Post-CMOS processing of a state-of-the-art CMOS chip

[Gael Close]

Dear lab members,

I would like to know if anyone has some experience in the fabrication
of micro-structures on top of a state-of-the-art CMOS chip from a
foundry.

Specifically, has anyone ever contacted a post-frabricated
devices/wires to a underlying CMOS  circuitry.

I have browsed the litterature, and it seems to be rather common in
the MEMS community. It would be very helpful if one of you is willing
to share his/her experiences.

Thank you,
-Gael
