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 9):
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, the first gate spacers including an upper portion having a first thickness and a bottom portion below the upper portion and extending away from the first gate stack structure, wherein the bottom portion is contiguous with the upper portion and includes a continuously increasing thickness from the first thickness to point level with a bottom of a gate dielectric layer over the first gate stack structure; second gate spacers formed on sidewalls of the second gate stack structure; a first epitaxial structure formed adjacent to the first gate stack structure, wherein the bottom portion is in direct contact with the first epitaxial structure; and a second epitaxial structure formed adjacent to the second gate stack structure.
