Patent attributes
A semiconductor integrated circuit device of improved wireability, fewer number of wiring layers and strengthened power supply includes a plurality of power pads placed on a semiconductor chip and a plurality of signal pads placed on the semiconductor chip and configured to have a width less than that of the power pads. The signal pads and the power pads are placed in the uppermost wiring layer among a plurality of wiring layers. Signal wiring connecting I/O cells and signal pads is disposed in the uppermost wiring layer. First power wiring electrically connecting the I/O cells and first power pads is disposed in the uppermost wiring layer. Second power wiring connecting internal circuits and second power pads is disposed in the uppermost wiring layer.
