    摘要: The preferred embodiment of the present invention overcomes the limitations of the prior art and provides a device and method to decrease the latch-up susceptibility of an ESD structure by suppressing the injection of minority carriers that cause transistor action to occur. This is accomplished, for example, by using a metal contact to the n-substrate or n-well in place of or in parallel with the prior art p-diffusion. Using such a metal contact forms a Schottky Barrier Diode (SBD) with the ESD structure. Since the SBD is a majority-carrier device, negligible minority carriers are injected when the SBD is in forward bias, thereby reducing the likelihood of latch-up.

    摘要: A &Dgr;Z calculator calculates difference between an inversion layer capacitance by a classical theory and an inversion layer capacitance by a quantum theory, calculates &Dgr;Z which is a thickness of a semiconductor substrate equivalent to the difference in inversion layer capacitance. A discretization mesh generator generates a Delaunay discretization mesh for a structure of the semiconductor device to be evaluated. An electrical parameter calculator calculates 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 the stored &Dgr;Z from the interface between the insulating film and the semiconductor substrate.
