Abstract:
1. A semiconductor device comprising: a semiconductor chip having a trench opening toward a surface side and a side surface side on a periphery of a surface thereof; a sealing resin layer stacked on this semiconductor chip to enter the trench for sealing the surface side of the semiconductor chip; a plurality of posts penetrating the sealing resin layer in a stacking direction of the semiconductor chip and the sealing resin layer, each having a base end electrically connected with an uppermost wiring layer; and external connecting terminals formed in contact with respective tip ends of the posts and protruding from the sealing resin layer, wherein the semiconductor chip comprises a semiconductor substrate serving as a base of the semiconductor chip, a plurality of wiring layers vertically stacked on this semiconductor substrate, an interlayer film interposed between the wiring layers, and a passivation film covering a surface of an uppermost wiring layer, and a portion of the sealing resin layer entering the trench covers side surfaces of the interlayer film and the passivation film.
