Dear All,

Has anyone attempted to create a two layered structure using Su-
2075 where the top layer OVERHANGS the bottom layer?

I am trying to do this using conventional photolithography methods
but without success.

Because the Su-2075 is so transparent, it is difficult to judge the
exact exposure time so that the top layer is not crosslinked all the
way down to the wafer surface.

A sales rep from one of the Su-2075 manufacturers thinks this is
impossible.

Best regards.
