Abstract:
Semiconductor devices and methods of fabricating semiconductor devices are provided. The present disclosure provides a semiconductor device that includes a first fin structure and a second fin structure each extending from a substrate; a first gate segment over the first fin structure and a second gate segment over the second fin structure; first isolation feature separating the first and second gate segments; a first source/drain (S/D) feature over the first fin structure and adjacent to the first gate segment; a second S/D feature over the second fin structure and adjacent to the second gate segment; and a second isolation feature also disposed in the trench. The first and second S/D features are separated by the second isolation feature, and a composition of the second isolation feature is different from a composition of the first isolation feature.

Claim (Index 8):
A method of fabricating a semiconductor device, comprising:\n providing a structure, the structure comprising:\n a substrate; \n a first fin structure and a second fin structure each extending from the substrate; \n a first gate segment over the first fin structure and a second gate segment over the second fin structure, the first and second gate segments extending along a first direction; \n a first source/drain (S/D) feature over the first fin structure and adjacent to the first gate segment; \n a second S/D feature over the second fin structure and adjacent to the second gate segment; \n an oxygen-containing dielectric layer over the first and second S/D features; and \n a trench extending along a second direction between the first and second gate segments and within the oxygen-containing dielectric layer, the trench separating the first and second gate segments, the second direction being generally perpendicular to the first direction, wherein the trench exposes a sidewall of the first gate segment, a sidewall of the second gate segment, and sidewalls of the oxygen-containing dielectric layer; \n treating the exposed sidewall of the first gate segment, the exposed sidewall of the second gate segment, and the exposed sidewalls of the oxygen-containing dielectric layer with Ar plasma and a hydrogen-containing reagent, resulting in hydroxyl groups on treated sidewalls of the oxygen-containing dielectric layer; soaking the treated sidewall of the first gate segment, the treated sidewall of the second gate segment, and the treated sidewalls of the oxygen-containing dielectric layer with an inhibitor bondable to hydroxyl groups, resulting in the inhibitor bonded to the sidewalls of the oxygen-containing dielectric layer; and after the soaking, depositing a first dielectric layer over the trench, wherein the first dielectric layer is formed on surfaces free of the inhibitor.
