Patent ID: 8647964

Claim:
A method comprising: (1) forming a film on a first substrate, where the film comprises: (I) a curable adhesive composition, (II) a degradation agent; and optionally one or more components selected from (III) a solvent, (IV) an inhibitor, (V) a filler, (VI) a treating agent, (VII) a spacer, (VIII) an adhesion promoter, (IX) a surfactant, (X) a colorant, and (XI) an optical brightener; optionally (2) heating the product of step (1), (3) applying a second substrate to the film, where at least one of the first substrate and the second substrate is a semiconductor wafer, (4) curing the film to form a cured film, (5) processing the semiconductor wafer, (6) degrading the cured film by heating, optionally (7) removing residue from the semiconductor wafer with a solvent, (8) separating the first substrate and the second substrate, and optionally (9) removing residue from the semiconductor wafer with a solvent and/or an etching solution.
