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 18):
A method, comprising:\n forming a gate structure on a substrate; forming a seal spacer covering the gate structure and a portion of the substrate; removing a portion of the seal spacer to expose the portion of the substrate; forming a gate spacer covering the seal spacer and directly on the exposed portion of the substrate, the gate spacer having a first vertical portion and a first horizontal portion; forming a hard mask layer covering the gate spacer, the hard mask layer having a second vertical portion and a second horizontal portion; removing the second horizontal portion of the hard mask layer and part of the first horizontal portion of the gate spacer that is under the second horizontal portion of the hard mask layer; and forming a contact etch stop (CES) layer covering the gate spacer.
