    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: 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.

    摘要: A cleaning solution and methods of fabricating semiconductor devices using the same are provided. 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. The cleaning solution may be used Lo clean a silicon surface exposed during fabrication processes of a semiconductor device. The cleaning solution may reduce damage of other material layers (e.g., a tungsten layer or a silicon oxide layer) and enable the silicon surface to be selectively etched.

    摘要: A cleaning solution selectively removes a titanium nitride layer and a non-reacting metal layer. The cleaning solution includes an acid solution and an oxidation agent with iodine. The cleaning solution also effectively removes a photoresist layer and organic materials. Moreover, the cleaning solution can be employed in tungsten gate electrode technologies that have been spotlighted because of the capability to improve device operation characteristics.
