Abstract:
A method of forming an MIM capacitor having interdigitated capacitor plates. Metal and dielectric layers are alternately deposited in an opening in a layer of insulator material. After each deposition of the metal layer, the metal layer is removed at an angle from the side to form the capacitor plate. The side from which the metal layer is removed is alternated with every metal layer that is deposited. When all the capacitor plates have been formed, the remaining opening in the layer of insulator material is filled with dielectric material then planarized, followed by the formation of contacts with the capacitor plates. There is also an MIM capacitor structure having interdigitated capacitor plates.
