Abstract
A method for processing design pattern data of a semiconductor integrated circuit includes determining whether or not there are lower-level cells whose individual size is equal to or below a threshold, and if there are such lower-level cells whose individual size is equal to or below the threshold, collecting the lower-level cells to define a higher-level cell whose size is greater than the threshold and replacing the lower-level cells with the higher-level cell.
