Semiconductor structure

Abstract

A semiconductor structure includes a first spare cell region, a first conductive line and a second conductive line. The first spare cell region has a plurality of spare cells. The first conductive line is coupled between a first reference voltage and the plurality of spare cells, and is arranged for providing the first reference voltage to the plurality of spare cells of the first spare cell region. The second conductive line is coupled to a plurality of spare cells, and is arranged for providing a second reference voltage to the plurality of spare cells of the first spare cell region.

Description

【Technical field】 [0001] The present invention relates generally to semiconductor structures, and more particularly, to semiconductor structures having spare cell regions for reducing leakage power. 【Background technique】 [0002] A standard integrated circuit (Integrated Circuit, IC) includes a large number of electronic components, units, and circuit modules for implementing certain functions required by design specifications. These components, units, and circuit modules are generally constructed on a semiconductor substrate with overlapping metal layers, where conductive patterns ( ) are deployed as an interconnection network. Like properly functioning electronic components, ICs also have redundant or dummy cells that do not play an active role in the operation of the IC. Although spare cells may be designed to perform certain functions, according to the original circuit design of the IC, they are not connected to the normal operation of the electronic components, but ca...
