Abstract
Two series-connected metal-insulator-metal (MIM) capacitors are disclosed that are suitable for fabrication in the back-end structure of an integrated circuit. The MIM capacitors have first and second electrically conducting plates on a first insulating layer, third and fourth electrically conducting plates overlapping the first and second conducting plates, a second insulating layer between the first and third conducting plates and between the second and fourth conducting plates, a blind via coupling the first and fourth conducting plates, and connections to the second and third conducting plates. Methods of fabricating such series-connected MIM capacitors are also disclosed.
