Abstract
The present invention relates to a film for flip chip type semiconductor back surface to be formed on a back surface of a semiconductor element flip chip-connected onto an adherend, in which the film for flip chip type semiconductor back surface before thermal curing has, at the thermal curing thereof, a volume contraction ratio within a range of 23° C. to 165° C. of 100 ppm/° C. to 400 ppm/° C.
