    摘要: A semiconductor manufacturing process is provided. First, a substrate is provided, wherein a patterned conductive layer, a dielectric layer and a patterned metal hard mask layer are sequentially formed thereon. Thereafter, a portion of the dielectric layer is removed to form a damascene opening exposing the patterned conductive layer. Afterwards, the dielectric layer is heated to above 200° C. Thereafter, a plasma treatment process is performed on the damascene opening, wherein the gases used to generate the plasma include hydrogen gas and inert gas. Afterwards, a conductive layer is formed in the damascene opening to fill therein.

    摘要: A method for forming an opening on a material layer is provided. First, a dielectric layer is formed on the material layer. Then, a metallic hard mask layer and a cap layer are sequentially formed on the dielectric layer. Thereafter, a patterned photoresist layer is formed on the cap layer. The patterned photoresist layer exposes a portion of the surface of the cap layer. After that, a first etching operation is carried out using the patterned photoresist layer as a mask to remove a portion of the cap layer and the metallic hard mask layer until the surface of the dielectric layer is exposed. Then, the photoresist layer is removed. A second etching operation is carried out using the cap layer and the metallic hard mask layer as a mask to remove a portion of the dielectric layer and form an opening.
