PROBLEM TO BE SOLVED: To prevent arrangement with excessive substrate contacts to reduce the chip area and suppress the cost. SOLUTION: Related to a standard cell arrangement process P, based on the information provided by a cell arranged in an array in a standard cell arrangement region, and the width of array in the standard cell arrangement region as well as the data for the interval with which at least one substrate contact must be arranged, the number of substrate contacts added to the array in the standard cell arrangement region is acquired. A region where a substrate contact can be added is assured for arrangement of a cell, and cell's movement and arrangement with the substrate contact are performed so that at least one substrate contact is present in an interval L.
