    摘要: Methods of fabricating a semiconductor integrated circuit having thin film transistors using an SEG technique are provided. The methods include forming an inter-layer insulating layer on a single-crystalline semiconductor substrate. A single-crystalline semiconductor plug extends through the inter-layer insulating layer, and a single-crystalline epitaxial semiconductor pattern is in contact with the single-crystalline semiconductor plug on the inter-layer insulating layer. The single-crystalline epitaxial semiconductor pattern is at least partially planarized to form a semiconductor body layer on the inter-layer insulating layer, and the semiconductor body layer is patterned to form a semiconductor body. As a result, the semiconductor body includes at least a portion of the single-crystalline epitaxial semiconductor pattern. Thus, the semiconductor body has an excellent single-crystalline structure. Semiconductor integrated circuits fabricated using the methods are also provided.

    摘要: A nonvolatile memory device includes a semiconductor substrate having a first well region of a first conductivity type, and at least one semiconductor layer formed on the semiconductor substrate. A first cell array is formed on the semiconductor substrate, and a second cell array formed on the semiconductor layer. The semiconductor layer includes a second well region of the first conductivity type having a doping concentration greater than a doping concentration of the first well region of the first conductivity type. As the doping concentration of the second well region is increased, a resistance difference may be reduced between the first and second well regions.
