    摘要: Methods of forming metal nitride layers on a substrate include reacting a metal source gas with a nitrogen source gas in a process chamber to form a metal nitride layer on the substrate. The process chamber may have an atmosphere having a pressure of about 0.1 mTorr to about 5 mTorr and a temperature of about 200° C. to about 450° C. A ratio of the flow rate of the metal source gas to the flow rate of the nitrogen source gas may be “1” or more. An interlayer insulating layer may be formed on the semiconductor substrate prior to formation of the metal nitride layer. Some methods include forming a contact hole in the interlayer insulating layer to expose a portion of the semiconductor substrate prior to forming the metal nitride layer

    摘要: A method of fabricating an integrated circuit capacitor includes forming a first metal layer on a conductive plug in an interlayer insulating layer on a substrate. At least a portion of the first metal layer is silicided to form a metal silicide layer and a remaining first metal layer on the conductive plug. The remaining first metal layer is removed using a dry etching process. A lower electrode including a second metal layer is then formed on the metal silicide layer. Because the remaining first metal layer is removed, etching and/or other damage to the conductive plug and/or the interlayer insulating layer during a subsequent wet ethching process may be reduced and/or prevented.

    摘要: In an ohmic layer and methods of forming the ohmic layer, a gate structure including the ohmic layer and a metal wiring having the ohmic layer, the ohmic layer is formed using tungsten silicide that includes tungsten and silicon with an atomic ratio within a range of about 1:5 to about 1:15. The tungsten silicide may be obtained in a chamber using a reaction gas including a tungsten source gas and a silicon source gas by a partial pressure ratio within a range of about 1.0:25.0 to about 1.0:160.0. The reaction gas may have a partial pressure within a range of about 2.05 percent to about 30.0 percent of a total internal pressure of the chamber. When the ohmic layer is employed for a conductive structure, such as a gate structure or a metal wiring, the conductive structure may have a reduced resistance.

    摘要: In a method for forming a gate in a semiconductor device, a first preliminary gate structure is formed on a substrate. The first preliminary gate structure includes a gate oxide layer, a polysilicon layer pattern and a tungsten layer pattern sequentially stacked on the substrate. A primary oxidation process is performed using oxygen radicals at a first temperature for adjusting a thickness of the gate oxide layer to form a second preliminary gate structure having tungsten oxide. The tungsten oxide is reduced to a tungsten material using a gas containing hydrogen to form a gate structure. The tungsten oxide may not be formed on the gate structure so that generation of the whiskers may be suppressed. Thus, a short between adjacent wirings may not be generated.
