Abstract
A semiconductor device structure is provided. The semiconductor device structure includes a gate stack over a semiconductor substrate and a source/drain structure adjacent to the gate stack. The semiconductor device structure also includes a cap element over the source/drain structure. The cap element has a first top plane, and the source/drain structure has a second top plane. The first top plane of the cap element is wider than the second top plane of the source/drain structure. A surface orientation of the first top plane of the cap element and a surface orientation of a side surface of the cap element are different from each other. The surface orientation of the first top plane of the cap element is {311}.
