Abstract

A semiconductor device includes: an active pattern on a substrate, wherein the active pattern includes a plurality of channel layers stacked on one another; a plurality of source/drain patterns spaced apart from each other in a first direction and disposed on the active pattern, wherein the plurality of source/drain patterns are connected to each other through the plurality of channel layers; and first and second gate electrodes at least partially surrounding the channel layers and extending in a second direction, wherein the second direction intersects the first direction, wherein the active pattern has a first sidewall and a second sidewall that faces the first sidewall, and wherein a first distance between the first sidewall of the active pattern and an outer sidewall of the first gate electrode is different from a second distance between the second sidewall of the active pattern and an outer sidewall of the second gate electrode.
