    摘要: Some aspects of the present disclosure provide for a method of automatically balancing mask misalignment for multiple patterning layers to minimize the consequences of mask misalignment. In some embodiments, the method defines a routing grid for one or more double patterning layers within an IC layout. The routing grid has a plurality of vertical grid lines extending along a first direction and a plurality of horizontal grid lines extending along a second, orthogonal direction. Alternating lines of the routing grid in a given direction (e.g., the horizontal and vertical direction) are assigned different colors. Shapes on the double patterning layers are then routed along the routing grid in a manner that alternates between different colored grid lines. By routing in such a manner, variations in capacitive coupling caused by mask misalignment are reduced.
