Abstract
An ESD protection structure includes a structure to be protected disposed in a semiconductor body. A region of a first conductivity type is disposed within the semiconductor body and a channel is disposed in the semiconductor body and extends through the region of the first conductivity type. A semiconductor of a second conductivity type is disposed within the channel adjacent the region of the first conductivity type such that the region of the first conductivity type and the semiconductor of the second conductivity type form a diode. At least one of the region of the first conductivity type and the semiconductor of the second conductivity type is electrically coupled to the structure to be protected.
