Claim Text:
1. A method for fabricating, within an integrated circuit (IC), a capacitor, the method comprising: creating, in a top surface of a dielectric layer of the IC, a recess having at least one side and a bottom, the bottom adjacent to a first conductive structure; forming a first plate of the capacitor by depositing a first conductive liner onto the at least one side and the bottom of the recess; depositing a conformal dielectric film onto the first plate within the recess and covering the entire upper surface of the dielectric layer, the conformal dielectric being HfO forming a second plate of the capacitor by completely covering a portion of the conformal dielectric film within the recess with an electrically conductive material that is electrically insulated, by the conformal dielectric film, from the first plate; and wherein the second plate is planar with the uppermost surface of the conformal dielectric film.
