Patent ID: 8314008

Claim:
A method of mounting a MEMS integrated circuit on a substrate, said method comprising the steps of: (a) providing a film frame tape supported by a wafer film frame, said film frame tape having a plurality of MEMS integrated circuits releasably attached via respective frontsides to said film frame tape, wherein a backside of each MEMS integrated circuit has a surface oxide layer; (b) treating the surface oxide layer with liquid ammonia; (c) positioning a substrate at the backside of one of said MEMS integrated circuits; (d) positioning a bonding tool on a zone of said film frame tape, said zone being aligned with said MEMS integrated circuit; and (e) applying a bonding force from said bonding tool, through said film frame tape and said MEMS integrated circuit, onto said substrate, thereby bonding said backside of said MEMS integrated circuit to said substrate.
