    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 a vertical fin protruding from the substrate. A buffer oxide liner is formed on a top surface and on sidewalls of the fin. A trench is then formed on the substrate, where at least a portion of the fin protrudes from a bottom surface of the trench. The trench may be formed by forming a dummy gate on at least a portion of the fin, forming an insulation layer on the fin surrounding the dummy gate, and then removing the dummy gate to expose the at least a portion of the fin, such that the trench is surrounded by the insulation layer. The buffer oxide liner is then removed from the protruding portion of the fin, and a gate is formed in the trench on the protruding portion of the fin.
