Abstract:
A semiconductor device structure and method for forming the same are provided. The semiconductor device structure includes a substrate and a gate stack structure formed on the substrate. The semiconductor device structure also includes gate spacers formed on the sidewall of the gate stack structure, and the gate spacers include a top portion and a bottom portion adjoined to the top portion, and the bottom portion slopes to a top surface of the substrate. The semiconductor device structure further includes an epitaxial structure formed adjacent to the gate spacers, and the epitaxial structure is formed below the gate spacers.

Claim (Index 17):
A semiconductor device structure, comprising:\n a first gate stack structure and a second gate stack structure formed on a substrate, wherein the first gate stack structure comprises a first gate dielectric layer and a first gate electrode layer over the first gate dielectric layer; first gate spacers formed on sidewalls of the first gate stack structure, wherein the first gate spacers comprise a top portion and a bottom portion directly below the top portion, the top portion and the bottom portion form a recessed corner at a joint of the top portion and the bottom portion, and the recessed corner is lower than a top of the first gate dielectric layer; a first source/drain structure formed adjacent to the first gate stack structure; and a second source/drain structure formed adjacent to the second gate stack structure.
