WIDE BANDGAP TRANSISTORS WITH GATE-SOURCE FIELD PLATES

摘要

A transistor comprising an active region having a channel layer, with source and drain electrodes formed in contact with the active region and a gate formed between the source and drain electrodes and in contact with the active region. A spacer layer is on at least part of the surface of the plurality of active region between the gate and the drain electrode and between the gate and the source electrode. A field plate is on the spacer layer and extends on the spacer and over the active region toward the drain electrode. The field plate also extends on the spacer layer over the active region and toward the source electrode. At least one conductive path electrically connects the field plate to the source electrode or the gate.
