Abstract: An ESD protection device includes a PN diode formed in a semiconductor body. The PN diode has a first contact coupled to a metal structure on a front side of the semiconductor body and a second contact coupled to a metal structure on a back side of the semiconductor body. The metal coupled to the first contact is spaced apart from the metal coupled to the second contact by a thickness of the semiconductor body. This spacing greatly reduces the capacitance associated with the metal structures, which can substantially reduce the overall capacitance added to an I/O channel by the ESD protection device and thereby improve the performance of a high-speed circuit that uses the I/O channel.
