PURPOSE:To facilitate a layout change by forming a block with a domain having such pattern as is optimal to constitute an FF circuit and with a domain having such patern as is optimal to constitute a logical gate around said domain. CONSTITUTION:A single unit of gate circuit is provided in plural to each upper and lower domain of an FF circuit, and one block is obtained through providing a wiring channel 14 with which to wire the gate circuit on both upper and lower parts and a ground wiring part 15 beneath the lower wiring channel 14. An I<2>L semiconductor domain is formed by arranging the block in plural vertically and horizontally. |
