    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: Example embodiments of the present invention relates to methods of fabricating a semiconductor device. Other example embodiments of the present invention relate to methods of fabricating a semiconductor device using a metal nitride layer as a gate electrode. The methods may include providing a semiconductor substrate having a first region and a second region. A gate insulating layer, a metal nitride layer and/or an amorphous carbon layer may be sequentially formed on the substrate. The amorphous carbon layer may be selectively etched, forming an amorphous carbon mask covering the first region. The metal nitride layer, exposed by the amorphous carbon mask, may be etched, forming a preliminary metal nitride pattern. The amorphous carbon mask may be removed.

A cleaning solution used for cleaning a silicon surface and methods of fabricating a semiconductor device using the same are also provided. The cleaning solution may include 0.01 to 1 wt % of fluoric acid, 20 to 50 wt % of oxidizer and 50 to 80 wt % of water. The cleaning solution may further include 1 to 20 wt % of acetic acid.
