    摘要: A method is provided for fabricating a dual damascene structure on a substrate with a first dielectric layer, an etching stop layer, a second dielectric layer, and a hard mask layer formed on it. The first step is to define the hard mask layer in order to form the first hole, which corresponds to the position of the conductive layer exposing the second dielectric layer. Then, an etching process, including an etching step with medium SiO.sub.2 /SiN etching selectivity and an over-etching step with high SiO.sub.2 /SiN etching selectivity, is performed to form the second hole and the third hole. Finally, a glue/barrier layer and a metal layer are filled into the second hole and the third hole, thus accomplishing a dual damascene structure.

    摘要: A method of fabricating an unlanded metal via of multi-level interconnection. The method is characterized by utilizing damascene scheme to form a metal wiring layer so that the processes are simplified. Moreover, by this method of the invention, a problem of difficulty in filling dielectric material between the metal wiring lines can be avoided and the metal layer does not have to be etched prior to filling the dielectric material. Further more, an etching stop layer is formed over the first inter-metal dielectric layer to avoid overetching during the formation of metal via, which therefore avoid short circuit. Forming the metal wiring lines by damascene scheme allows the etching stop layer to be easily formed over the first dielectric layer, without over etching the metal via.

    摘要: A method of forming a dual damascene structure comprises the steps of providing a substrate having a first conductive layer formed thereon, and then sequentially forming a first dielectric layer, an anti-reflection layer and a second dielectric layer over the substrate. Next, the first dielectric layer, the anti-reflection layer and the second dielectric layer are patterned to form a first opening that exposes the conductive layer. Thereafter, the second dielectric layer is patterned to form a trench (or second opening) in a position above the first conductive layer. The trench and the first opening together form an opening of the dual damascene structure. Finally, a second conductive material is deposited into the opening and the trench to form conductive lines and the dual damascene structures.

    摘要: An improved dual damascene process for forming metal interconnects comprising the steps of providing a semiconductor substrate that has a conductive layer, a first dielectric layer and a first mask layer already formed thereon. The first dielectric layer is made from a low-k dielectric material. A first silicon oxynitride (SiON) layer is formed over the first mask layer. Next, the first silicon oxynitride layer is patterned, and then the first mask layer is etched using the first silicon oxynitride as a mask. Subsequently, a second dielectric layer and a second mask layer are formed over the first silicon oxynitride. The second dielectric layer can be made from a low-k dielectric material. Next, a second silicon oxynitride layer is formed over the second mask layer. Thereafter, the second silicon oxynitride layer is patterned, and then the second mask layer is etched using the second silicon oxynitride layer as a mask. Subsequently, using the second mask layer as a mask, the second dielectric layer is etched to form a metal wire opening. Etching continues down the metal wire opening to form a via opening in the first dielectric layer that exposes the conductive layer. Finally, metal is deposited into the metal wire opening and the via opening to form the dual damascene structure of this invention.
