Classification: CPC H | IPC H

Claim 0:
1. An electronic device, comprising:
a semiconductor layer;
a first dielectric layer above the semiconductor layer;
a lower-bandgap dielectric layer above the first dielectric layer, the lower-bandgap dielectric layer having a bandgap energy less than a bandgap energy of the first dielectric layer;
a conductive first capacitor plate above the lower-bandgap dielectric layer in a first plane of orthogonal first and second directions;
a second dielectric layer above the first capacitor plate;
a conductive second capacitor plate above the second dielectric layer in a second plane of the first and second directions, the first and second capacitor plates spaced apart from one another along a third direction to form a first capacitor, the third direction orthogonal to the first and second directions; and
a conductive third capacitor plate above the second dielectric layer in the second plane, the third capacitor plate spaced apart from the second capacitor plate in the second plane, and the first and third capacitor plates spaced apart from one another along the third direction to form a second capacitor in series with the first capacitor.
