Patent ID: 7670921

Claim:
A method of forming a metal-insulator-metal (MIM) capacitor, said method comprising: forming a first metallization layer in a first dielectric layer; forming a first passivation layer on top of the first dielectric layer; forming a planar conductive layer above the first passivation layer; patterning and selectively removing portions of the planar conductive layer in designated areas to form a set of conductive features electrically coupled at one end; forming a second dielectric layer over the first passivation layer and enclosing the set of conductive features; patterning and selectively removing first portions of the second dielectric layer to expose the set of conductive features; conformally coating the set of conductive features and the partially exposed first passivation layer with a high dielectric constant coating; patterning and selectively removing second portions of the second dielectric layer to form vias; patterning and selectively removing third portions of the second dielectric layer to form trenches; performing a dual-Damascene process to form a second metallization layer in the trenches and vias and to form an upper conductive surface above the high dielectric constant coating disposed above the set of conductive features; and wherein the set of conductive features forms a lower electrode, and the upper conductive surface forms an upper electrode of the MIM capacitor.
