    摘要: A method of processing a substrate including depositing a low dielectric constant film comprising silicon, carbon, and oxygen on the substrate and depositing an oxide rich cap on the low dielectric constant film is provided. The low dielectric constant film is deposited in the presence of low frequency RF power from a gas mixture including an organosilicon compound and an oxidizing gas. The low frequency RF power is terminated after the deposition of the low dielectric constant film. The oxide rich cap is deposited on the low dielectric constant film in the absence of low frequency RF power from another gas mixture including the organosilicon compound and the oxidizing gas used to deposit the low dielectric constant film.

    摘要: Embodiments of the invention generally provide a method of forming an air gap between conductive elements of a semiconductor device, wherein the air gap has a dielectric constant of approximately 1. The air gap may generally be formed by depositing a sacrificial material between the respective conductive elements, depositing a porous layer over the conductive elements and the sacrificial material, and then stripping the sacrificial material out of the space between the respective conductive elements through the porous layer, which leaves an air gap between the respective conductive elements. The sacrificial material may be, for example, a polymerized alpha terpinene layer, the porous layer may be, for example, a porous carbon doped oxide layer, and the stripping process may utilize a UV based curing process, for example.
