Abstract
A semiconductor device designing method includes calculating capacitance. The semiconductor device has a semiconductor substrate, an insulator formed on the semiconductor substrate, and an electrode formed on the insulator. The capacitance is calculated under an approximation assuming a portion of the semiconductor substrate, the insulator and a portion of the electrode to be one of a conductor and a dielectric depending on electric characteristics thereof, respectively.
