Abstract:
A method of manufacturing a low capacitance density, high voltage MIM capacitor and the high density MIM capacitor. The method includes depositing a plurality of plates and a plurality of dielectric layers interleaved with one another. The method further includes etching a portion of an uppermost plate of the plurality of plates while protecting other portions of the uppermost plate. The protected other portions of the uppermost plate forms a top plate of a first metal-insulator-metal (MIM) capacitor and the etching exposes a top plate of a second MIM capacitor.
