ABSTRACT:
A surge suppressor semiconductor structure includes a semiconductor substrate of a first conductivity type and an epitaxial semiconductor layer of a second conductivity type disposed thereon. A region in the epitaxial layer has a higher dopant concentration than the remainder of the epitaxial layer. This creates a junction at an interface of the substrate and the highly doped region of the epitaxial layer. A moat is disposed about the epitaxial layer and a portion of the substrate and dielectric material is disposed in the moat and on the epitaxial layer. Contacts are then formed to contact both the highly doped region of the epitaxial layer and the substrate.
