ABSTRACT:
Verification of the pattern area ratio of a semiconductor integrated circuit device or the pattern occupancy ratio in a check window set for the semiconductor integrated circuit device is performed on an assumption that a dummy pattern defined by process conditions is placed in an unoccupied region of the semiconductor integrated circuit device or in an unoccupied region in at least one instance provided in the semiconductor integrated circuit device.
