Patent ID: 8703584

Claim:
A process for producing a semiconductor device comprising: attaching a workpiece onto a wafer adhesion layer of a film for flip chip type semiconductor back surface of a dicing tape-integrated film for semiconductor back surface, dicing the workpiece to form a chip-shaped workpiece, peeling the chip-shaped workpiece from a pressure-sensitive adhesive layer of the dicing tape together with the film for flip chip type semiconductor back surface, and fixing the chip-shaped workpiece to an adherend by flip chip bonding, wherein the dicing tape-integrated film for semiconductor back surface comprises the dicing tape including a base material and the pressure-sensitive adhesive layer provided on the base material; and the film for flip chip type semiconductor back surface provided on the pressure-sensitive adhesive layer, wherein the film for flip chip type semiconductor back surface has a multilayered structure including the wafer adhesion layer and a laser mark layer, wherein the wafer adhesion layer is formed of a resin composition containing a thermosetting resin component and a thermoplastic resin component in an amount of less than 30% by weight relative to the whole amount of resin components, wherein the laser mark layer is formed of a resin composition containing a thermoplastic resin component in an amount of 30% by weight or more relative to the whole amount of resin components and a thermosetting resin component, wherein the wafer adhesion layer has a thickness of 1 to 50 μm, the laser mark layer has a thickness of 1 to 50 μm and the film for flip chip type semiconductor back surface has a thickness of 5 to 500 μm, and wherein a ratio of the thickness of the film for flip chip type semiconductor back surface to the thickness of the dicing tape is within a range of 150/50 to 3/500.
