The present invention relates to a film for back surface of flip-chip semiconductor, which is to be formed on a back surface of a semiconductor element flip-chip connected onto an adherend, wherein an amount of shrinkage of the film for back surface of flip-chip semiconductor due to thermal curing is 2% by volume or more and not more than 30% by volume relative to a total volume of the film for back surface of flip-chip semiconductor before the thermal curing. According to the film for back surface of flip-chip semiconductor according to the present invention, since it is formed on the back surface of a semiconductor element having been flip-chip connected onto an adherend, it fulfills a function to protect the semiconductor element. In addition, in the film for back surface of flip-chip semiconductor according to the present invention, since an amount of shrinkage due to thermal curing is 2% by volume or more relative to a total volume of the film for back surface of flip-chip semiconductor before the thermal curing, a warp of a semiconductor element to be generated at the time of flip-chip connecting the semiconductor element onto an adherend can be effectively suppressed or prevented. |
