An integrated circuit device such as a gate array or a master slice LSI device which is formed on a semiconductor chip and which comprises an inner cell array including a plurality of inner cells, an outer cell array including a plurality of outer cells formed around the inner cell array, a power supply portion having one or more outer power supply lines, and a plurality of inner power supply lines connected to the outer power supply lines and formed on the inner cell array. The ratio of the pitch length of the outer cells to the pitch length of the inner power supply lines or the inner cells is determined by the ratio of two integers. In the integrated circuit device, at least one set of an outer cell, and an inner cell which are arranged in a predetermined positional relation, is formed a plurality of times along a side of the semiconductor chip. |
