DUMMY GATE CELL, CELL BASE IC, AND LAYOUT SYSTEM AND LAYOUT METHOD OF CELL BASE IC

摘要

PROBLEM TO BE SOLVED: To provide a dummy gate cell, a cell base IC, and a layout system and a layout method of the cell base IC in which antenna effects can be suppressed while reducing loss in a wiring property and an area.SOLUTION: Drain electrodes 10, 11 of an nMOS transistor 150 and a pMOS transistor 151 which comprise a CMOS inverter are made to be non-connected, and they are arranged in an unused area 150 which is not occupied by a basic cell 103 in a cell base IC 101.
