Abstract

The present disclosure relates to a MIM (metal-insulator-metal) capacitor having a top electrode overlying a substrate. A passivation layer overlies the top electrode. The passivation layer has a step region that continuously contacts and extends from a top surface of the top electrode to sidewalls of the top electrode. A metal frame overlies the passivation layer. The metal frame continuously contacts and extends from a top surface of the passivation layer to upper sidewalls of the passivation layer in the step region. The metal frame has a protrusion that extends through the passivation layer and contacts the top surface of the top electrode.
