    摘要: Provided are an anionic surfactant-containing etching solution for removal of an oxide film, preparation methods thereof, and methods of fabricating a semiconductor device using the etching solution. The etching solution includes a hydrofluoric acid (HF), deionized water, and an anionic surfactant. The anionic surfactant is a compound in which an anime salt is added as a counter ion, as represented by R1—OSO3−HA+, R1—CO2−HA+,R1—PO42—(HA+)2,(R1)2—PO4—HA+, or R1—SO3—HA+ where R1 is a straight or branched hydrocarbon group of C4 to C22 and A is ammonia or amine. The etching solution provides a high etching selectivity ratio of an oxide film to a nitride film or a polysilicon film. Therefore, in a semiconductor device fabrication process such as a STI device isolation process or a capacitor formation process, when an oxide film is exposed together with a nitride film or a polysilicon film, the etching solution can be efficiently used in selectively removing only the oxide film.

    摘要: An apparatus for drying a substrate using the Marangoni effect is disclosed. The apparatus includes a rotatable supporting portion on which a substrate is placed. A first nozzle for supplying de-ionized water and a second nozzle for supplying isopropyl alcohol vapor are provided on the supporting portion. When the isopropyl alcohol vapor is supplied to the center of the substrate at the initial stage, the amount of alcohol that reaches the substrate is controlled by a controlling portion such that the amount of the second liquid gradually increases.

    摘要: Provided is a method of manufacturing a capacitor of a semiconductor device, which can prevent tilting or an electrical short of a lower electrode. In the method, a mesh-type bridge insulating layer is formed above the contact plug on a mold oxide layer. The mold oxide layer and the bridge insulating layer are etched to define an electrode region. The mold oxide layer is removed using an etching gas having an etch selectivity of 500 or greater for the mold oxide layer with respect to the bridge insulating layer.

    摘要: A transistor having a metal nitride layer pattern, etchant and methods of forming the same is provided. A gate insulating layer and/or a metal nitride layer may be formed on a semiconductor substrate. A mask layer may be formed on the metal nitride layer. Using the mask layer as an etching mask, an etching process may be performed on the metal nitride layer, forming the metal nitride layer pattern. An etchant, which may have an oxidizing agent, a chelate agent and/or a pH adjusting mixture, may perform the etching. The methods may reduce etching damage to a gate insulating layer under the metal nitride layer pattern during the formation of a transistor.

    摘要: In a method of manufacturing a shallow trench isolation (STI) structure using a HF vapor etching process according to some embodiments of the invention, a trench is formed in a semiconductor substrate. A buffer layer and a first insulating layer, which fill the trench, are formed. A portion of the first insulating layer is removed by performing an etching process using HF vapor, thereby removing a void existing in the first insulating layer. A second insulating layer filling the trench is formed on the etched first insulating layer. Other embodiments of the invention are described and claimed.
