Patent ID: 8264011

Claim:
A semiconductor device having a plurality of aligned standard cells, comprising: a first power supply portion and a second power supply portion included by the plurality of aligned standard cells in common, wherein a first standard cell as one of said aligned standard cells is a function element, wherein the first standard cell includes a first transistor and a signal line, wherein the first power supply portion formed in the first standard cell includes a first power supply line and a second power supply line, wherein the first power supply line extends along a first boundary of the aligned standard cells which are adjacent to each other and is arranged on the first boundary, wherein the second power supply portion extends along a second boundary of the aligned standard cells which are adjacent to each other and is arranged on the second boundary, wherein the second power supply line is electrically connected to a portion of the first power supply line and is electrically connected to a source terminal of the first transistor, wherein a first power supply voltage is supplied to the first power supply portion, and a second power supply voltage which is higher than the first power supply voltage is supplied to the second power supply portion, and wherein a portion of the signal line that extends along a same direction as the first boundary is entirely between an edge of the first power supply line and an edge of the second power supply line, and the first power supply line covers at least a part of the signal line and at least a part of the second power supply line, as viewed from a plane.
