Abstract
A semiconductor device structure is provided. The semiconductor device structure includes a substrate having a base and a fin over the base. The semiconductor device structure includes a gate stack over a top portion of the fin. The semiconductor device structure includes a first nanostructure over the fin and passing through the gate stack. The semiconductor device structure includes a second nanostructure over the first nanostructure and passing through the gate stack. The first nanostructure is thicker than the second nanostructure. The semiconductor device structure includes a stressor structure over the fin and connected to the first nanostructure and the second nanostructure.
