Abstract: A semiconductor device includes a multi-channel active pattern, a plurality of gate structures on the multi-channel active pattern and spaced apart from each other in a first direction, the plurality of gate structures including a gate electrode that extends in a second direction different from the first direction, a source/drain recess between the adjacent gate structures, and a source/drain pattern on the multi-channel active pattern in the source/drain recess, wherein the source/drain pattern includes: a semiconductor liner layer including silicon-germanium and extending along the source/drain recess, a semiconductor filling layer including silicon-germanium on the semiconductor liner layer, and at least one or more semiconductor insertion layers between the semiconductor liner layer and the semiconductor filling layer, and wherein the at least one or more semiconductor insertion layers have a saddle structure.

Abstract: According to one embodiment, a method by which a device provides a service so as to enable cognitive function rehabilitation by using a virtual object model comprises the steps of: generating a virtual object model in a virtual space matched to correspond to a real space where a subject is located; generating a plurality of first preliminary stimuli for identifying egocentric neglect in the visual range of the subject on the basis of the virtual object model; obtaining and collecting first reaction information about whether the subject has recognized the first preliminary stimuli; determining an egocentric cognition range in which the subject can egocentrically recognize visual stimuli on the basis of the first reaction information; sequentially generating a plurality of second preliminary stimuli for identifying allocentric neglect in the egocentric cognition range on the basis of the virtual object model; obtaining and collecting second reaction information about whether the subject has recognized the secon
