RESIN-ENCAPSULATED SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

A first resin encapsulated body (25) and a second resin encapsulated body (26) are stacked to form a resin-encapsulated semiconductor device. The first resin encapsulated body (25) includes: a first semiconductor element (2); an external terminal (5); inner wiring (4); and a first resin (6) for covering those components, at least a rear surface of the external terminal (5), a rear surface of the semiconductor element (2), and a surface of the inner wiring (4) are exposed from the first resin (6). The second resin encapsulated body (26) includes: a second semiconductor element (7) having an electrode pad formed on a surface thereof; a second resin (8) for covering the second semiconductor element; and a metal body connected to the electrode pad, and is partly exposed from the second resin. The inner wiring and the metal body are electrically connected to each other.
