Frank,

         We have some experience with making microfludic channels and
doing a bond as you have described. Please call me so we can discuss it
in detail.

Subject: [mems-talk] Glass or Silicon Bonding to Polymer

Dear MEMS-Colleagues,

For a microfluidic application, we want to bond a glass plate to a
Silicon
wafer
with a photo-patterned polymer layer inbetween.
We are free (within limits) to choose the polymer, which can be spin-on
or
laminate. We can also apply it to either the glass or the Silicon (or
both)
and
we can add additional layers (Oxide, SiN, metal) on either.
Do you have experience with similar processes or do you know where to
find
further information? Any hint is welcome.
Please note that we want to bond after patterning (and thus
cross-linking)
the
polymer.

Greetings,
        Frank Berauer

Hi Cormac,
Try resinoid blades with 30-45u diamond. blade spped (on 21/4" blade)
