Abstract
A design method of a semiconductor device includes setting an inspection region of layout data generated based on circuit data, calculating an area ratio of a first area to a second area, the first area indicating an area of the inspection region, the second area indicating a sum of a surface area of a plane that a first member contacts with a second member, the second member contacting with the first member constituting a circuit element included in the inspection region, the second member further having different heat reflective properties from the first member, and arranging a dummy element in the layout data so that the area ratio is within a predetermined range in each inspection region of the layout data.
