Beschreibung
Zusammenfassung:The invention relates to a stacked capacitor comprising a silicon base plate, a poly-silicon center plate arranged above the base plate, a lower gate-oxide dielectric arranged between the base plate and the center plate, a cover plate made of a metallic conductor and arranged above the center plate, and an upper dielectric arranged between the center plate and the cover plate. The cover plate and the base plate are electrically connected to each other and together form a first capacitor electrode. The center plate forms a second capacitor electrode. The invention further relates to an integrated circuit with such a stacked capacitor, as well as to a method for fabrication of a stacked capacitor as part of a CMOS process.
