Abstract: Pattern densities of an original designed layout of a workpiece, such as a wafer, are examined. According to the examined results, the original layout is then divided into at least a first region and a second region, a pattern density of the first region being different from a pattern density of the second region. By using an optical proximity correction (OPC) models to correct and modify the first region and the second region, a predetermined modified layout is formed on a photomask. The modified layout can be transfer to a wafer by a photolithography process so that the wafer produces a pattern the same as a pattern of the original layout.
