Abstract:
1. A manufacturing method of a semiconductor device, comprising the steps of: (a) providing a plate member having a main surface and a back surface opposing to the main surface, a semiconductor chip having a front surface, an electrode formed on the front surface, and a rear surface opposing to the front surface being mounted on the main surface of the plate member such that the rear surface faces to the main surface, and a wire electrically connecting the electrode with the main surface of the plate member; (b) providing a resin-molding metal mold including a first molding die having a first surface, a first cavity formed in the first surface, a first projecting portion formed in the first cavity, a first hole reaching to a first projecting portion surface of the first projecting portion, a first pin arranged inside of the first hole, and a second molding die having a second surface opposing to the first surface, the first pin having an end face closest to the second surface, the end face of the first pin being located in the first hole retracted from the first projecting portion surface; (c) disposing the plate member between the first molding die and the second molding die such that the semiconductor chip is located inside of the first cavity, and such that the front surface of the semiconductor chip faces to the first cavity; (d) after the step (c), injecting resin having a filler therein into the first cavity in such a state that the end face of the first pin is retracted from the first projecting portion surface, and forming a molded body sealing the semiconductor chip by curing the resin, wherein in injecting the resin having a filler therein and forming the molded body by curing the resin, in step (d), the end face of the first pin remains retracted from the first projecting portion surface; and (e) after the step (d), separating the molded body from a surface in the first cavity, and removing the plate member on which the molded body is formed from between the first molding die and the second molding die; wherein in the step (e), the molded body is separated from the surface in the first cavity by pressing the end face of the first pin to a surface of the molded body; and wherein in the step (c), the plate member on which the semiconductor chip is mounted is disposed between the first molding die and the second molding die such that the wire does not contact with the first projecting portion.
