Abstract:
1. An adhesive bonding sheet having an optically transmitting supporting substrate and an adhesive bonding layer, and capable of being used in both a dicing step and a semiconductor element adhesion step, wherein the yield elongation of the supporting substrate at room temperature is 20% or more, wherein the adhesive bonding layer comprises (a) a polymer component having a weight average molecular weight of 100,000 or more including functional groups, (b) an epoxy resin, (c) an epoxy resin curing agent, (d) a photoreactive monomer, wherein the Tg of cured material of the photoreactive monomer, obtained by ultraviolet light irradiation, is 250° C. or more, and (e) a photoinitiator, and wherein the photoreactive monomer is dipentaerythritol hexacrylate or ethoxylated isocyanuric acid triacrylate.
