Abstract

See full text

A manufacturing method of a semiconductor device comprising the steps of: affixing a die attach film and a dicing film to a back surface of a semiconductor wafer: thereafter dicing the semiconductor wafer and the die attach film to divide the semiconductor wafer into a plurality of semiconductor chips: thereafter pulling the dicing film from the center toward the outer periphery of the dicing film with a first tensile force to cut the die attach film chip by chip; and thereafter picking up the semiconductor chips together with the die attach film while pulling the dicing film from the center toward the outer periphery of the dicing film with a second tensile force smaller than the first tensile force.
