Claim:
1. A dicing-tape integrated film for a backside of a semiconductor having a dicing tape having a substrate and a pressure-sensitive adhesive layer formed on the substrate and a film for a backside of a flip-chip semiconductor formed on the pressure-sensitive adhesive layer of the dicing tape, wherein the film for the backside of a flip-chip semiconductor contains a coloring agent, the solubility of the coloring agent to toluene at 23° C. is 2 g/100 ml or less, and a difference between surface free energy E1 of the film for the backside of a flip-chip semiconductor and surface free energy E2 of the pressure-sensitive adhesive layer (E1-E2) is 10 mJ/m
