Patent ID: 7488539

Claim:
A dicing and die bonding sheet comprising a substrate, a pressure sensitive silicone adhesive layer provided on the substrate, and an adhesive layer provided on the pressure sensitive silicone adhesive layer, said latter adhesive layer being prepared from an adhesive composition comprising: 5 to 60 wt % of (A) a polyimidesilicone resin; 5 to 60 wt % of (B) an epoxy resin having a softening point of 80° C. or lower; 0.001 to 20 wt % of (C) dicyandiamide; 20 to 70 wt % of (D) spherical silica having an average diameter of 0.1 to 10 μm; and 5 to 30 wt % of (E) spherical fine particles of silicone rubber composite, wherein said wt % is based on a total weight of the adhesive composition, wherein a 180-degree peel force measured by peeling off the pressure sensitive adhesive layer from the adhesive layer provided on the pressure sensitive silicone adhesive layer ranges from 0.05 to 1.0 N/25 mm.
