Abstract
A FinFET device structure is provided. The FinFET device structure includes a fin structure formed over a substrate, and a gate structure formed over the fin structure. The FinFET device structure includes a source/drain (S/D) structure formed over the fin structure and adjacent to the gate structure, and an S/D contact structure formed over the S/D structure and adjacent to the gate structure. The FinFET device structure also includes a protection layer formed on the S/D contact structure, and the protection layer and the S/D contact structure are made of different materials. The protection layer has a bottommost surface in direct contact with a topmost surface of the S/D contact structure.
