Claim 19:
20. A semiconductor device, comprising:
a substrate, the substrate including an active region extending in a first direction;
a plurality of channel layers on the active region, the plurality of channel layers disposed in a direction perpendicular to an upper surface of the substrate;
a gate electrode respectively surrounding the plurality of channel layers, the gate electrode extending in a second direction crossing the first direction, the gate electrode including a first portion and a second portion on an uppermost channel layer of the plurality of channel layers, the first portion of the gate electrode being on the second portion of the gate electrode;
a semiconductor cap layer between the first portion of the gate electrode and the second portion of the gate electrode and having a same material as that of each of the plurality of channel layers; and
a source/drain structure disposed on at least one side of the gate electrode and connected to the plurality of channel layers, while the source/drain structure being not connected to the semiconductor cap layer.
