Patent ID: 8143699

Claim:
An integrated circuit structure comprising: a chip comprising a first region and a second region; a first metal-insulator-metal (MIM) capacitor in the first region, wherein the first MIM capacitor comprises: a first bottom electrode; a first top electrode over the first bottom electrode; and a first capacitor insulator between and adjoining the first bottom electrode and the first top electrode; and a second MIM capacitor in the second region and substantially level with the first MIM capacitor, wherein the second MIM capacitor comprises: a second bottom electrode; a second top electrode over the second bottom electrode; and a second capacitor insulator between and adjoining the second bottom electrode and the second top electrode, wherein the second capacitor insulator is different from the first capacitor insulator, with the first capacitor insulator having a different thickness than the second capacitor insulator, or the first capacitor insulator and the second capacitor insulator comprising different materials.
