Patent ID: 7989320

Claim:
A method of die bonding comprising the steps of: providing a structure comprising a wafer substrate separated from a carrier base by a curable adhesive layer in a non-cured state positioned between the carrier base and the wafer substrate; laser machining through the wafer substrate and the adhesive layer to form a singulated die with an attached singulated adhesive layer, the laser machining including controlling machining parameters of a laser beam in which a first laser machining profile is used to cut through the wafer substrate and a second laser machining profile is used to cut through the adhesive layer, the second laser machining profile being different from the first laser machining profile and adapted to inhibit delamination of the adhesive layer from the carrier base with the adhesive layer in the non-cured state; performing a first curing process on the attached singulated adhesive layer to release the singulated die and the attached singulated adhesive layer from the carrier base and thereby enable the singulated die and the attached singulated adhesive layer to be removed from the carrier base and placed on a die pad; and performing a second curing process to adhere the singulated die to the die pad.
