CARRIER FILM FOR SEMI-CONDUCTOR WAFER PROCESSING

A carrier film includes an adhesive layer, a core layer, and a release layer. The adhesive layer includes a hydrogenated styrene block copolymer having a storage modulus (G′) of less than or equal to 400 kPa at 25° C., and a first polyolefin elastomer. The core layer includes a second polyolefin ela...
