Patent ID: 8563405

Claim:
A method for manufacturing a semiconductor device, the method comprising: forming an adhering layer between a carrier substrate and a first pieced segment of wafer and a second pieced segment of wafer, respectively, wherein the first pieced segment of wafer includes a first active surface, a first back surface opposite the first active surface, and a first bonding pad positioned on the first active surface, wherein the second pieced segment of wafer includes a second active surface, a second back surface opposite the second active surface, and a second bonding pad positioned on the second active surface, and wherein the adhering layer is patterned such that the adhering layer covers less than an entirety of the first active surface or the second active surface; forming a via in the first pieced segment of wafer, wherein the via is electrically connected to the first bonding pad; and separating the first pieced segment of wafer and the second pieced segment of wafer from the carrier substrate.
