Abstract

A method of manufacturing a resin-encapsulated semiconductor device, which includes the steps of, mounting a semiconductor element facedown on a substrate provided with a wiring circuit with a main surface of the semiconductor element being faced to the substrate, positioning the substrate bearing the semiconductor element in a mold together with a sealing resin, and applying a pressure onto the sealing resin to move the sealing resin to a space between the semiconductor element and the substrate, to the sides of the semiconductor element and to the bottom surface of the semiconductor element, thereby sealing the semiconductor element with the sealing resin.
