Taiwan Semiconductor Manufacturing has been granted a patent for a method of generating a layout diagram for wire routing in a multi-patterning context. The method involves placing a cut pattern over a conductive pattern, determining if it violates a design rule, and temporarily preventing placement until a correction is made. The patent aims to improve the efficiency and accuracy of wire routing arrangements.

Method for generating layout diagram of wire routing arrangement
A recently granted patent (Publication Number: US11775727B2) describes a method for generating a layout diagram of a wire routing arrangement in a multi-patterning context with multiple masks. The method involves placing a given cut pattern at a candidate location over a corresponding portion of a conductive pattern in a metallization layer. The method then determines whether the candidate location violates a design rule by resulting in a non-circular group or a cyclic group. If a violation is detected, the placement of the cut pattern is temporarily prevented until a correction is made to avoid violating the design rule.
The method includes various scenarios for making corrections to
