SEMICONDUCTOR DEVICE AND ITS MANUFACTURE, AND SEMICONDUCTOR DEVICE PACKAGING STRUCTURE

摘要

A semiconductor device comprising a semiconductor chip, a wiring substrate provided surrounding the semiconductor chip, leads projected from the wiring substrate and connected to the semiconductor chip, a stiffening member provided on one main surface of the wiring substrate, surrounding-the semiconductor chip, a plurality of bumps provided along a periphery of the wiring substrate on another main surface of the wiring substrate opposite to the main surface where the stiffening member is provided, and resin covering the semiconductor chip and the leads. The leads connected to the semiconductor chip are bend-processed toward a side where the stiffening member of the wiring substrate is provided or a side where the plurality of bumps are formed. The leads and the semiconductor chip are connected such that the surface of the semiconductor chip opposite to the surface connected to the leads is positioned on a side opposite to the side where the leads are bend-processed.
