    摘要: In a fin field effect transistor (FET), an active pattern protrudes in a vertical direction from a substrate and extends across the substrate in a first horizontal direction. A first silicon nitride pattern is formed on the active pattern, and a first oxide pattern and a second silicon nitride pattern are sequentially formed on the substrate and on a sidewall of a lower portion of the active pattern. A device isolation layer is formed on the second silicon nitride pattern, and a top surface of the device isolation layer is coplanar with top surfaces of the oxide pattern and the second silicon nitride pattern. A buffer pattern having an etching selectivity with respect to the second silicon nitride pattern is formed between the first oxide pattern and the second silicon nitride pattern. Internal stresses that can be generated in sidewalls of the active pattern are sufficiently released and an original shape of the first silicon nitride pattern remains unchanged, thereby improving electrical characteristics of the fin FET.

    摘要: In a method of manufacturing a stacked semiconductor device, a seed layer including impurity regions may be prepared. A first insulation interlayer pattern having a first opening may be formed on the seed layer. A first SEG process may be carried out to form a first plug partially filling the first opening. A second SEG process may be performed to form a second plug filling the first opening. A third SEG process may be carried out to form a first channel layer on the first insulation interlayer pattern. A second insulation interlayer may be formed on the first channel layer. The second insulation interlayer, the first channel layer and the second plug arranged on the first plug may be removed to expose the first plug. The first plug may be removed to form a serial opening. The serial opening may be filled with a metal wiring.

    摘要: A fin type field effect transistor includes a semiconductor substrate, an active fin, a first hard mask layer pattern, a gate insulation layer pattern, a first conductive layer pattern, and source/drain regions. The active fin includes a semiconductor material and is formed on the substrate and extends in a direction away from a major surface of the substrate. The first hard mask layer pattern is formed on a distal surface of the active fin from the substrate. The gate insulation layer is formed on a sidewall portion of the active fin. The first conductive layer pattern includes a metal silicide and is formed on surfaces of the substrate and the gate insulation layer pattern, and on a sidewall of the first hard mask pattern. The source/drain regions are formed in the active fin on opposite sides of the first conductive layer pattern.

    摘要: In a method of forming a thin-film structure employed in a non-volatile semiconductor device, an oxide film is formed on a substrate. An upper nitride film is formed on the oxide film by nitrifying an upper portion of the oxide film through a plasma nitration process. A lower nitride film is formed between the substrate and the oxide film by nitrifying a lower portion of the oxide film through a thermal nitration process. A damage to the thin-film structure generated in the plasma nitration process may be at least partially cured in the thermal nitration process, and/or may be cured in a post-thermal treatment process.

    摘要: Methods of etching a semiconductor substrate may include providing a first gas that is chemically reactive with respect to the semiconductor substrate, and while providing the first gas, providing a second gas different than the first gas. More particularly, a molecule of the second gas may include a hydrogen atom, and the second gas may lower a temperature at which the first gas chemically reacts with the semiconductor substrate. The mixture of the first and second gases may be provided adjacent the semiconductor substrate to etch the semiconductor substrate.
