Semiconductor integrated circuit having a gate array structure

摘要

In a semiconductor integrated circuit having a gate array structure, within a cell, isolation transistors are disposed in series between an intra-cell gate output terminal and an intra-cell power supply wiring section, or between the intra-cell gate output terminal and an intra-cell ground wiring section. Isolation transistors are disposed in series between an extra-cell gate output terminal and an extra-cell power supply wiring section between cells, or between the extra-cell gate output terminal and an extra-cell ground wiring section.
