摘要: A method for forming contact openings is provided. First, a semiconductor device is formed on a substrate. Next, an etching stop layer, a first dielectric layer and a patterned photoresist layer are sequentially formed on the substrate. Next a portion of the first dielectric layer and a portion of the etching stop layer are removed to form an opening, wherein the portion of the first dielectric layer and the portion of the etching stop layer are not covered by the patterned photoresist layer. Next, the patterned photoresist layer is removed. Next, an over etching process is performed to remove the etching stop layer at a bottom of the opening and expose the semiconductor device in a nitrogen-free environment. The reactant gas of the over etching process includes fluorine-containing hydrocarbons, hydrogen gas and argon gas.
