Abstract: A dual damascene process is provided on a semiconductor substrate, having a conductive structure and a low-k dielectric layer covering the conductive structure. A first hard mask and a second hard mask are sequentially formed on the low-k dielectric layer, in which at least the hard mask contacting the low-k dielectric layer is of metallic material. Next, a first opening is formed in the second hard mask over the conductive structure, and a second opening is then formed in the first hard mask under the first opening. Afterward, the low-k dielectric layer that is not covered by the first hard mask is removed, thus a via hole is formed. Thereafter, the first hard mask that is not covered by the second hard mask is removed, and then the exposed low-k dielectric layer is removed. Thereby, a trench is formed over the via hole.

Abstract: A capacitor in which the lower electrode and an interconnect line are located at the same level. The capacitor includes a first conductive line and a second conductive line on a substrate located at the same level, wherein the second conductive line defines a capacitor region and is used as a lower electrode of the capacitor; an insulating layer on the substrate, the first conductive line, and the second conductive line; and a third conductive line on the insulating layer in the capacitor region such that the third conductive line is used as an upper electrode of the capacitor. Since the lower electrode and an interconnect line can be in-situ (concurrently) formed to be located at the same level, one mask can be omitted compared with the conventional method, and production costs can be reduced.
