Abstract In a placement and routing for a standard cell type LSI design, each standard cell comprises a VDD power supply terminal formed of a P-type diffused layer, a VSS power supply terminal formed of an N-type diffused layer, and an input terminal and an output terminal formed of a first level metal. A plurality of standard cells are located to form a standard cell array, and VDD and VSS power supply lines formed of the first level metal are located to extend along opposite sides of the standard cell array, respectively. A power supply line formed of the diffused layer is extended from the power supply terminal to the power supply line of the first level metal, and a contact hole is formed at an overlapping portion between the power supply line of the first level metal and power supply line formed of the diffused layer.
