Abstract

A basic cell is disclosed, which is small in area and has sufficient connection flexibility. for achieving a semiconductor integrated circuit with a higher density and a reduced manufacturing cost. In a basic cell, a terminal wire, which is connected to a transistor terminal with a contact, is placed in a first metal wiring layer, and a plurality of terminal wire connection points, which can be connected to a second metal wire through a first via, are provided on the terminal wire. Further, in a semiconductor integrated circuit, a circuit wire in a second metal wiring layer is placed along grid points with a fixed pitch, and is connected to a terminal connection point of a transistor terminal, which is displaced from the grid points, through a terminal wire provided in the first metal wiring layer.
