An exemplary contact gate isolation process may include recessing (e.g., by etching) sidewall portions of a high-k gate dielectric and gate spacers of a gate structure to form a contact gate isolation (CGI) opening that exposes sidewalls of a gate electrode of the gate structure, forming a gate isolation liner along the sidewalls of the gate electrode that partially fills the CGI opening, and forming a gate isolation layer over the gate isolation liner that fills a remainder of the CGI opening. A dielectric constant of the gate isolation liner is less than a dielectric constant of the high-k gate dielectric. A dielectric constant of the gate isolation layer is less than a dielectric constant of the high-k gate dielectric. A dielectric constant of the gate isolation layer may be less than a dielectric constant of the gate isolation layer.
