US 7747976 B2 A semiconductor cell and a semiconductor circuit
utilizing semiconductor cells. The semiconductor cell includes a
rectangular boundary and a power layout, where the power layout
does not contact any pair of opposite sides of the rectangular
boundary. Additionally, the semiconductor circuit includes a
plurality of semiconductor cells. Each semiconductor cell
includes a rectangular boundary and a power layout, where the
power layout does not contact any pair of opposite sides of the
rectangular boundary. Because conventional power strips are
avoided, the present invention can reduce height of each
semiconductor cell, and therefore increase integration of the
semiconductor circuit (i.e., the integrated circuit). 1. A
semiconductor circuit, comprising: a plurality of semiconductor
cells, wherein each semiconductor cell comprises a power layout,
the power layout of the semiconductor cell does not traverse
along at least one side of the semiconductor cell; and a routing
layout for routing wirings on a
