Classification: CPC H  B | IPC H

Claim 0:
1. A semiconductor device, comprising:
nanostructures vertically arranged and spaced apart from one another along a first direction;
a dielectric fin structure of a dielectric material of uniform composition and an isolation structure on opposite sides of the nanostructures; and
a gate structure wrapping around the nanostructures, extending between the nanostructure and the dielectric fin structure, and extending between the nanostructures and the isolation structure,
wherein the nanostructures are spaced apart from the dielectric fin structure along a second direction perpendicular to the first direction by a first distance, and from the isolation structure along the second direction by a second distance, and the first distance is greater than the second distance, and
wherein the gate structure interfaces with the dielectric fin structure on a surface extending perpendicular to the first direction.
