Abstract

A semiconductor cell structure includes four transistors, two gate-strips, four pairs of conductive segments, and a plurality of horizontal routing lines. Each of the two gate-strips intersects a first-type active zone and a second-type active zone. A first conductive segment is configured to have a first supply voltage. A second conductive segment is configured to have a second supply voltage. The first gate-strip is conductively connected to the second conductive segment. Each of the horizontal routing lines intersects one or more conductive segments over one or more corresponding intersections while conductively isolated from the one or more conductive segments at each of the one or more corresponding intersections.

Description

technical field [0001] The present disclosure relates to a design layout of a semiconductor structure. Background technique [0002] The recent trend to miniaturize integrated circuits (ICs) has resulted in smaller components that consume less power but provide more functionality at higher speeds. The miniaturization process also leads to tighter constraints on integrated circuit layout design. During layout design of an integrated circuit, functional or physical units are often placed in a circuit layout and routed to form a functional circuit. In addition to the normal connection cells used to form functional circuits, the layout design of integrated circuits often includes engineering change order (ECO) cells distributed in the floor plan. According to the original circuit design of the integrated circuit, the engineering change order unit is not functionally connected with the normal working electronic parts. When an ECO unit is connected to a functioning electronic c...
