    摘要: 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.

    摘要: Methods and corresponding photoresists are described for fine linewidth lithography using x-rays, e-beams, visible spectrum optical lithography, ultra-violet optical lithography or extreme ultra-violet lithography. The methods include the formation of a photoresist film including a dopant having an atomic mass greater than or equal to twenty two. The dopant may be introduced daring the formation of the photoresist. The photoresist includes the dopant to increase the absorption of radiation during lithography. The photoresist may be silicon-, germanium or carbon-based photoresists.

    摘要: Embodiments of the present invention generally provide methods for forming a silicon nitride layer on a substrate. In one embodiment, a method of forming a silicon nitride layer using remote plasma chemical vapor deposition (CVD) at a temperature that is less than 300 degrees Celsius is disclosed.

    摘要: Embodiments of the present invention generally relate to methods for forming a flowable carbon-containing film on a substrate. In one embodiment, an oxygen-containing gas is flowed into a remote plasma region to produce oxygen-containing plasma effluents, and a carbon-containing gas is combined with the oxygen-containing plasma effluents in a substrate processing region which contains the substrate. A carbon-containing film is formed in trenches which are formed on the substrate and a low K dielectric material is deposited on the carbon-containing film in the trenches. The carbon-containing film is decomposed by an UV treatment and airgaps are formed in the trenches under the low K dielectric material.
