  • Patent number: 10770304
    Abstract: A method of fabricating an integrated circuit (IC) uses a first lithography technique having a first resolution and a second lithography technique having a second resolution lower than the first resolution. The method includes deriving a graph from an IC layout, the graph having vertices and edges that connect some of the vertices, the vertices representing IC patterns in the IC layout, the edges representing spacing between the IC patterns that are smaller than the second resolution. The method further includes classifying the edges into at least two types, a first type of edges representing spacing that is smaller than the first resolution, a second type of edges representing spacing that is equal to or greater than the first resolution but smaller than the second resolution.
