Patent ID: 8704382

Claim:
A dicing tape-integrated film for semiconductor back surface, comprising: a dicing tape comprising a base material and a pressure-sensitive adhesive layer formed on the base material; and a film for flip chip type semiconductor back surface, which is to be formed on a back surface of a semiconductor element flip-chip connected on an adherend, wherein said film comprises a wafer adhesion layer and a laser marking layer, wherein the wafer adhesion layer has a light transmittance of 40% or more in terms of a light having a wavelength of 532 nm and the laser marking layer has a light transmittance of less than 40% in terms of a light having a wavelength of 532 nm, wherein the light transmittance is measured using the wafer adhesion layer and the laser marking layer having a thickness of 10 μm, and wherein the film is formed on the pressure-sensitive adhesive layer of the dicing tape in such a manner that the laser marking layer is laminated on the pressure-sensitive adhesive layer of the dicing tape.
