Abstract:
Disclosed is a method for manufacturing a capacitor in a semiconductor device. A method consistent with the present invention includes forming a lower electrode on a semiconductor substrate; forming a first interlevel dielectric layer on an entire surface of the semiconductor substrate, covering the lower electrode; selectively removing the first interlevel dielectric layer to form an opening exposing a surface of the lower electrode; sequentially forming a dielectric layer and a conductive layer over the entire surface of the semiconductor substrate including the opening; planarizing the conductive layer to form an upper electrode in the opening; and forming a second interlevel dielectric layer over the entire surface of the semiconductor substrate including the upper electrode.
