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.

A trench isolation in a semiconductor device, and a method for fabricating the same, includes: forming a trench having inner sidewalls for device isolation in a silicon substrate; forming an oxide layer on a surface of the silicon substrate that forms the inner sidewalls of the trench; supplying healing elements to the silicon substrate to remove dangling bonds; and filling the trench with a device isolation layer, thereby forming the trench isolation without dangling bonds causing electrical charge traps.

Fin FET semiconductor devices are provided which include a substrate, an active pattern that protrudes vertically from the substrate and that extends laterally in a first direction, a device isolation layer which has a top surface that is lower than a top surface of the active pattern, a gate structure on the substrate that extends laterally in a second direction to cover a portion of the active pattern and a conductive layer that is on at least portions of side surfaces of the active pattern that are adjacent a side portion of the gate structure. The conductive layer may comprise a semiconductor layer, and the semiconductor layer may be in electrical contact with a contact pad. In other embodiments, the conductive layer may comprise a contact pad.

A semiconductor device may have a structure that prevents or reduces an etching amount of certain portions, such as a part of a source/drain region. Adjacent active fins may be merged with a blocking layer extending between adjacent the source/drain region. The blocking layer may be of a material that is relatively high-resistant to the etchant.

A method of manufacturing a semiconductor device includes forming first and second gate structures on a substrate in first and second regions, respectively, forming a first capping layer on the substrate by a first high density plasma process, such that the first capping layer covers the first and second gate structures except for sidewalls thereof, removing a portion of the first capping layer in the first region, removing an upper portion of the substrate in the first region using the first gate structure as an etching mask to form a first trench, and forming a first epitaxial layer to fill the first trench.
