    摘要: The present disclosure provides a method for fabricating an integrated circuit. The method includes forming an energy removable film (ERF) on a substrate; forming a first dielectric layer on the ERF; patterning the ERF and first dielectric layer to form a trench in the ERF and the first dielectric layer; filling a conductive material in the trench; forming a ceiling layer on the first dielectric layer and conductive material filled in the trench; and applying energy to the ERF to form air gaps in the ERF after the forming of the ceiling layer.

    摘要: A method of forming a semiconductor structure includes providing a substrate; forming a low-k dielectric layer over the substrate; embedding a conductive wiring into the low-k dielectric layer; and thermal soaking the conductive wiring in a carbon-containing silane-based chemical to form a barrier layer on the conductive wiring. A lining barrier layer is formed in the opening for embedding the conductive wiring. The lining barrier layer may comprise same materials as the barrier layer, and the lining barrier layer may be recessed before forming the barrier layer and may contain a metal that can be silicided.
