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.

Abstract: A method of forming and controlling air gaps between adjacent raised features on a substrate includes forming a silicon-containing film in a bottom region between the adjacent raised features using a flowable deposition process. The method also includes forming carbon-containing material on top of the silicon-containing film and forming a second film over the carbon-containing material using a flowable deposition process. The second film fills an upper region between the adjacent raised features. The method also includes curing the materials at an elevated temperature for a period of time to form the air gaps between the adjacent raised features. The thickness and number layers of films can be used to control the thickness, vertical position and number of air gaps.

Abstract: A method of forming a dielectric layer is described. The method deposits a silicon-containing film by chemical vapor deposition using a local plasma. The silicon-containing film is flowable during deposition at low substrate temperature. A silicon precursor (e.g. a silylamine, higher order silane or halogenated silane) is delivered to the substrate processing region and excited in a local plasma. A second plasma vapor or gas is combined with the silicon precursor in the substrate processing region and may include ammonia, nitrogen (N2), argon, hydrogen (H2) and/or oxygen (O2). The equipment configurations disclosed herein in combination with these vapor/gas combinations have been found to result in flowable deposition at substrate temperatures below or about 200° C. when a local plasma is excited using relatively low power.
