ABSTRACT:
A monolithic switching device including a main semiconductor region configured to provide a current-carrying channel as in the form of two-dimensional electron gas. Disposed symmetrically on a surface of the main semiconductor region are two main electrodes to be coupled to an electric circuit for switching control, two gate electrodes for individually controlling current flow between the main electrodes through the current-carrying channel, and two diode-forming electrodes electrically connected respectively to the two main electrodes. The device operates in either Switch On Mode, Switch Off Mode, Negative Current Mode, or Positive Current Mode depending upon voltages applied to the two gate electrodes.
