Semiconductor device

Abstract

Abstract PURPOSE:To effectively utilize a layout design by a computer by forming a power source connecting pad region at the corner of the periphery formed with an externally connecting pad region, thereby improving the periodic property of the pattern. CONSTITUTION:A semiconductor device 1 has a basic cell array forming region at the center. A power source pad regions GND, VCC are formed at the corner of the periphery. Input/output buffer regions 4'-1-4'-4' pad regions P'57-P'60, other input/output buffer regions 3-1-3-56 and their pad resions P1-P56 are formed at the periphery except the corners with periodic property. As a result, the layout design by a computer can be effectively utilized, thereby improving the reliability.
