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 structure wrapping around a top portion of the fin. The semiconductor device structure includes a first nanostructure over the fin and passing through the gate structure. The semiconductor device structure includes a source/drain structure over the fin. The source/drain structure is over a side of the gate structure and connected to the first nanostructure, the source/drain structure has an upper portion, a lower portion, and a neck portion between the upper portion and the lower portion, the upper portion has a first diamond-like shape, and the lower portion is wider than the neck portion.
