  • SUPER-STEEP SWITCHING DEVICE AND INVERTER DEVICE USING THE SAME
    Publication number: 20240096888
    Abstract: A super-steep switching device and an inverter device using the same are disclosed. The super-steep switching device includes a semiconductor channel disposed on a substrate and made of a semiconductor material having impact ionization characteristic; a source electrode and a drain electrode in contact with the semiconductor channel, wherein the source electrode and the drain electrode are disposed on the substrate and are spaced apart from each other; and a gate electrode disposed on the semiconductor channel so as to overlap only a portion of the semiconductor channel, wherein a top surface of the semiconductor channel includes a first area overlapping the gate electrode, and a second area non-overlapping the gate electrode, wherein a ratio of a length of the first area and a length of the second area is in a range of 1:0.1 to 0.4.
