  • Patent number: 11521965
    Abstract: Junction field effect transistors (JFETs) and related manufacturing methods are disclosed herein. A disclosed four terminal JFET includes an integrated high voltage capacitor (HVC). The JFET includes a first terminal coupled to a drain region, a second terminal coupled to the source region, a third terminal coupled to the base region, and an integrated HVC terminal coupled to an integrated HVC electrode which forms an HVC with the drain region. The JFET also includes a channel formed by a channel region. A bias on the base region fully depletes the channel of majority carriers. The channel has an unbiased concentration of majority carriers. The integrated HVC electrode is positioned relative to the channel region such that applying the bias to the integrated HVC terminal depletes the channel by at most ten percent of the unbiased concentration of majority carriers.
