摘要
The hot-carrier-induced on-resistance degradations of step gate oxide NLDMOS (SG-NLDMOS) transistors are investigated in detail by a DC voltage stress experiment, a TCAD simulation and a charge pumping test. For different stress conditions, degradation behaviors of SG-NLDMOS transistors are analyzed and degradation mechanisms are presented. Then the effect of various doses of n-type drain drift (NDD) region implant on R-on degradation is investigated. Experimental results show that a lower NDD dosage can reduce the hot-carrier induced Ron degradation effectively, which is different from uniform gate oxide NLDMOS (UG-NLDMOS) transistors.
