    摘要: A field effect transistor includes a vertical fin-shaped semiconductor active region having an upper surface and a pair of opposing sidewalls on a substrate, and an insulated gate electrode on the upper surface and opposing sidewalls of the fin-shaped active region. The insulated gate electrode includes a capping gate insulation layer having a thickness sufficient to preclude formation of an inversion-layer channel along the upper surface of the fin-shaped active region when the transistor is disposed in a forward on-state mode of operation. Related fabrication methods are also discussed.

    摘要: Methods for forming semiconductor devices are provided. A semiconductor substrate is etched such that the semiconductor substrate defines a trench and a preliminary active pattern. The trench has a floor and a sidewall. An insulating layer is provided on the floor and the sidewall of the trench and a spacer is formed on the insulating layer such that the spacer is on the sidewall of the trench and on a portion of the floor of the trench. The insulating layer is removed on the floor of the trench and beneath the spacer such that a portion of the floor of the trench is at least partially exposed, the spacer is spaced apart from the floor of the trench and a portion of the preliminary active pattern is partially exposed. A portion of the exposed portion of the preliminary active pattern is partially removed to provide an active pattern that defines a recessed portion beneath the spacer. A buried insulating layer is formed in the recessed portion of the active pattern. Related devices are also provided.

    摘要: Integrated circuit devices are provided including a first single-crystalline layer and an insulating layer pattern on the first single-crystalline layer. The insulating layer pattern has an opening therein that partially exposes the first single-crystalline layer. A seed layer is in the opening. A second single-crystalline layer is on the insulating layer pattern and the seed layer. The second single-crystalline layer has a crystalline structure substantially the same as that of the seed layer. A transcription-preventing pattern is on the second single-crystalline layer and a third single-crystalline layer on the transcription-preventing pattern and the second single-crystalline layer. The transcription-preventing pattern is configured to limit transcription of defective portions in the second single-crystalline layer into the third single-crystalline layer.

    摘要: A method of forming a fin field effect transistor on a semiconductor substrate includes forming an active region in the substrate, forming an epitaxial layer on the active region, and removing a portion of the epitaxial layer to form a vertical fin on the active region. The fin has a width that is narrower than a width of the active region. Removing a portion of the epitaxial layer may include oxidizing a surface of the epitaxial layer and then removing the oxidized surface of the epitaxial layer to decrease the width of the fin. The epitaxial layer may be doped in situ before removing a portion of the epitaxial layer. The method further includes forming a conductive layer on a top surface and on sidewalls of the fin. Related transistors are also discussed.
