    摘要: Example embodiments relate to a capacitor including p-type doped silicon germanium and a method of manufacturing the capacitor. The capacitor may include a lower electrode, a dielectric layer, an upper electrode, a barrier layer and a capping layer. The lower electrode may have a cylindrical shape. The dielectric layer may be on the lower electrode. The dielectric layer may have a uniform thickness. The upper electrode may be on the dielectric layer. The upper electrode may have a more uniform thickness. The capping layer may be on the upper electrode. The capping layer may include a silicon germanium layer doped with p-type impurities. The barrier layer may be between the upper electrode and the capping layer to prevent (or reduce) the p-type impurities from infiltrating into the dielectric layer.

    摘要: In accordance with a method of trench isolation, a first oxide layer is formed on a semiconductor substrate. A first conductive layer and a nitride layer are successively formed on the first oxide layer. The nitride layer, the first conductive layer and the first oxide layer are etched to form a nitride layer pattern, a first conductive layer pattern and an oxide layer pattern. A portion of the substrate adjacent to the first conductive layer pattern is etched to form a trench in the substrate. The trench is cured under dinitrogen monoxide (N2O) or nitrogen monoxide(NO) atmosphere. A second oxide layer is formed in the trench through an in-situ process.
