Abstract :
This paper reports on a novel device, a high voltage NMOSFET with two different doping level drift regions. The device is compatible with 1.5 μm CMOS technology. The two different doped regions are formed with n well implantation and n field implantation in standard CMOS process. The experimental result shows that the die breakdown voltage of this NMOSFET is from 120 V to 290 V according to different structures, such as drift length and drift doping level
