Claim 16:
17. A semiconductor device, comprising:
a first semiconductor layer including a first region and a second region;
a buried insulating layer on the first semiconductor layer in the first region;
a second semiconductor layer on the buried insulating layer;
a base layer on the first semiconductor layer in the second region;
a plurality of first channel layers on the second semiconductor layer, the plurality of first channel layers being spaced apart from one another in a vertical direction;
a first gate electrode surrounding the plurality of first channel layers;
a plurality of second channel layers on the base layer, the plurality of second channel layers being spaced apart from one another in the vertical direction; and
a second gate electrode surrounding the plurality of second channel layers,
wherein the first semiconductor layer has a first crystallographic orientation, and the second semiconductor layer has a second crystallographic orientation different from the first crystallographic orientation, and
wherein the plurality of second channel layers have the first crystallographic orientation.
