    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: 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.
