    摘要: Among other things, one or more techniques for graded dummy insertion and a resulting array are provided herein. For example an array is a metal oxide semiconductor (MOS) array, a metal oxide metal (MOM) array, or a resistor array. In some embodiments, a first region and a second region are identified based on a density gradient between a first pattern density associated with the first region and a second pattern density associated with the second region. For example, the first pattern density and the second pattern density are gate densities and/or poly densities. To this end, a dummy region is inserted between the first region and the second region, the dummy region includes a graded pattern density based on a first adjacent pattern density and a second adjacent pattern density. In this manner, graded dummy insertion is provided, thus enhancing edge cell performance for an array, for example.
