film will have many holes through the entire thickness of the film. This PDMS film will later be attached onto another thick, patterned PDMS layer, to complete the system. I know people have used RIE to etch PDMS. Is there any easier way to accomplish this? Thanks a lot. -- Best Regards, Shawn
