Abstract:
1. A metal-insulator-metal (MIM), capacitor structure on a semiconductor substrate, comprising: a first metal connector structure located in a first opening in a first intermetallic dielectric (IMD)layer, with said first metal connector structure overlying and contacting portions of underlying, said semiconductor substrate; said MIM capacitor structure on top surface of said first IMD layer, and on top surface of said first metal connector structure, with said MIM capacitor structure comprised of an underlying capacitor bottom plate, a capacitor dielectric shape, and an overlying capacitor top plate; an insulator shape located only on top surface of said capacitor top plate; insulator spacers located on the sides of said insulator shape and on sides of said capacitor top plate, with said insulator spacers overlying edges of said capacitor dielectric shape; a second ILD layer overlying said insulator shape; a second opening in second ILD layer, and in said insulator shape, exposing a portion of the top surface of said capacitor top plate; and a second metal connector structure located in said second opening, overlying and contacting a portion of the top surface of said capacitor top plate.
