ABSTRACT:
A semiconductor integrated circuit of standard-cell type or gate-array type includes a plurality of first cells arranged in a plurality of parallel lines, the first cells having first wirings for supplying power, the first wirings being extended over a plurality of the first cells arranged in the same line in a direction of the same line of the first cells, a second cell disposed in the neighbourhood of some of the first cells and having a dimension larger than the first cells, said second cell having second wirings on a periphery thereof to surround circuit portion of the second cell and means for connecting the second wirings with the first wirings in the first cells in the neighbourhood of the second cell.
