    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.

    摘要: In a method of forming an isolation layer, first and second trenches are formed on a substrate. The first and the second trenches have first and second widths, respectively, and the second width is greater than the first width. A second isolation layer pattern partially fills the second trench. A first isolation layer pattern and the third isolation layer pattern are formed. The first isolation layer pattern fills the first trench, and the third isolation layer pattern is formed on the second isolation layer pattern and fills a remaining portion of the second trench.
