Patent ID: 8652938

Claim:
A thermally releasable sheet-integrated film for semiconductor back surface, which comprises: a pressure-sensitive adhesive sheet comprising a base material layer and a pressure-sensitive adhesive layer, and a film for semiconductor back surface formed on the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet, wherein the pressure-sensitive adhesive sheet is a thermally releasable pressure-sensitive adhesive sheet whose peel force from the film for semiconductor back surface decreases upon heating, wherein the film for semiconductor back surface has a thickness of 2 to 200 nm, a moisture absorbance of 1% by weight or less after the film semiconductor back surface is allowed to stand under an atmosphere of a temperature of 85° C. and a humidity of 85% RH for 168 hours, and a weight decrease ratio of 1% by weight or less after heating at 250° C. for 1 hour.
