Abstract
A high-voltage metal capacitor with easy integration into existing semiconductor manufacturing processes can provide isolation capacitors up to several kilovolts. The capacitor includes a support layer with internal structure, including a lower place, a bond pad on the support layer, an upper plate disposed on the support layer, the upper plate being arranged above the lower plate, a dielectric layer, at least part of which is between the lower and upper plates, and a passivation layer, at least part of which covers at least part of the upper plate and part of the dielectric layer. A first opening extends from the surface through the passivation and dielectric layers to the lower plate, and a second opening extends from the surface through the passivation layer to the upper plate. A method of manufacturing the capacitor.
