Abstract:
1. An electrostatic discharge (ESD) protection device comprising: a first diode comprising a first doped region of a first doping type, a first barrier region of a second doping type, an intrinsic or a substantially low doping of the first or the second doping type, a second barrier region of the first doping type, and a second doped region of the second doping type, wherein the first doped region is coupled to a node to be protected, and wherein the second doped region is coupled to a discharge node of the ESD protection device; and a second diode comprising a further first doped region of the first doping type, a further first barrier region of the second doping type, a further intrinsic or a substantially low doping of the first or the second doping type, a further second barrier region of the first doping type, and a further second doped region of the second doping type, wherein the further second doped region is coupled to the node to be protected, and wherein the further first doped region is coupled to the discharge node of the ESD protection device.
