Abstract
PURPOSE:To reduce the areas of wiring channels and to improve the integration degree of cells in a standard cell system by a method wherein input/output terminals and a region where wiring is possible are provided in the interior of each cell. CONSTITUTION:Contact parts 40a, 41a, 42a, 43a, 44a-44c, 45a, 45b, 46a and 46b are input terminals of each cell to first layer metallic wirings and contact parts 40b, 41b, 42b, 43b, 44d, 45c and 46c are output terminals of each cell to the first layer metallic wirings. The first layer metallic wirings 58, 63, 77, 82 and 91, which pass through the interior of each cell, are extendedly provided in an X direction and are wired between the cells and second layer metallic wirings 50, 55, 57, 62, 67, 72, 74, 78, 79, 83-85 and 92 are extendedly provided in a Y direction and are wired between the cells. In such a way, wiring channels are not needed. Thereby, the integration degree of the cells is improved by a space equivalent to the wiring channels.
