Classification: CPC H  B  C | IPC B  C  H

Claim 10:
11. A method for producing a semiconductor device, comprising, in the following order:
a step of attaching the temporary protective film for semiconductor sealing molding according to claim 1 on one surface of a lead frame having a die pad and an inner lead, in a direction in which an adhesive layer of the temporary protective film comes into contact with the lead frame, wherein the temporary protective film runs parallel to a shorter side in a case where the outer periphery of the lead frame is a rectangular shape, and parallel to any one side in a case where the outer periphery of the lead frame has a square shape;
a step of mounting a semiconductor element on a surface of the die pad, the surface being on the opposite side of the temporary protective film;
a step of providing a wire for connecting the semiconductor element and the inner lead;
a step of forming a sealing layer sealing the semiconductor element and the wire, and thereby obtaining a sealing molded body having the lead frame, the semiconductor element, and the sealing layer; and
a step of peeling off the temporary protective film from the sealing molded body.
