    Abstract: An extraction unit extracts a metal pattern constituting a semiconductor integrated circuit from layout data. A setting unit sets up a region including the metal pattern extracted by the extraction unit. An evaluation unit calculates the metal coverage rate of the region and to evaluate whether the metal coverage rate is equal to or more than a predetermined value. An insertion unit inserts a dummy metal pattern into the region when the metal coverage rate is evaluated as a value smaller than the predetermined value by the evaluation unit.
