Abstract:
1. A dicing tape-integrated film for semiconductor back surface comprising: a dicing tape comprising a base material and a pressure-sensitive adhesive layer on the base material; and a film for flip chip type semiconductor back surface, which is provided on the pressure-sensitive adhesive layer, wherein the pressure-sensitive adhesive layer comprises at least a cured portion and an uncured portion, and wherein the dicing tape-integrated film for semiconductor back surface satisfies a relation: r1<r2<r3, wherein r1 is a diameter of a semiconductor wafer; r2 is a diameter of the cured portion in the pressure-sensitive adhesive layer, which corresponds to the film for flip chip type semiconductor back surface or a semiconductor wafer-attaching part in the film for flip chip type semiconductor back surface; and r3 is a diameter of the film for flip chip type semiconductor back surface or the semiconductor wafer-attaching part in the film for flip chip type semiconductor back surface.
