Patent ID: 8134219

Claim:
A Schottky diode having first and second terminals, comprising: a semiconductor (SC) substrate having a first region of a first conductivity type and first doping concentration proximate a first surface of the substrate; a Schottky electrode contact on the first surface of the first region forming a Schottky junction therebetween, wherein the Schottky electrode contact is ohmically coupled to the first terminal; a second region of the first conductivity type and second doping, contacting the first region, laterally separated from the Schottky electrode contact and ohmically coupled to the second terminal; multiple finger regions of a second, opposite, conductivity type and third doping ohmically coupled to the first terminal and extending from the first region into the second region, wherein first portions of the second region lies between the multiple finger regions; and a further region of the second conductivity type and fourth doping, located in the second region spaced apart from the first surface by the first portions of the second region and ohmically coupled to the first terminal, wherein the further region, the multiple finger regions and the second region form a junction field effect transistor (JFET), with the further region and the multiple substantially parallel finger regions adapted to act as gates of the JFET and the second region adapted to contain a channel of the JFET.
