See full text

Novel adhesive compositions that can be used in the die attach process. The adhesives include a curable resin component, a curing agent, and a block copolymer additive. The block copolymer additive has a glass transition temperature of at least about 40° C. The block copolymer additive improves the affinity of the adhesive composition to a hydrophilic substrate, such as a silicon wafer, during the die pickup process. Also disclosed is an assembly which includes a hydrophilic substrate and a layer of adhesive and methods of producing the assembly.
