Normally-off semiconductor switches and normally-off JFETs

摘要

A normally-off JFET is provided. The normally-off JFET includes a channel region of a first conductivity type, a floating semiconductor region of a second conductivity type adjoining the channel region, and a contact region of the first conductivity type adjoining the floating semiconductor region. The floating semiconductor region is arranged between the contact region and the channel region. Further, a normally-off semiconductor switch is provided.
