摘要：Improved Schottky diodes with reduced leakage current and improvedbreakdown voltage are provided by building a JFET with its current path of a firstconductivity type serially located between a first terminal comprising a Schottky contactand a second terminal. The current path lies (i) between multiple substantially parallel
finger regions of a second, opposite, conductivity type substantially laterally outboard ofthe Schottky contact, and (ii) partly above a buried region of the second conductivity typethat underlies a portion of the current path, which regions are electrically coupled to thefirst terminal and the Schottky contact and which portion is electrically coupled to thesecond terminal. When reverse bias is applied to the first terminal and Schottky contact,the current path is substantially pinched off in vertical or horizontal directions or both,thereby reducing the leakage current and improving the breakdown voltage of thedevice.
