Claim Text:
1. A method of manufacturing a flip-chip type semiconductor device comprising: a step A of laminating on a semiconductor wafer a film for the backside of a flip-chip type semiconductor, in which the film is to be formed on the backside of a semiconductor element that is flip-chip connected onto an adherend; a step B of dicing the semiconductor wafer; and a step C of laser marking the film for the backside of a flip-chip type semiconductor, wherein the film for the backside of a flip-chip type semiconductor in the step C is uncured, and formed from a resin composition containing an epoxy resin and a phenol resin, and the total amount of the epoxy resin and the phenol resin is 10 to 25 parts by weight to 100 parts by weight of the resin composition.
