Zusammenfassung:A junction field-effect transistor containing a semiconductor region with an inner region is described. In addition, a first and a second connecting region, respectively, are disposed within the semiconductor region. The first connecting region has the same conductivity type as the inner region, but in a higher doping concentration. The second connecting region has the opposite conductivity type to that of the inner region. This reduces the forward resistance while at the same time maintaining a high reverse voltage strength.
