Abstract:
1. A semiconductor chip package comprising: a first integrated semiconductor chip 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 nonconductive interposer substrate having opposite first and second surfaces, and having a through-hole extending therethrough from the first surface to the second surface; and a second integrated semiconductor chip 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 second integrated semiconductor chip being mounted on the first surface of the interposer substrate with the one side of the second integrated semiconductor chip facing the first surface of the interposer substrate, such that the second electrode is exposed through the through-hole, the second electrode to be wired through the through-hole to external terminals on the second surface of the interposer substrate, the first integrated semiconductor chip being mounted on the reverse side of the second integrated semiconductor chip with the reverse side of the first integrated semiconductor chip facing the reverse side of the second integrated semiconductor chip, wherein the through hole extending through the interposer substrate has a first width in a first direction and a second width in a second direction perpendicular to the first direction, and wherein the first width is smaller than both a width of the first semiconductor chip in the first direction and a width of the second semiconductor chip in the first direction.
