摘要
A transistor with source and drain electrodes formed in contact with an active region and a gate between the source and drain electrodes and in contact with the active region. A first spacer layer is on at least part of the active region surface between the gate and drain electrodes and between the gate and source electrodes. The gate comprises a generally t-shaped top portion that extends toward the source and drain electrodes. A field plate is on the spacer layer and under the overhang of at least one section of the gate top portion. The field plate is at least partially covered by a second spacer layer that is on at least part of the first active layer surface and between the gate and drain and between the gate and source. At least one conductive path electrically connects the field plate to the source electrode or the gate.
