    摘要: A patterning method and a method for fabricating a dual damascene opening are described, wherein the patterning method includes following steps. An organic layer, a silicon-containing mask layer and a patterned photoresist layer are formed on a material layer in sequence. The silicon-containing mask layer is removed using the patterned photoresist layer as a mask. A reactive gas is used for conducting an etching step so as to remove the organic layer with the silicon-containing mask layer as a mask, wherein the reactive gas contains no oxygen species. The material layer is removed using the organic layer as a mask, so that an opening is formed in the material layer. The organic layer is then removed.

    摘要: A semiconductor process is provided. First, a metal layer, a dielectric layer and a patterned hard mask layer are sequentially formed on a substrate. Thereafter, a portion of the dielectric layer is removed to form an opening exposing the metal layer. Afterwards, a cleaning solution is used to clean the opening. The cleaning solution includes a triazole compound with a content of 0.00275 to 3 wt %, sulfuric acid with a content of 1 to 10 wt %, hydrofluoric acid with a content of 1 to 200 ppm and water. The semiconductor process can reduce the possibility of having an incomplete turning on, a leakage or a short, so that the yield of the product is increased.

    摘要: A method for filling a metal is disclosed. First, a substrate is provided. The substrate includes a metal material layer, a dielectric layer covering the metal material layer and a hard mask layer covering the dielectric layer. The hard mask layer has at least one opening to expose the underlying dielectric layer. Second, a dry etching step is performed to etch the dielectric layer through the opening to remove part of the dielectric layer to expose the metal material layer and to form a recess and leave some residues in the recess. Then a cleaning step is performed to remove the residues and to selectively remove part of the hard mask to substantially enlarge the opening. Later, a metal fills the recess through the enlarged opening.
