Abstract: A chemical-mechanical polishing process includes the steps of providing a semiconductor substrate having a first conductive line thereon, and then forming at least one dielectric layer over the substrate and the first conductive line. Next, a chemical-mechanical polishing method is used to polish the surface of the dielectric layer. Thereafter, a cap layer is formed over the polished dielectric layer. The method of forming the cap layer includes depositing silicon oxide using a chemical vapor deposition method with silicane (SiH4) or tetra-ethyl-ortho-silicate (TEOS) as the main reactive agent. Alternatively, the cap layer can be formed by depositing silicon nitride using a chemical vapor deposition method with silicane or silicon dichlorohydride (SiH2Cl2) as the main reactive agent. Finally, a via opening is formed through the dielectric layer and the cap layer, and a second conductive line that couples electrically with the first conductive line through the via opening.

The semiconductor has a substrate, a first dielectric layer positioned on the substrate, a dual damascene hole positioned in the first dielectric layer through to the surface of the substrate, a barrier layer covering the surface of the first dielectric layer and both the surface of the walls and bottom of the dual damascene hole, and a copper layer positioned on the barrier layer and filling the dual damascene hole to form the dual damascene structure. The method first involves performing a first chemical mechanical polishing (CMP) process to remove portions of the copper layer down to the surface of the barrier layer. A photoresist layer is then formed atop the dual damascene structure to remove portions of the barrier layer uncovered by the photoresist layer.

Abstract: A method for forming capacitor is proposed. The key point of the invention is that bottom plate and dielectric layer of capacitor are formed before metal interconnect is formed. Thus, thermal treatment of dielectric layer does not affect metal interconnect. Therefore, conventional fault that quality of dielectric layer is degraded by scant annealing is avoided, and then dielectric layer and metal interconnect can be optimized respectively. Obviously, the ultimate advantage of the proposed method is that not only breakdown voltage of dielectric layer is increased by annealing but also quality of metal interconnect is not affected by annealing. Therefore, an incidental advantage of the proposed method is that the method is beneficial to form both capacitor and metal interconnect.
