Abstract:
Methods are described for forming a flowable low-k dielectric film on a patterned substrate. The film may be a silicon-carbon-oxygen (Si-C-O) layer in which the silicon and carbon constituents come from a silicon and carbon containing precursor while the oxygen may come from an oxygen-containing precursor activated in a remote plasma region. Shortly after deposition, the silicon-carbon-oxygen layer is treated by exposure to a hydrogen-and-nitrogen-containing precursor such as ammonia prior to curing. The treatment may remove residual moisture from the silicon-carbon-oxygen layer and may make the lattice more resilient during curing and subsequent processing. The treatment may reduce shrinkage of the silicon-carbon-oxygen layer during subsequent processing.

Methods for forming a passivation protection structure on a metal line layer formed in an insulating material in an interconnection structure are provided. In one embodiment, a method for forming passivation protection on a metal line in an interconnection structure for semiconductor devices includes selectively forming a metal capping layer on a metal line bounded by a dielectric bulk insulating layer in an interconnection structure formed on a substrate in a processing chamber incorporated in a multi-chamber processing system, in-situ forming a barrier layer on the substrate in the processing chamber; wherein the barrier layer is a metal dielectric layer, and forming a dielectric capping layer on the barrier layer in the multi-chamber processing system.

A low k porous dielectric film with improved mechanical strength and methods for making the same are disclosed herein. A method of forming a dielectric layer can include positioning a substrate in a processing chamber, delivering a deposition gas to the processing chamber, depositing a dense organosilicon layer using the deposition gas on the surface of the substrate, the dense organosilicon layer comprising a porogenic carbon, forming a pore-forming plasma from a reactant gas, exposing the dense organosilicon layer to the pore-forming plasma to create a porous organosilicon layer, wherein the pore-forming plasma removes at least a portion of the porogenic carbon and exposing the porous organosilicon layer to ultraviolet (UV) radiation.

Abstract:
Provided are methods of for deposition of various silicon-containing films using disiloxane or disiloxane derivative. Certain methods relate to deposition of Si x O y using an oxygen-containing compound, plasma or halosilane. Certain other methods relate to deposition of metal oxides using a metal halide and disiloxane. Yet other methods pertain to deposition of SiOC films using disiloxane or carbon-containing disiloxane derivatives, possibly with organic hydroxides.

Abstract:
Methods of patterning low-k dielectric films are described. In an example, a method of patterning a low-k dielectric film involves forming and patterning a mask layer above a low-k dielectric layer, the low-k dielectric layer disposed above a substrate. The method also involves modifying exposed portions of the low-k dielectric layer with a nitrogen-free plasma process. The method also involves removing, with a remote plasma process, the modified portions of the low-k dielectric layer selective to the mask layer and unmodified portions of the low-k dielectric layer.
