Classification: CPC H  B | IPC H

Claim 0:
1. A semiconductor device, comprising:
a plurality of semiconductor layers vertically separated from one another, wherein each of the plurality of semiconductor layers extends along a first lateral direction; and
a gate structure that extends along a second lateral direction and comprises at least a lower portion that wraps around each of the plurality of semiconductor layers;
wherein the lower portion of the gate structure includes:
a plurality of first gate sections, each of the first gate sections having a first curvature-based profile when viewed from its cross-section expanding over the first and second lateral directions; and
a plurality of second gate sections, each of the second gate sections having a second, different curvature-based profile when viewed from its cross-section expanding over the first and second lateral directions.
