Abstract

A semiconductor device is provided including an active pattern disposed on a substrate, a source/drain pattern on the active pattern, a channel pattern configured to electrically connect the source/drain patterns and including stacked semiconductor patterns spaced apart from each other in a first direction perpendicular to an upper surface of the substrate, a gate pattern configured to cross between the source/drain patterns in a second direction parallel to the upper surface of the substrate, on the channel pattern, and to have a main gate portion and sub-gate portions, and inner gate spacers between the sub-gate portions and the source/drain pattern. A first distance between adjacent source/drain patterns along a given one of the sub-gate portions in the second direction is greater than a second distance between adjacent source/drain patterns passing through the semiconductor patterns in the second direction.
