    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: Embodiments of the present invention include heterogeneous substrates, integrated circuits formed on such heterogeneous substrates, and methods of forming such substrates and integrated circuits. The heterogeneous substrates according to certain embodiments of the present invention include a first Group IV semiconductor layer (e.g., silicon), a second Group IV pattern (e.g., a silicon-germanium pattern) that includes a plurality of individual elements on the first Group IV semiconductor layer, and a third Group IV semiconductor layer (e.g., a silicon epitaxial layer) on the second Group IV pattern and on a plurality of exposed portions of the first Group IV semiconductor layer. The second Group IV pattern may be removed in embodiments of the present invention. In these and other embodiments of the present invention, the third Group IV semiconductor layer may be planarized.
