Source sentences:
text: A field effect transistor including a first region of one conductivity type, source and drain connections spaced apart thereon, a second region of opposite conductivity type disposed between said source and drain connections and forming a junction with predetermined concentration gradient with said first region, a gate connection to said second region, a third region of opposite conductivity type serving to support said first region and forming a second junction therewith, said second junction having a concentration gradient substantially smaller than the concentration gradient junction between the first and second regions.
text: A field effect transistor including a first relatively thin region of semiconductive material of one conductivity type, source and drain connections spaced apart thereon, a second region of semiconductive material of opposite conductivity type disposed between said source and drain connections and forming a rectifying junction with said first region, a gate connection to said second region, and a support of semiconductive material of opposite conductivity type supporting said first region and forming a junction therewith, said support region having an impurity concentration which is less than that in the second region.
