Patent ID: 8105878

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: (a) providing a matrix substrate having a main surface, a back surface opposed to the main surface, and a plurality of device-forming areas formed on the main surface; (b) mounting a plurality of semiconductor chips over the device-forming areas of the matrix substrate, respectively; (c) sealing the semiconductor chips with resin, and forming a resin body on the main surface of the matrix substrate; (d) attaching a surface of the resin body to an adhesive layer of a thermosetting tape; (e) after the step (d), cutting the matrix substrate into a plurality of semiconductor devices; (f) after the step (e), hardening the thermosetting tape by heating; and (g) after the step (f), picking up one of the semiconductor devices from the thermosetting tape, wherein the adhesive layer is comprised of a thermal curing type adhesive.
