  • Patent number: 11984353
    Abstract: The present disclosure, in some embodiments, relates to a method of forming a capacitor structure. The method includes forming a capacitor dielectric layer over a lower electrode layer, and forming an upper electrode layer over the capacitor dielectric layer. The upper electrode layer is etched to define an upper electrode and to expose a part of the capacitor dielectric layer. A spacer structure is formed over horizontally extending surfaces of the upper electrode layer and the capacitor dielectric layer and also along sidewalls of the upper electrode. The spacer structure is etched to remove the spacer structure from over the horizontally extending surfaces of the upper electrode layer and the capacitor dielectric layer and to define a spacer. The capacitor dielectric layer and the lower electrode layer are etched according to the spacer to define a capacitor dielectric and a lower electrode.

  • Publication number: 20240153987
    Abstract: The present disclosure relates to an integrated chip including a dielectric structure over a substrate. A first capacitor is disposed between sidewalls of the dielectric structure. The first capacitor includes a first electrode between the sidewalls of the dielectric structure and a second electrode between the sidewalls and over the first electrode. A second capacitor is disposed between the sidewalls. The second capacitor includes the second electrode and a third electrode between the sidewalls and over the second electrode. A third capacitor is disposed between the sidewalls. The third capacitor includes the third electrode and a fourth electrode between the sidewalls and over the third electrode. The first capacitor, the second capacitor, and the third capacitor are coupled in parallel by a first contact on a first side of the first capacitor and a second contact on a second side of the first capacitor.

  • Publication number: 20230307492
    Abstract: In some embodiments, the present application provides an integrated chip (IC). The IC includes a metal-insulator-metal (MIM) device disposed over a substrate. The MIM device includes a plurality of conductive plates that are spaced from one another. The MIM device further includes a first conductive plug structure that is electrically coupled to a first conductive plate and to a third conductive plate of the plurality of conductive plates. A first plurality of insulative segments electrically isolate a second conductive plate and a fourth conductive plate from the first conductive plug structure. The MIM device further includes a second conductive plug structure that is electrically coupled to the second conductive plate and to the fourth conductive plate of the plurality of conductive plates. A second plurality of insulative segments electrically isolate the first conductive plate and the third conductive plate from the second conductive plug structure.
