ABSTRACT:
It is an object of this invention to make it possible to accurately simulate a manner in which carriers are transferred in a semiconductor device. A Fermi level setting means sets a Fermi level in a sink region of carriers, such as a vertical CCD portion of a CCD, and Boltzmann distribution equation solving means solve a Boltzmann distribution equation to obtain a carrier density in this Fermi level set region. In a CCD, the manner in which carriers are transferred from a photodiode portion to a vertical CCD portion in a CCD can be simulated accurately.
