Abstract:
Embedded memories. The devices include a substrate, a first dielectric layer, a second dielectric layer, a third dielectric layer, and a plurality of capacitors. The substrate comprises transistors. The first dielectric layer, embedding first and second conductive plugs electrically connecting the transistors therein, overlies the substrate. The second dielectric layer, comprising a plurality of capacitor openings exposing the first conductive plugs, overlies the first dielectric layer. The capacitors comprise a plurality of bottom plates, respectively disposed in the capacitor openings, electrically connecting the first conductive plugs, a plurality of capacitor dielectric layers respectively overlying the bottom plates, and a top plate, comprising a top plate opening, overlying the capacitor dielectric layers. The top plate opening exposes the second dielectric layer, and the top plate is shared by the capacitors.
