Claim Text:
1. A method, comprising: providing a non-transitory machine readable storage medium encoded with data representing a cell layout having patterns including a bus pattern, wherein the patterns of the cell layout are assigned into respective sets to be patterned using at least a first mask and a second mask for patterning a single layer of an IC; assigning a first portion of the bus pattern to be patterned by the first mask and a second portion of the bus pattern to be patterned by the second mask; assigning an overlap portion of the bus pattern to be patterned using the first mask and the second mask, including: outputting the cell layout to a machine readable storage medium to be read by a system for controlling a process to fabricate the first and second masks for patterning a semiconductor substrate using the first and second masks to pattern a single layer.
