Claim:
1. A device comprising: a semiconductor substrate; an n-type well region in the semiconductor substrate; a P-type Field Effect Transistor (PFET) comprising: a first Schottky diode comprising: a second Schottky diode comprising: a heavily doped p-type region; a first metal-containing plate over and contacting a first portion of the n-type well region, and over and connected to the first source/drain region, wherein: a second metal-containing plate over and contacting a second portion of the n-type well region, and over and connected to the second source/drain region, wherein the second metal-containing plate is the second anode of the second Schottky diode, and the n-type well region continuously extends from the first metal-containing plate to the second metal-containing plate.
