Abstract :
The dependence of device structures and layout parameters on ESD robustness of HV MOSFETs in high-voltage 40-V CMOS process has been investigated by device simulation and verified in silicon test chips. It was demonstrated that a new ESD protection structure with p-type SCR embedded into the HV PMOS has the highest ESD robustness in a given 40-V CMOS process.
