Abstract
A technique relates to a method of optimizing self-aligned double patterning. Predefined locations for required metal cuts are provided in order to form metal wires from metal fills that have been cut. Extended locations for extended metal cuts are provided in order to cut adjacent metal fills. The adjacent metal fills are the metal fills that are adjacent to the predefined locations for the required metal cuts, and the extended metal cuts extend beyond the required metal cuts. The required metal cuts into the metal fills are performed and the extended metal cuts into the adjacent metal fills are performed.
