ABSTRACT:
A method for providing a programmable electrostatic discharge (ESD) protection device is provided. The method includes providing a source diffusion in a substrate, providing a deeper body diffusion in the substrate, providing a gate at a space between the source diffusion and the body diffusion, and providing a variable structure for shorting the source diffusion and the body diffusion to each other when ESD voltage is encountered on a circuit connected thereto, wherein the variable structure comprises a plurality of contacts over the source diffusion for the source diffusion to be grounded to the body diffusion.
