Patent ID: 8617930

Claim:
A method of producing a semiconductor device, comprising: Iâ€²) a step of sticking a dicing tape integrated adhesive sheet onto a semiconductor wafer, wherein the dicing tape integrated adhesive sheet is formed by lamination of an adhesive sheet and a dicing tape; and the adhesive sheet comprises a polymer component, an epoxy resin and a filler, wherein the breaking strength of the adhesive sheet in a B-stage state is from 0.1 to 10 Mpa at 25Â° C.; and the breaking elongation of the adhesive sheet is from 1 to 40% at 25Â° C.; and the dicing tape comprises a substrate layer made of a polyvinyl chloride; and II) a step of rendering the semiconductor wafer permissible to be cut by a method of half cut dicing or stealth dicing, with steps Iâ€² and II being carried out in order of Iâ€²-II or II-Iâ€²; and further comprising: III) a step of cutting the semiconductor wafer and the adhesive sheet of the dicing tape integrated adhesive sheet by applying external force of the expand amount being more than 25 mm and 30 mm or less wherein the expand amount is measured as the height of the elevation of the dicing tape being pushed up at both of its ends, thereby yielding adhesive-sheet-stuck semiconductor chips which are individual pieces; and IV) a step of bonding the adhesive-sheet-stuck semiconductor chips onto a semiconductor-chip-mounting support member.
