Abstract
A Schottky diode and a method of manufacturing the Schottky diode are disclosed. The Schottky diode has an N-well or N-epitaxial layer with a first region, a second region substantially adjacent to an electron doped buried layer that has a donor electron concentration greater than that of the first region, and a third region substantially adjacent to the anode that has a donor electron concentration that is less than that of the first region. The second region may be doped with implanted phosphorus and the third region may be doped with implanted boron.
