  • Method and apparatus for achieving multiple patterning technology compliant design layout
    Patent number: 8418111
    Abstract: A method and apparatus for achieving multiple patterning compliant technology design layouts is provided. An exemplary method includes providing a routing grid having routing tracks; designating each of the routing tracks one of at least two colors; applying a pattern layout having a plurality of features to the routing grid, wherein each of the plurality of features corresponds with at least one routing track; and applying a feature splitting constraint to determine whether the pattern layout is a multiple patterning compliant layout. If the pattern layout is not a multiple patterning compliant layout, the pattern layout may be modified until a multiple patterning compliant layout is achieved.
