Abstract:
1. A semiconductor device comprising: a semiconductor chip in which a plurality of semiconductor components are formed and a plurality of pads are arranged in a single line on a center part of a main surface of the semiconductor chip; a plurality of external connection contacts arranged in grids; and a plurality of wires for electrically connecting each of the pads and each of the external connection contacts; wherein the pads include a plurality of pad groups, each pad group including at least one power supply pad connected to the plurality of semiconductor components, at least one ground pad connected to the plurality of semiconductor components, and a plurality of signal pads respectively connected to the semiconductor components connected to the power supply pad and ground pad and for transmitting and receiving signals to/from the semiconductor components; wherein the power supply pad and the ground pad are commonly connected to at least two of the plurality of semiconductor components, wherein the power supply pad supplies a power supply voltage to the semiconductor components and the ground pad supplies a ground voltage to the semiconductor components; wherein in each of the pad groups, each of the signal pads is arranged immediately next to the power supply pad or the ground pad; wherein each of the wires extending from each of the signal pads is extended parallel to and in the same direction as a wire extending from the power supply pad or the ground pad which is immediately next to the signal pad in a same pad group; wherein the plurality of pad groups includes a first pad group wherein the wires extending from the signal pads of the first pad group extend in a first direction; and wherein the plurality of pad groups includes a second pad group immediately next to the first pad group, wherein the wires extending from the signal pads of the second pad group extend in a second direction opposite to the first direction.
