    Abstract: A method includes electrically connecting a plurality of cells of a standard cell library to a power rail. A contact area is deposited to connect a first active area and a second active area of a cell of a plurality cells. The first area and the second area are located on opposite sides of the rail and electrically connected to different drains. The contact area is electrically connected to the power rail using a via. The contact area is masked to remove a portion of the contact area to electrically separate the first active are from the second active area.

    Abstract: One illustrative method disclosed herein involves, among other things, decomposing an initial circuit layout into first and second mask patterns, for the first mask pattern, identifying a first four-polygon pattern in the first mask pattern that violates a multi-polygon constraint rule, wherein the first four-polygon pattern comprises four polygons positioned side-by-side in the first mask pattern, and recoloring one or two of the polygons in the first four-polygon pattern in the first mask pattern to the second mask pattern to eliminate the first four-polygon pattern from the first mask pattern without introducing any design rule violations in the initial circuit layout.
