Abstract:
A system for evaluating electrical parameters of a semiconductor device, comprising:a .DELTA.Z calculator for calculating difference between an inversion layer capacitance by a classical theory and an inversion layer capacitance by a quantum theory, calculating .DELTA.Z which is a thickness of a semiconductor substrate equivalent to the difference in inversion layer capacitance, and storing the .DELTA.Z;a discretization mesh generator for generating a Delaunay discretization mesh for a structure of the semiconductor device to be evaluated, and storing the discretization mesh; andan electrical parameter calculator for calculating electrical parameters of the semiconductor device under constraint that a charge density of channel conductivity type of the semiconductor device is set to zero at discretization mesh points of the discretization mesh on an interface between an insulating film and the semiconductor substrate and at discretization mesh points of the discretization mesh in the semiconductor substrate which are located within a distance less than or equal to the stored .DELTA.Z from the interface between the insulating film and the semiconductor substrate.
