Among other things, one or more techniques for forming a low k dielectric around a metal line during an integrated circuit (IC) fabrication process are provided. In an embodiment, a metal line is formed prior to forming a surrounding low k dielectric layer around the metal line. In an embodiment, the metal line is formed by filling a trench space in a skeleton layer with metal. In this embodiment, the skeleton layer is removed to form a dielectric space in a different location than the trench space. The dielectric space is then filled with a low k dielectric material to form a surrounding low k dielectric layer around the metal line. In this manner, damage to the surrounding low k dielectric layer, that would otherwise occur if the surrounding low k dielectric layer was etched, for example, is mitigated. |
