Claim 13:
14. A semiconductor device, comprising:
a first semiconductor layer including a first region and a second region;
a plurality of first channel layers spaced apart from each other in a vertical direction on the first semiconductor layer in the first region;
a first gate electrode surrounding the plurality of first channel layers;
a plurality of second channel layers spaced apart from one another in the vertical direction on the first semiconductor layer in the second region; and
