  • Patent number: 9530689
    Abstract: Methods for fabricating integrated circuits are provided. One method includes decomposing a master pattern layout for a semiconductor device layer that includes a target metal line with a target interconnecting via/contact into a first sub-pattern and a second sub-pattern. The target metal line is decomposed into a first line feature pattern that is part of the first sub-pattern and a second line feature pattern that is part of the second sub-pattern such that the first and second line feature patterns have overlapping portions defining a stitch that corresponds to the target interconnecting via/contact. A first photomask is generated that corresponds to the first sub-pattern. A second photomask is generated that corresponds to the second sub-pattern.

  • Patent number: 9465907
    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.
