| Zusammenfassung: | A method of forming a semiconductor device includes forming a gate structure over first and second fins over a substrate; forming an interlayer dielectric layer surrounding first and second fins; etching a first trench in the interlayer dielectric layer between the first and second fins uncovered by the gate structure; forming a helmet layer lining the first trench; and forming a dielectric feature in the first trench. |
