    Abstract: A semiconductor device includes an active pattern provided on a substrate, a source/drain pattern provided on the active pattern, a channel pattern configured to be connected to the source/drain pattern, a gate electrode configured to be extended in a first direction and to cross the channel pattern, and a first spacer provided on a side surface of the gate electrode. The first spacer includes a fence portion provided on a side surface of the active pattern and below the source/drain pattern. The source/drain pattern includes a body portion and a neck portion between the body portion and the active pattern. The body portion includes a crystalline surface configured to be slantingly extended from the neck portion. The crystalline surface is configured to be spaced apart from an uppermost portion of the fence portion.

    Abstract: A semiconductor device includes: an active pattern disposed on a substrate; a source/drain pattern disposed on the active pattern; a channel pattern connected to the source/drain pattern, wherein the channel pattern includes semiconductor patterns stacked on each other and spaced apart from each other; and a gate electrode disposed on the channel pattern and extending in a first direction, wherein the gate electrode includes: a channel neighboring part adjacent to a first sidewall of a first semiconductor pattern of the stacked semiconductor patterns; and a body part spaced apart from the first semiconductor pattern, wherein the channel neighboring part is disposed between the body part and the first semiconductor pattern, wherein the first sidewall of the first semiconductor pattern has a first width, wherein the channel neighboring part has a second width less than the first width. The body part has a third width greater than the second width.
