    摘要: Lateral FET structure is disclosed for bidirectional power switching, including AC application. A notch extends downwardly from a top major surface to separate left and right source regions and left and right channel regions, and direct the drift region current path between the channels around the bottom of the notch. Split gate electrodes in the notch proximate the channels control bidirectional conduction, and are at non-common potentials in the OFF state to increase breakdown voltage. Self-shielding of the gates is also disclosed to further increase OFF state breakdown voltage.

    摘要: A lateral bidirectional power FET (2) has a common drift region (6) between first and second stacks (8, 10) of alternating conductivity type layers (12-17 and 18-23). A notch (38) extends vertically downwardly into the drift region and laterally separates the stacks above the drift region. The stacks include a plurality of channel-containing regions (12-14 and 18-20) interleaved with a plurality of source regions (15-17 and 21-23). In the ON state, bidirectional current flows serially through the source regions and channels of each stack and through the drift region. In the OFF state, voltage is dropped across the plurality of junctions in series in the stacks, and the respective junctions with the drift region.

    摘要: Lateral FET structure is disclosed for bidirectional power switching, including AC application. Voltage blocking capability is substantially increased by a shielding electrode insulated between first and second gate electrodes in a notch between laterally spaced source regions and channel regions joined by a common drift region around the bottom of the notch. The shielding electrode prevents the electric field gradient toward the gate electrode on one side of the notch from inducing depletion in the drift region along the opposite side of the notch. This prevents unwanted inducement of conduction channels in the drift region during the OFF state of the FET. High density, high voltage, plural FET structure is disclosed.
