Patent ID: 8704376

Claim:
A layout structure comprising: a substrate; a well in the substrate; a first dopant area in the well; a first contact element in electrical connection with the first dopant area; a first conductive element on a level of a first conductive layer and in electrical connection with the first contact element; a first via in electrical connection with the first conductive element on the level of the first conductive layer; a first conductive element on a level of a second conductive layer and in electrical connection with the first via; a second dopant area in the well; a second contact element in electrical connection with the second dopant area; a second conductive element on the level of the first conductive layer and in electrical connection with the second contact element; a second via in electrical connection with the second conductive element on the level of the first conductive layer; and a second conductive element on the level of the second conductive layer and in electrical connection with the second via, wherein the first conductive element on the level of the second conductive layer is configured to be electrically coupled with a first power supply source; and the second conductive element on the level of the second conductive layer is configured to be electrically coupled with a second power supply source different from the first power supply source.
