Abstract

A semiconductor device structure, along with methods of forming such, are described. The structure includes a first source/drain epitaxial feature, a second source/drain epitaxial feature disposed adjacent the first source/drain epitaxial feature, a first dielectric layer disposed between the first source/drain epitaxial feature and the second source/drain epitaxial feature, a first dielectric spacer disposed under the first dielectric layer, and a second dielectric layer disposed under the first dielectric layer and in contact with the first dielectric spacer. The second dielectric layer and the first dielectric spacer include different materials.
