Patent ID: 7002251

Claim:
A semiconductor device comprising: a substrate including opposed first and second surfaces and a recess which is depressed in a direction from the first surface to the second surface, the first surface including the recess being covered with an insulating film; pads formed on the insulating film at a bottom surface of the recess; first external terminals formed on the insulating film on the first surface at an area surrounding the recess; wiring formed on the insulating film on the first surface for electrically connecting the pads to the first external terminals; a first semiconductor element including a third surface, on which second external terminals are formed, and a fourth surface opposed to the third surface, the first semiconductor element being accommodated in the recess and the second external terminals being electrically connected to the pads; a second semiconductor element including a fifth surface, on which third external terminals are formed, and a sixth surface opposed to the fifth surface, the second semiconductor element being accommodated in the recess and the sixth surface thereof being adhered to the fourth surface of the first semiconductor element.
