Abstract

Transistors including a buried channel layer intermediate to a source and a drain and a surface layer intermediate to the buried layer and a gate are operated so as to cause current between the source and the drain to flow predominately through the buried channel layer by applying a back-bias voltage to the transistor. The back-bias voltage modulates a free charge carrier density distribution in the buried layer and in the surface layer.
