Abstract
Input/output terminals 10 made of a first aluminium wiring layer are provided within cells 3a to 3c in the same cell row 30. A plurality of mains 7a to 7c made of a second aluminium wiring layer, which are electrically independent of the input/output terminals 10 of the standard cells 3a to 3c, a power source wire 1 and a grounding wire 2, are arranged between the input/output terminals 10 of the standard cells 3 to be connected so that they extend in parallel with a cell row extending direction. Via holes 8 are provided in regions in which the input/output terminals 10 overlap the mains 7 two-dimensionally to make electrical connection between the input/output terminals 10 and the mains 7. Since the wirings in the same cell row are executed within the cells in the cell row, an integration degree can be improved.
