Abstract:
1. A method of bonding an integrated circuit to an adhesive substrate, said integrated circuit being one of a plurality of integrated circuits each having a respective frontside releasably attached to a film frame tape supported by a wafer film frame, said method comprising the steps of: (a) selecting one of said integrated circuits for bonding to said adhesive substrate; (b) positioning the adhesive substrate at a backside of said selected integrated circuit; (c) positioning a bonding tool on a zone of said film frame tape, said zone being aligned with said selected integrated circuit; and (d) applying a bonding force from said bonding tool through said film frame tape and said selected integrated circuit onto said adhesive substrate, thereby bonding said backside of said selected integrated circuit to said substrate, wherein a backside oxide layer of each of said integrated circuits is pre-treated with liquid ammonia prior to bonding.
