Abstract:
1. A semiconductor device comprising: a wiring board; a first semiconductor chip that is mounted over a first surface of the wiring board and is rectangular in plan; and a second semiconductor chip disposed over the first semiconductor chip, wherein the first semiconductor chip has an element formation surface facing the first surface and has a plurality of first through-silicon vias, wherein the second semiconductor chip is electrically coupled to the first through-silicon vias of the first semiconductor chip, wherein, where a direction in parallel with a long side of the first semiconductor chip is defined as a row direction and a direction perpendicular to the long side of the first semiconductor chip is defined as a column direction, each one of the first through-silicon vias is arranged on any one of grid points arranged in m rows and n columns (m>n), and wherein, as viewed in a cross section taken along a short side of the first semiconductor chip, the center of a through-silicon via area, which is defined by coupling the outermost grid points arranged in m rows and n columns, is off center of the short side of the first semiconductor chip in a first direction.
