Abstract: A substrate treating apparatus and a substrate treating system including the same are disclosed, in which the number of heat treatment chambers such as anneal chambers may be varied. The substrate treating apparatus includes a first chamber heat-treating a substrate; and a second chamber treating the substrate in another way different from heat-treatment, wherein the number of the first chambers is varied depending on the number of the second chambers that need heat treatment for the substrate.

Abstract: Method and apparatus for etching a thin layer including silicon nitride formed on a substrate are disclosed. Etchant including phosphoric acid and water is supplied on the substrate so that a liquid layer is formed on the substrate. The thin layer is etched by reaction between the thin layer and the etchant. Thickness of the liquid layer is measured to detect variation in the thickness of the liquid layer while etching the thin layer. Variation in the concentration of the phosphoric acid and the water is calculated based on the variation in the thickness of the liquid layer. Water is supplied on the substrate based on the variation in the concentration of the phosphoric acid and the water so that the concentration of the phosphoric acid and the water becomes a predetermined value.

Abstract: A method of fabricating a semiconductor device with improved electrical characteristics and reliability is provided. The method of fabricating the semiconductor device includes providing a substrate, in which a first oxide film, a nitride film, and a second oxide film are sequentially stacked, and a trench penetrating the first oxide film, the nitride film, and the second oxide film is formed, chamfering the oxide film exposed by the trench while removing a part of the nitride film exposed by the trench by using a first plasma process, and removing the nitride film left after the first plasma process by using a second plasma process.
