Semiconductor device and a method of manufacturing the same

摘要

A semiconductor device according to the invention is provided with square first semiconductor chip and second semiconductor chip laminated with each one main surface opposite, a supporting lead a part of which is arranged between one main surface of the first semiconductor chip and one main surface of the second semiconductor chip and a resin sealing body that seals the first semiconductor chip, the second semiconductor chip and the supporting lead and is characterized in that the respective one main surfaces of the first semiconductor chip and the second semiconductor chip are bonded to a part of the supporting lead via an adhesive layer and a part of the supporting lead is formed so that it has smaller width than the respective sides of the first semiconductor chip and the second semiconductor chip.
