    摘要: A conductive contact plug extends through an opening in the dielectric layer to contact the substrate and includes a widened pad portion extending onto the dielectric layer adjacent the opening. An ohmic pattern is disposed on the pad portion of the plug, and a barrier pattern is disposed on the ohmic pattern. A concave first capacitor electrode is disposed on the barrier pattern and defines a cavity opening away from the substrate. A capacitor dielectric layer conforms to a surface of the first capacitor electrode and a second capacitor electrode is disposed on the capacitor dielectric layer opposite the first capacitor electrode. Sidewalls of the ohmic pattern, the barrier pattern and the pad portion of the contact plug may be substantially coplanar, and the device may further include an etch stopper layer conforming to at least sidewalls of the ohmic pattern, the barrier pattern and the pad portion of the contact plug. Related fabrication methods are described.

    摘要: Trench capacitors that have insulating layer collars in undercut regions and methods of fabricating such trench capacitors are provided. Some methods of fabricating a trench capacitor include forming a first layer on a substrate. A second layer is formed on the first layer opposite to the substrate. A mask is formed that has an opening on top of the first and second layers. A first trench is formed by removing a portion of the first and second layers through the opening in the mask. A portion of the first layer under the second layer is removed to form an undercut region under the second layer. An insulating layer collar is formed in the undercut region under the second layer. A second trench is formed that extends from the first trench by removing a portion of the substrate through the opening in the mask. A buried plate is formed in the substrate along the second trench. A dielectric layer is formed on an inner wall and bottom of the second trench. A storage electrode is formed in the second trench on the dielectric layer.

    摘要: In a method of forming a thin film using an atomic layer deposition (ALD) method, a thin film is formed on a substrate in cycles. Each cycle includes injecting a first reactant including an atom that forms the thin film and a ligand into a reaction chamber that includes the substrate, purging the first reactant, injecting a second reactant into the reaction chamber, and purging the second reactant. The thin film is formed by a chemical reaction between the atom that forms the thin film and a second reactant whose binding energy with respect to the atom that forms the thin film is larger than the binding energy of the ligand with respect to the atom that forms the thin film and the generation of by-products is prevented. The generation of a hydroxide by-product in the thin film is suppressed by using a material that does not include a hydroxide as the second reactant, purging the second reactant, and reacting the second reactant with a third reactant that includes hydroxide. After purging the second reactant, the third reactant for removing impurities and improving the stoichiometry of the thin film is injected and purged. In this way, it is possible to obtain a thin film that does not include impurities and whose stoichiometry is excellent.

    摘要: A method of forming a metal thin film can reduce leakage current while improving electric properties by improving step coverage of a device. The method of forming a metal thin film includes supplying a metal precursor including chlorine, purging byproducts produced after the supplying of the metal precursor by injecting a purge gas, supplying a reactant to allow the reactant and the metal precursor to react with each other to form a thin film layer, and purging the byproducts produced after the reaction by injecting a purge gas, wherein before the supplying of the metal precursor, the method further includes supplying a reactant to be adsorbed on a treated product.
