Abstract

An MOS device has source and drain regions of a first conductivity formed in a well of a second conductivity, the well of the second conductivity being formed in an upper surface of a bulk material of the first conductivity. Source and drain potentials are applied to the source and drain regions, respectively, while a separate bias potential is routed to the well through a conductive sub-surface layer of the second conductivity which is located spaced from and beneath an upper surface of the bulk material and which is shorted to the well.
