Patent ID: 7883991

Claim:
A method of fabricating a stacked device, comprising: providing a wafer having a first surface and a second surface opposite to the first surface, wherein the first surface is coated with a first adhesive layer; providing a carrier coated with a second adhesive layer, exposing the edge zone of the carrier; bonding the first surface of the wafer to the carrier through the first adhesive layer and the second adhesive layer, wherein the edge zone of the carrier is covered by the first adhesive layer; thinning the wafer from the second surface, forming a thinned wafer; bonding a plurality of dies onto the thinned wafer; removing the first adhesive layer adjacent the edge of the thinned wafer, exposing the edge zone of the carrier and the second adhesive layer adjacent the edge zone of the carrier; applying a light-form energy to decompose the second adhesive layer; detaching the carrier from the wafer; and removing the first adhesive layer remaining on the first surface of the wafer.
