    摘要: In a method of manufacturing a semiconductor device such as a SONOS type semiconductor device, a trench is formed on a substrate. An isolation layer protruding from the substrate is formed to fill the trench. After a first layer is formed on the substrate, a preliminary second layer pattern is formed on the first layer. The preliminary second layer pattern has an upper face substantially lower than or substantially equal to an upper face of the isolation layer. A third layer is formed on the preliminary second layer and the isolation layer. A fourth layer is formed on the third layer. The fourth layer, the third layer, the preliminary second layer pattern and the first layer are partially etched to form a gate structure on the substrate. Source/drain regions are formed at portions of the substrate adjacent to the gate structure.

    摘要: In a method of forming a capacitor, a first mold layer pattern including a first insulating material may be formed on a substrate. The first mold layer pattern may have a trench. A supporting layer including a second insulating material may be formed in the trench. The second insulating material may have an etching selectivity with respect to the first insulating material. A second mold layer may be formed on the first mold layer pattern and the supporting layer pattern. A lower electrode may be formed through the second mold layer and the first mold layer pattern. The lower electrode may make contact with a sidewall of the supporting layer pattern. The first mold layer pattern and the second mold layer may be removed. A dielectric layer and an upper electrode may be formed on the lower electrode and the supporting layer pattern.
