ABSTRACT:
In the disclosed method of manufacturing semiconductor devices with a single-sided resin-sealed package structure, when resin is filled into between the chip and the substrate, the occurrence of variations in the finishing dimensions of the package or defects in the outward appearance of the package is prevented. The disclosed manufacturing method comprises the step of using a guide plate for pouring resin and bringing one end of the guide plate into contact with one face end of a substrate or with a portion of one major surface near at least one side face of a chip in filling sealing resin between the chip and the substrate after the semiconductor chip has been mounted, with the face down, on one major surface of a wiring substrate having the wiring containing a connection section, the step of inclining the guide plate so that the guide plate may meet one major surface of the substrate at a specified angle, when or after one end of the guide plate is brought into contact with the substrate, and the step of supplying the resin to the opening between the chip and the substrate by supplying the resin onto the top surface of the guide plate and allowing the resin to flow over the top surface of the guide plate.
