Method of forming low-k films with reduced dielectric constant, reduced CHx content, and increased hardness are described. A siloxane film is on a substrate surface using a siloxane precursor comprising O—Si—O bonds and cured using ultraviolet light.

A method of fabricating air gaps in advanced semiconductor devices for low capacitance interconnects. The method includes exposing a substrate to a gas pulse sequence to deposit a material that forms an air gap between raised features.

Systems and methods for reducing obstructions in an exhaust line of a sub-atmospheric chemical vapor deposition (SACVD) system are disclosed. Such obstruction may occur due to the reaction of a silicon precursor with ozone, which forms solid particles in the exhaust line. A catalytic apparatus is provided which catalyzes the decomposition of ozone (O.sub.3) to oxygen (O.sub.2). Due to the lower reactivity of O.sub.2, the formation of solid particles is reduced.

Methods for selective deposition of silicon oxide films on metal or metallic surfaces relative to dielectric surfaces are provided. A dielectric surface of a substrate may be selectively passivated relative to a metal or metallic surface, such as by exposing the substrate to a silylating agent. Silicon oxide is then selectively deposited on the metal or metallic surface relative to the passivated oxide surface by contacting the metal surface with a metal catalyst and a silicon precursor comprising a silanol.

A doped or undoped silicon carbide film can be deposited using a remote plasma chemical vapor deposition (CVD) technique. One or more silicon-containing precursors are provided to a reaction chamber. Radical species, such as hydrogen radical species, are provided in a substantially low energy state or ground state and interact with the one or more silicon-containing precursors to deposit the silicon carbide film. A co-reactant may be flowed with the one or more silicon-containing precursors, where the co-reactant can be a depositing additive or a non-depositing additive to increase step coverage of the silicon carbide film.
