Summary:

High-voltage devices are utilized for a variety of applications, with application voltages ranging from a few volts to a few hundred volts. To develop efficient circuits for the variety of applications, accurate modeling of the basic device is the key. Here our purpose is to develop a compact model for the DMOS structure which considers the vertical 2D current flow and to implement it into HiSIM_HV. The accuracy of the developed model is verified.
