    摘要: A semiconductor device includes a lower pattern extending in a first direction and sheet patterns spaced apart therefrom in a second direction, a gate structure on the lower pattern and including a gate insulating layer, a gate spacer, and a gate electrode, a source/drain pattern on the lower pattern and in contact with the sheet patterns and the gate insulating layer, and a first etch blocking pattern between the gate spacer and the source/drain pattern. The gate spacer includes an inner sidewall extending in the third direction, and a connection sidewall extending from the inner sidewall in the first direction. The source/drain pattern includes a semiconductor filling layer on a semiconductor liner layer that is in contact with the sheet pattern and includes a facet surface extending from the connection sidewall. The first etch blocking pattern is in contact with the facet surface and the connection sidewall.

    摘要: A semiconductor device comprising a plurality of active patterns on a substrate. The semiconductor device may include a device isolation layer defining the plurality of active patterns, a gate electrode extending across the plurality of active patterns, and a source/drain pattern on the active patterns. The plurality of active patterns may comprise a first active pattern and a second active pattern. The source/drain pattern comprises a first part on the first active pattern, a second part on the second active pattern, and a third part extending from the first part and along an upper portion of the first active pattern. The device isolation layer comprises a first outer segment on a sidewall of the first active pattern below the source/drain pattern. A lowermost level of a bottom surface of the third part may be lower than an uppermost level of a top surface of the first outer segment.

    摘要: A semiconductor device is fabricated by providing a substrate including a silicon channel layer and a silicon-germanium channel layer, forming gate structures disposed on the silicon channel layer and on the silicon-germanium channel layer, forming a first protection layer to cover the resultant structure including the gate structures, and injecting hydrogen and/or its isotopes into the silicon-germanium channel layer. The silicon and silicon-germanium channel layers may be oriented along a direction. Related devices are also described.
