Patent ID: 7491625

Claim:
A method of handling a bumped integrated circuit wafer that has a multiplicity of integrated circuit dice formed therein, each integrated circuit die including an active surface and a back surface, the active surface having a multiplicity of bond pads, the bond pads having solder pads thereon, the method comprising: adhering a back surface of the bumped wafer to a first releasable mount tape; singulating the wafer with the wafer secured to the first releasable mount tape to provide a multiplicity of individual bumped dice, wherein the singulation does not cut fully through the first releasable mount tape and wherein the back surfaces of the singulated dice remain adhered to the first releasable mount tape; adhering the bumped active surfaces of the singulated dice to a second tape with the first releasable mount tape still adhered to the back surfaces of the dice; and releasing the first releasable mount tape and removing the released mount tape from the back surfaces of the dice after adhering the bumped active surfaces of the singulated dice to the second tape thereby leaving the back surfaces of the dice exposed and facing upwards with the bumped active surfaces of the dice adhered to the second tape.
