Abstract
In a semiconductor device characteristic simulation apparatus and its method, performance characteristics of a semiconductor integrated circuit are image-displayed as a distribution on a semiconductor substrate without actually fabricating the semiconductor integrated circuit. To simulate the fluctuation in device characteristic values of a plurality of semiconductor integrated circuits formed on a semiconductor substrate by applying various types of processing to the semiconductor substrate, the present invention generates simulation data for executing simulations in accordance with measured data for a plurality of predetermined portions on the semiconductor substrate after processed, calculates device characteristic values of the semiconductor integrated circuits in accordance with the simulation data, and displays the fluctuation of device characteristic values as a distribution on the semiconductor substrate.
