Patent ID: 10858547

Abstract:
Provided is a film for manufacturing a semiconductor part in which an evaluation step accompanied with a temperature change, a segmenting step, and a pickup step can be commonly performed, a method for manufacturing a semiconductor part, a semiconductor part, and an evaluation method. The film includes a base layer, and an adhesive layer disposed on one surface side of the base layer, wherein the ratio RE (=E′(160)/E′(−40)) of the elastic modulus of the base layer at 160° C. to the elastic modulus of the base layer at −40° C. is RE≥0.01, and the elastic modulus E′(−40) is 10 MPa to less than 1000 MPa. The method includes bonding the adhesive layer to a back surface of a semiconductor wafer, separating the semiconductor wafer into segments to obtain semiconductor parts, and separating the semiconductor parts from the adhesive layer, and includes a step of evaluating.
