Abstract

Abstract PURPOSE:To shorten wiring lengths by arranging both P-type semiconductor cells and N-type semiconductor cells so that each type of cell relatively neighbors in both row and column directions. CONSTITUTION:P-type semiconductor cells and N-type semiconductor cells are so arranged that each type of cell relatively neighbors in both row and column directions, or a pattern of P, N, P, N... in the row direction and a pattern of N, P, N, P... appear. According to the constitution, it is possible to make connections between the P-type semiconductor cell and the N-type semiconductor cell in both row and column directions, thereby allowing formation of a flip-flop, etc., in either direction, lengthwise or widthwise. Hence, when forming a flip-flop, etc., wiring lengths can be shortened, whereby a delay time can be reduced.
