Patent ID: 8664082

Claim:
A method for preparing a substrate for temporarily bonding to a wafer, the method comprising the steps of: applying a first adhesive layer on the substrate and/or the wafer, wherein the first adhesive layer is applied in such a way that the first adhesive layer is disposed annularly between the substrate and the wafer in the edge region of the wafer and applying a second adhesive in the region situated within the annular first adhesive layer, wherein said second adhesive loses its adhesive properties at a temperature that is lower than a temperature at which the first adhesive layer loses its adhesive properties, and wherein the foregoing steps are performed in a manner such that the substrate is thereby configured to temporarily bond to the wafer and configured so that a treatment of only the annular edge region of the substrate and/or the wafer is required to reduce the adhesion of the first adhesive layer in order to separate the substrate and the wafer.
