Abstract:
A semiconductor device includes a substrate having a channel region; a gate stack over the channel region; a seal spacer covering a sidewall of the gate stack, the seal spacer including silicon nitride; a gate spacer covering a sidewall of the seal spacer, the gate spacer including silicon oxide, the gate spacer having a first vertical portion and a first horizontal portion; and a first dielectric layer covering a sidewall of the gate spacer, the first dielectric layer including silicon nitride.

Claim (Index 1):
A semiconductor device, comprising:\n a substrate having a channel region, the substrate further including a source/drain (S/D) region, the S/D region having a first doped S/D region adjacent to the channel region and a second doped S/D region adjacent to the first doped S/D region, wherein the second doped S/D region is more heavily doped than the first doped S/D region; a gate stack over the channel region; a seal spacer covering a sidewall of the gate stack, the seal spacer including silicon nitride; a gate spacer covering a sidewall of the seal spacer, the gate spacer including silicon oxide, the gate spacer having a first vertical portion and a first horizontal portion, the first vertical portion offset from the second doped S/D region and in physical contact with the first doped S/D region, the first horizontal portion in physical contact with both the first doped S/D region and the second doped S/D region; and a first dielectric layer covering a sidewall of the gate spacer, the first dielectric layer including silicon nitride.
