Abstract:
The present invention provides a dicing tape-integrated film for semiconductor back surface, which includes: a dicing tape including a base material and a pressure-sensitive adhesive layer provided on the base material; and a film for flip chip type semiconductor back surface provided on the pressure-sensitive adhesive layer, in which the film for flip chip type semiconductor back surface has a multilayered structure including a wafer adhesion layer and a laser mark layer, the wafer adhesion layer is formed of a resin composition containing a thermosetting resin component and, as an optional component, a thermoplastic resin component in an amount of less than 30% by weight relative to the whole amount of resin components, and 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, as an optional component, a thermosetting resin component.
