Abstract
Schottky barrier diodes, methods for fabricating Schottky barrier diodes, and design structures for a Schottky barrier diode. A guard ring for a Schottky barrier diode is formed with a selective epitaxial growth process. The guard ring for the Schottky barrier diode and an extrinsic base of a vertical bipolar junction diode on a different device region than the Schottky barrier diode may be concurrently formed using the same selective epitaxial growth process.
