LADISPICE-1.2: a nonplanar-drift lateral DMOS transistor model and its application to power IC TCAD

A circuit simulation program (LADISPICE: LAteral Dmos transistor SPICE) has been developed for simulation and optimisation of power ICs which combine high-power lateral double-diffused MOS transistors with low-voltage logic and control elements on the same chip. This is a development of a previous static model and involves a charge-based dynamic model and a parasitic bipolar junction transistor model. These models have been incorporated into SPICE2G.6 source code and the paper demonstrates the excellent results. This new software represents an effective TCAD tool for the design and simulation of LDMOST power ICs
