Classification: CPC C  B  H | IPC C  H

Claim 6:
7. A method of producing a semiconductor package, comprising:
a first step of providing an adhesive layer by thermocompression bonding the film-like adhesive according to claim 5 to a back surface of a semiconductor wafer in which at least one semiconductor circuit is formed on a surface, and providing a dicing tape via the adhesive layer;
a second step of dicing the semiconductor wafer and the adhesive layer simultaneously to obtain a semiconductor chip with an adhesive layer, the semiconductor chip with an adhesive layer including the semiconductor wafer and the adhesive layer on the dicing tape;
a third step of removing the dicing tape from the adhesive layer and thermocompression bonding the semiconductor chip with an adhesive layer and a wiring board via the adhesive layer; and
a fourth step of thermally curing the adhesive layer.
