Abstract:
1. A process for producing a semiconductor device, comprising steps of: laminating an integrated dicing tape-adhesive sheet and a wafer, and then cutting the wafer and the dicing tape-adhesive sheet, to give an adhesive-equipped semiconductor chip consisting of a semiconductor chip and an adhesive sheet, wherein the adhesive sheet has a thickness of 10 to 250 μm and consists essentially of (a) 100 parts by weight of a resin comprising 15 to 40 wt% of an acrylic rubber and 60 to 85 wt% a thermosetting component containing an epoxy resin as a main component, and (b) 40 to 180 parts by weight of a filler that has a Mohs' hardness of 3 to 8, the adhesive sheet being directly in contact with the semiconductor chip, and bonding the adhesive-equipped semiconductor chip to a wire-equipped semiconductor chip with a load applied so as to fill in with adhesive of the adhesive sheet irregularities due to a wire of the wire-equipped semiconductor chip.
