Patent ID: 7075177

Claim:
A semiconductor chip package comprising: a first integrated semiconductor chip having a first chip size, having a one side and a reverse side, and having a first electrode for wiring on the one side of the first integrated semiconductor chip; a second integrated semiconductor chip having a second chip size, having a one side and a reverse side, and having a second electrode for wiring on the one side of the second integrated semiconductor chip, the first integratd semiconductor chip being mounted to the second integrated semiconductor chip with the reverse side of the second integrated semiconductor chip facing the reverse side of the first integrated semiconductor chip; a nonconductive interposer substrate having opposite first and second surfaces, and having a through-hole extending therethrough from the first surface to the second surface, the through-hole being larger than the second chip size; an adhesive sheet having opposite first and second surfaces, the adhesive sheet being formed of a sheet-shaped adhesive material provided on the interposer substrate at the first surface of the interposer substrate so as to cover the through-hole, the second surface of the adhesive sheet being exposed through the through-hole, the second surface of the adhesive sheet being exposed thorugh the though-hole, the side of the interposer substrate at the second surface of the interposer substrate, wherein the reverse side of the second integrated semiconductor chip is fixed to the second surface of the adhesive sheet, and the reverse side of the first integrated semiconductor chip is fixed to the first surface of the adhesive sheet so as to face the reverse side of the second integrated semiconductor chip at a position at which the second integrated semiconductor chip is fixed, whereby the second electrode can be wired to external terminals on the second surface of the interposer substrate.
