摘要:
Disclosed is an adhesive sheet for inspection, which is obtained by arranging an adhesive layer on a base film. The base film and the adhesive layer are electrically conductive, and an electrically conductive path is formed between the base film and the adhesive layer. Consequently, an inspection for electrical conduction of a semiconductor wafer or a semiconductor chip obtained by dicing a semiconductor wafer can be performed while the semiconductor wafer or the semiconductor chip is bonded to the adhesive sheet. In addition, this adhesive sheet for inspection enables to prevent deformation (warping) or breakage of a semiconductor wafer or generation of cracks or scratches on the back surface of the semiconductor wafer during the inspection.
