  • Patent number: 9390223
    Abstract: A method of determining whether a layout is colorable includes assigning nodes to polygon features of the layout. The method includes designating nodes as being adjacent nodes for nodes separated by less than a minimum pitch. The method includes iteratively removing nodes having less than three adjacent nodes from consideration to identify a node arrangement, wherein all nodes in the node arrangement have at least three adjacent nodes. The method includes determining whether the layout is colorable based on the node arrangement. Determining whether the layout is colorable includes independently assessing each internal node of node arrangement to determine whether each internal node of the node arrangement is colorable. The method includes generating a colored layout design for fabrication of the semiconductor device if each internal node of the node arrangement is colorable; and modifying the layout if at least one internal node of the node arrangement is not colorable.
