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.

Optionally, the stack also includes at least one additional capacitor (e.g., at metal-oxide-metal capacitor (MOMCAP)) on a dielectric layer aligned above the transistor-type capacitor (e.g., in one or more back end of the line (BEOL) metal levels).

A capacitor structure includes a bottom electrode, a top electrode, and a multilayer stack disposed between the bottom electrode and the top electrode.

The capacitor device includes first and second electrodes spaced apart from each other, and a dielectric layer provided between the first electrode and the second electrode. The dielectric layer includes a dielectric material in which ferroelectrics and antiferroelectrics are mixed with each other.
