ABSTRACT:
A layout structure of a semiconductor integrated circuit is provided with which narrowing and breaking of metal interconnects near a cell boundary can be prevented without increasing the data amount and processing time for OPC. A cell A and a cell B are adjacent to each other along a cell boundary. The interconnect regions of metal interconnects from which to the cell boundary no other interconnect region exists are placed to be substantially axisymmetric with respect to the cell boundary, while sides of diffusion regions facing the cell boundary are asymmetric with respect to the cell boundary.
