I wonder if a PDMS bond between two wafers will withstand a KOH etch, or
will the interface fail?

Hello,

I wanted to know if anyone of you has an experience with performing
EDP/KOH etch of a Si wafer with PDMS or photopatternable silicone WL
5150 patterned on the back side. Does the EDP/KOH etch damage the PDMS
or the photopatternable silicone?

Thank you very much,
