    摘要: For planarizing an IC (integrate circuit) material, a first slurry is dispensed for a first planarization of the IC material using the first slurry, and a second slurry is dispensed for a second planarization of the IC material using the second slurry. The first and second slurries are different. For example, the first slurry is silica based for faster planarization during the first planarization. Thereafter, the second planarization is performed with the second slurry that is ceria based with higher planarity for attaining sufficient planarization of the IC material.

    摘要: A semiconductor device and a method thereof are disclosed. In the example method, a mold layer having an opening may be formed on a substrate. A conductive etchable pattern (e.g., a preliminary conductive pattern, a lower electrode pattern, etc.) may be formed within the opening. The mold layer may be reduced so as to expose a portion of the conductive etchable pattern and less than all of the exposed portion of the conductive etchable pattern may be etched such that the etched conductive etchable pattern has a reduced thickness. The example semiconductor device may include the etched conductive etchable pattern as above-described with respect to the example method.

    摘要: In a slurry composition preventing damage to an insulation layer, and uniformly polishing a metal layer, the slurry composition includes an acidic aqueous solution having a first pH and an anionic surfactant having a second pH lower than or equal to the first pH. Irregular polishing of the metal layer relative to a pattern density may be prevented and a contact having a uniform thickness may be formed using the slurry composition.

    摘要: An isolation layer having a first depth is formed from an upper face of a substrate. Source/drain regions including junctions are formed in the substrate. Each of the junctions has a second depth substantially smaller than the first depth. A first recess is formed in the substrate by a first etching process. A protection layer pattern is formed on a sidewall of the first recess. A second recess is formed beneath the first recess. The second recess has a width substantially larger than that of the first recess. The second recess is formed by a second etching process using an etching gas containing an SF6 gas, a Cl2 gas and an O2 gas. A gate insulation layer is formed on surfaces of the first and the second recesses. The second recess having an enlarged shape may reduce a width of the junction between the gate electrode and the isolation layer so that a leakage current generated through the junction may decrease.
