Patent ID: 8852391

Claim:
A temporary bonding method comprising: providing a stack comprising: a first substrate having a back surface and a device surface, said device surface having a peripheral region and a central region; a second substrate bonded to said first substrate, said second substrate having a carrier surface, a backside surface, and an outermost edge defining the periphery of the second substrate, said carrier surface having a peripheral region and a central region and comprising a surface modification, said carrier surface comprising surface-modified portions and non-modified portions, wherein said surface-modified portions have a low bonding surface; and a uniform bonding layer between said first substrate and said second substrate, said bonding layer being formed from a polymeric adhesive; and separating said first and second substrate using a peeling motion by applying a force to a portion of the periphery of said second substrate causing said second substrate to bend at an angle away from the stack, thereby separating said first substrate and second substrate.
