    摘要: A semiconductor device includes a semiconductor substrate having first and second regions therein, a first lower semiconductor pattern, which protrudes from the semiconductor substrate in the first region and extends in a first direction across the semiconductor substrate, and a first gate electrode, which extends across the first lower semiconductor pattern and the semiconductor substrate in a second direction. A plurality of semiconductor sheet patterns are provided, which are spaced apart from each other in a third direction to thereby define a vertical stack of semiconductor sheet patterns, on the first lower semiconductor pattern. A first gate insulating film is provided, which separates the plurality of semiconductor sheet patterns from the first gate electrode. A second lower semiconductor pattern is provided, which protrudes from the semiconductor substrate in the second region. A plurality of wire patterns are provided, which are spaced apart from each other on the second lower semiconductor pattern. A second gate insulating film is wrapped around each of the plurality of wire patterns.

    摘要: A semiconductor device comprises an active pattern on a substrate; a plurality of nanosheets spaced apart from each other; a gate electrode surrounding each of the nanosheets; a field insulating layer surrounding side walls of the active pattern; an interlayer insulating layer on the field insulating layer; a source/drain region comprising a first doping layer on the active pattern, a second doping layer on the first doping layer, and a capping layer forming side walls adjacent to the interlayer insulating layer; a source/drain contact electrically connected to, and on, the source/drain region, and a silicide layer between the source/drain region and the source/drain contact which contacts contact with the second doping layer and extends to an upper surface of the source/drain region. The capping layer extends from an upper surface of the field insulating layer to the upper surface of the source/drain region along side walls of the silicide layer.

    摘要: A method of fabricating a semiconductor device is provided. The method includes forming a dummy gate electrode on a substrate, forming a trench on a side surface of the dummy gate electrode, performing a bake process of removing an impurity from the trench and forming a source/drain in the trench, wherein the bake process comprises a first stage and a second stage following the first stage, an air pressure in which the substrate is disposed during the first stage is different from an air pressure in which the substrate is disposed during the second stage, and the bake process is performed while the substrate is on a stage rotating the substrate, wherein a revolution per minute (RPM) of the substrate during the first stage is different from a revolution per minute (RPM) of the substrate during the second stage.
