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

摘要

A circuit simulation program (LADISPICE: LAteral Dmos transistornSPICE) has been developed for simulation and optimisation of power ICsnwhich combine high-power lateral double-diffused MOS transistors withnlow-voltage logic and control elements on the same chip. This is andevelopment of a previous static model and involves a charge-basedndynamic model and a parasitic bipolar junction transistor model. Thesenmodels have been incorporated into SPICE2G.6 source code and the paperndemonstrates the excellent results. This new software represents anneffective TCAD tool for the design and simulation of LDMOST power ICs
