Abstract
In this work, layout skills using three dimensional (3D) fish bone, slot, and island patterns to enhance the breakdown voltage of PW/NW junction of lateral MOSFETs is developed. Novel lateral double diffused MOSFETs (LDMOSFET) and Double Diffused Drain MOSFETs (DDDMOSFET) without any high voltage (HV) layer are achieved in a standard 5V low voltage (LV) CMOS technology. From the experiment results, the developed DDDMOSFETs and LDMOSFETs can be used for 10V and 60V application respectively. © 2013 IEEE.
