Abstract:
A semiconductor device includes an active fin on a substrate, a gate structure on the active fin, a gate spacer structure on a sidewall of the gate structure, and a source/drain layer on at least a portion of the active fin adjacent the gate spacer structure. The gate spacer structure includes a wet etch stop pattern, an oxygen-containing silicon pattern, and an outgas sing prevention pattern sequentially stacked.

Claim (Index 14):
A method of manufacturing a semiconductor device, the method comprising:\n forming an isolation pattern on a substrate to define first and second active fins on first and second regions, respectively, of the substrate; forming first and second dummy gate structures on the first and second active fins, respectively; forming a first gate spacer structure on a sidewall of the first dummy gate structure, the first dummy gate spacer structure including a first wet etch stop pattern, a first oxygen-containing silicon pattern, and a first outgas sing prevention pattern sequentially stacked; performing a first selective epitaxial growth (SEG) process to form a first source/drain layer on at least a portion of the first active fin adjacent the first gate spacer structure; forming a second gate spacer structure on a sidewall of the second dummy gate structure, the second dummy gate spacer structure including a second wet etch stop pattern, a second oxygen-containing silicon pattern, and a second outgas sing prevention patternsequentially stacked; performing a second selective epitaxial growth (SEG) process to form a second source/drain layer on at least a portion of the second active fin adjacent the second gate spacer structure; and replacing the first and second dummy gate structures with first and second gate structures, respectively.
