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 1):
A semiconductor device structure, comprising:\n a first gate stack structure and a second gate stack structure formed on a substrate; first gate spacers formed on sidewalls of the first gate stack structure, wherein the first gate spacers comprise a top portion and a protruding bottom portion directly below the top portion, the top portion and the protruding bottom portion form a recessed corner at a joint of the top portion and the protruding bottom portion, the recessed corner is lower than a top of a gate dielectric layer of the first gate stack structure, and the protruding bottom portion slopes to a top surface of the substrate; and second gate spacers formed on sidewalls of the second gate stack structure, wherein the second gate spacers wherein the second gate spacers have a substantially constant thickness along a gate electrode and gate dielectric layer of the second gate stack structure.
