JUNCTION BARRIER SCHOTTKY DIODES WITH CURRENT SURGE CAPABILITY |
摘要 |
An electronic device includes a silicon carbide drift region having a first conductivity type, a Schottky contact on the drift region, and a plurality of junction barrier Schottky (JBS) regions at a surface of the drift region adjacent the Schottky contact. The JBS regions have a second conductivity type opposite the first conductivity type and have a first spacing between adjacent ones of the JBS regions. The device further includes a plurality of surge protection subregions having the second conductivity type. Each of the surge protection subregions has a second spacing between adjacent ones of the surge protection subregions that is less than the first spacing. |
