Abstract
A semiconductor device structure is provided. The semiconductor device structure includes a substrate and multiple nanostructures over the substrate. The semiconductor device structure also includes a semiconductor fin between the substrate and the nanostructures. The semiconductor device structure further includes a gate stack wrapped around the nanostructures. The gate stack includes a gate dielectric layer, and the gate dielectric layer continuously extends along a bottommost nanostructure of the nanostructures and an upper portion of the semiconductor fin.
