CAPACITANCE NETWORKS FOR ENHANCING HIGH VOLTAGE OPERATION OF A HIGH ELECTRON MOBILITY TRANSISTOR AND METHOD THEREIN

Capacitance networks for enhancing high voltage operation of high electron mobility transistors (HEMTs) are presented herein. A capacitance network, integrated and/or external, may be provided with a fixed number of capacitively coupled field plates to distribute the electric field in the drift region. The capacitively coupled field plates may advantageously be fabricated on the same metal layer to lower cost; and the capacitance network may be provided to control field plate potentials. The potentials on each field plate may be pre-determined through the capacitance network, resulting in a uniform, and/or a substantially uniform electric field distribution along the drift region.
