Abstract
One illustrative method disclosed herein involves producing an initial circuit layout, prior to decomposing the initial circuit layout, identifying at least one potential non-double-patterning-compliant (NDPC) pattern in the initial circuit layout, fixing the at least one potential non-double-patterning-compliant (NDPC) pattern so as to produce a double-patterning-compliant (DPT) pattern, producing a modified circuit layout by removing the potential non-double-patterning-compliant (NDPC) pattern and adding the double-patterning-compliant (DPT) pattern to the initial circuit layout, and performing design rule checking and double patterning compliance checking on the modified circuit layout.
