ABSTRACT:
An electrostatic discharge (ESD) protection device is disclosed. The ESD protection device comprises a source diffusion in a substrate and a deeper body diffusion in the substrate. The ESD protection device further includes a gate function provided at a space between the source diffusion and the body diffusion surface terminations; and further includes a drain located a predetermined distance from the body diffusion. Finally, the ESD protection device includes a structure for shorting the source and the body diffusion to each other and to ground at variable distances from the channel region, thus providing a programmable variable snap back voltage to provide a protection when an ESD voltage is encountered.
