Abstract:
1. A method of producing a semiconductor device, comprising: I′) the 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 filler is included in the adhesive sheet in an amount of 35 to 60% by weight, of the total weight of the adhesive sheet; and the dicing tape comprises a substrate layer made of a vinyl chloride or polyolefin; and II) the step of rendering the semiconductor wafer permissible to be cut a method of half cut dicing or stealth dicing, with steps I′ and II being carried out in order of I′-II or II-I′; and further comprising: III) the 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, thereby yielding adhesive-sheet-stuck semiconductor chips which are individual pieces; and IV) the step of bonding the adhesive-sheet-stuck semiconductor chips onto a semiconductor-chip-mounting support member.
