0.18μm BCD technology with the best-in-class nLDMOS is presented. The drift of nLDMOS is optimized to ensure lowest Rsp by using multi-implants and appropriate thermal recipe. The optimized 24V nLDMOS has BVDSS=36V and Rsp=14.5 mΩ-mm2. Electrical SOA and long-term hot electron (HE) SOA are also evaluated. The maximum operating voltage less than 10% degradation of on-resistance is 24.4V.
