摘要
本文提出了一种新型的内置FR/JTE横向DMOS结构,并对其进行了耐压分析,结果表明,该结构具有与RESURF器件相媲美的击穿电压,并且工艺简单,受工艺参数波动的影响较小,相对于内场限环结构,其耐压高且导通电阻低。
A new structure of LDMOST with internal FR/JTE termination is set forth, and the parameters of the FR/JTE are optimized. It is shown that under optimal condition, the breakdown voltage of the new device is higher than that of the device using two internal FLRs, and is approach to that of RESURF devices, and the on\|resistance of the new device is smaller than that of the device using two internal FLRs.
