Abstract:
A capacitor with metallic conducting electrodes as constructed in an integrated circuit intended for preferably high-frequency applications, comprising:a layer structure comprising lowermost a substrate and uppermost a first insulating layer;a lower electrode formed of a first metal layer and lying on the first insulating layer;a second insulating layer lying on the first metal layer and having a via hole and a capacitor opening provided therein, said second insulating layer also having a capacitor receiving predetermined area provided therein;an electric connection to the lower electrode in the shape of a plug provided in the via hole formed during a first conductive deposition step;a capacitor dielectric overlapping said predetermined area; andan upper electrode and a connection layer electrically connected to the plug and formed of a second metal layer lying over said second insulating layer, the plug and said capacitor dielectric, the second metal layer being formed during a second conductive deposition step different from the first conductive deposition step.
