Patent ID: 8399338

Claim:
A dicing method for a semiconductor wafer comprising a semi-cured glue layer, comprising: applying a paste-type glue to a rear surface of a semiconductor wafer, and semi-curing said paste-type glue in the form of a sheet by heating or UV irradiation to form a semi-cured glue layer; bonding an adhesive sheet comprising a UV-curable adhesive layered on a substrate film to said semi-cured glue layer; subjecting said UV-curable adhesive to UV irradiation; and dicing said semiconductor wafer and said semi-cured glue layer bonded to said adhesive sheet, wherein said UV-curable adhesive comprises at least a (meth)acrylic acid ester polymer, a urethane acrylate oligomer having at least four vinyl groups, a UV polymerization initiator and a silicone graft polymer.
