Abstract
In a power line structure for supplying power to standard cells, buried power lines extending in the X direction are placed at a given spacing in the Y direction. A local power line extending in the Y direction is connected with the buried power lines. Metal power lines extending in the X direction are formed in an upper-layer metal interconnect layer and connected with the local power line. The spacing of placement of the metal power lines in the Y direction is greater than the spacing of placement of the buried power lines.
