Patent ID: 7244495

Claim:
A dicing/die bonding adhesion tape comprising a substrate, a silicone adhesive layer directly on the substrate, which silicone adhesive layer is formed by heat curing a silicone adhesive composition comprising a heat curable chain-like organopolysiloxane and an organopolysiloxane copolymer resin composed of R 1 3 SiO 1/2 units and SiO 2 units wherein R 1 is a substituted or unsubstituted monovalent hydrocarbon radical and wherein the molar ratio of R 1 3 SiO 1/2 units to SiO 2 units is from 0.5 to 1.5, and a bonding layer directly on the silicone adhesive layer, wherein the tack strength between the silicone adhesive layer and the bonding layer is 0.2 to 2.0 N/25 mm, and said bonding layer is formed of an bonding composition comprising (A) a polyimide resin, (B) an epoxy resin, and (C) an epoxy resin curing catalyst.
