Abstract: A semiconductor device including a well region in a substrate, an impurity region in the well region, a first active fin on the impurity region, a second active fin on the well region, and a connection pattern penetrating the second active fin and connected to the well region may be provided. The substrate and the impurity region include impurities having a first conductivity type. The well region includes impurities having a second conductivity type different from the first conductivity type. The first active fin includes a plurality of first semiconductor patterns that are spaced apart from each other in a direction perpendicular to a top surface of the substrate. The first semiconductor patterns and the impurity region include impurities having the first conductivity type.

Abstract: The semiconductor device may include an active pattern provided on a substrate and a source/drain pattern on the active pattern. The source/drain pattern may include a bottom surface in contact with a top surface of the active pattern. The semiconductor device may further include a channel pattern connected to the source/drain pattern, a gate electrode extended to cross the channel pattern, and a fence insulating layer extended from a side surface of the active pattern to a lower side surface of the source/drain pattern. A pair of middle insulating patterns may be at both sides of the bottom surface of the source/drain pattern and between the active pattern and the source/drain pattern in contact with an inner side surface of the fence insulating layer.
