Abstract

Disclosed is an adhesive composition which includes (a) an epoxy resin, (b) a curing agent and (c) a polymer compound incompatible with said epoxy resin, and further optionally includes (d) a filler and/or (e) a curing accelerator. Also disclosed are a process for producing an adhesive composition, including mixing (a) the epoxy resin and (b) the curing agent with (d) the filler, followed by mixing the resultant mixture with (c) the polymer compound incompatible with the epoxy resin; an adhesive film including the above-mentioned adhesive composition formed into a film; a substrate for mounting a semiconductor including a wiring board and the above-mentioned adhesive film disposed thereon on its side where chips are to be mounted; and a semiconductor device which includes the above-mentioned adhesive film or the substrate for mounting a semiconductor.
