text: A field effect transistor including a first region of semiconductive material of one conductivity type, source and drain connections spaced apart on one surface of said region, a second region of semiconductive material of opposite conductivity type disposed on the same surface between said source and drain connections` and forming a first junction with a limited area of said first region, a gate connection to said second reg-ion, a support of semiconductive material of opposite conductivity type serving to support said first region and forming a second junction with the other surface of the same, said second junction having a concentration gradient substantially smaller than that of the first junction, and means for reverse biasing said second junction to isolate the support from the first region.
