Patent ID: 8659127

Claim:
A semiconductor device comprising: a wiring substrate; and a semiconductor chip having a first face and a second face opposite to the first face, wherein the wiring substrate includes a glass plate whose thickness is equal to a thickness of the semiconductor chip, the glass plate having a first surface and a second surface opposite to the first surface, the glass plate having an opening portion penetrating through the glass plate between the first surface of the glass plate and the second surface of the glass plate, a resin portion having a first end face and a second end face opposite to the first end face, the resin portion penetrating through the glass plate between the first surface of the glass plate and the second surface of the glass plate, and a through wiring penetrating through the resin portion between the first surface of the glass plate and the second surface of the glass plate to electrically connect a first wiring layer formed on a side of the first surface of the glass plate with a second wiring layer formed on a side of the second surface of the glass plate, wherein the first surface of the glass plate, the first face of the semiconductor chip, and the first end face of the resin portion are aligned on a common plane, and the second surface of the glass plate, the second face of the semiconductor chip, and the second end face of the resin portion are aligned on another common plane, wherein the semiconductor chip is accommodated inside the opening portion, a space portion formed between an inner side surface of the opening portion and a side surface of the semiconductor chip is filled with the resin portion, and the resin portion is positioned inside the opening portion.
