    摘要: A thin layer structure includes a substrate, a blocking pattern that exposes part of an upper surface of the substrate, and a single crystalline semiconductor layer on the part of the upper surface of the substrate exposed by the pattern and in which all outer surfaces of the single crystalline semiconductor layer have a crystallographic orientation. The thin layer structure is formed by an SEG process in which the temperature is controlled to prevent migration of atoms in directions towards the central portion of the upper surface of the substrate. Thus, sidewall surfaces of the layer will not be constituted by facets.

    摘要: Provided is a method of manufacturing a semiconductor device having a capacitor. The method includes forming a composite layer, including sequentially stacking on a substrate alternating layers of first through nth sacrificial layers and first through nth supporting layers. A plurality of openings that penetrate the composite layer are formed. A lower electrode is formed in the plurality of openings. At least portions of the first through nth sacrificial layers are removed to define a support structure for the lower electrode extending between adjacent ones of the plurality of openings and the lower electrode formed therein, the support structure including the first through nth supporting layers and a gap region between adjacent ones of the first through nth supporting layers where the first through nth sacrificial layers have been removed. A dielectric layer is formed on the lower electrode and an upper electrode is formed on the dielectric layer.
