US Patent 11631672 Semiconductor integrated circuit

A semiconductor integrated circuit includes a substrate, and a standard cell on the substrate. The standard cell includes a first wiring structure electrically connecting a first gate pattern to a fourth gate pattern, and a second wiring structure electrically connecting a second gate pattern to a third gate pattern. The first wiring structure includes a first lower wiring layer, a second lower wiring layer, first and second intermediate wiring layers, and a first upper wiring layer. The second wiring structure includes a third lower wiring layer, a fourth lower wiring layer, third and fourth intermediate wiring layers, and a second upper wiring layer.
