    摘要： A method for providing a dielectric film having a low dielectric constant. The deposited film is particularly useful as an intermetal or premetal dielectric layer in an integrated circuit. The low dielectric constant film is a carbon-doped silicon oxide layer deposited from a thermal, as opposed to plasma, CVD process. The layer is deposited from a process gas of ozone and an organosilane precursor having at least one silicon-carbon (Si—C) bond. During the deposition process the wafer is heated to a temperature less than 250° C. and preferably to a temperature between 100-200° C. Enhancements to the process include adding Boron and/or Phosphorus dopants, two step deposition, and capping the post cured layer.

    摘要： An embodiment of the present invention provides methods for forming a carbon-containing layer having a low dielectric constant and good gap-fill capabilities. A method includes depositing a carbon-containing layer on a substrate and transforming the carbon-containing layer to remove at least some of the carbon. The transforming step may include annealing the carbon-containing layer in a furnace containing a hydrogen atmosphere, for example. The carbon-containing layer may be a carbon-doped silicon oxide material, where the transforming step changes the carbon-doped silicon oxide. Additionally, the method may include subjecting the annealed layer to a hydrogen and/or low oxygen plasma treatment to further remove carbon from the layer. Additionally, a step of adding a capping layer to the annealed, plasma treated material is provided. Products made by the above methods are also included, such as a product including a low k carbon-containing layer where the low k carbon-containing layer has been transformed to remove some of the carbon from the layer. An additional product includes a transformed carbon-containing layer further subjected to a hydrogen plasma treatment to remove more carbon from the layer. Further, a capping layer deposited over the transformed and hydrogen plasma treated layer is provided.

    摘要： A method for forming an insulation layer over a substrate. The method forms a carbon-doped silicon oxide layer by thermal chemical vapor deposition using an organosilane. The carbon-doped silicon oxide layer is subsequently cured and densified. In one embodiment, the cured film is densified in a nitrogen-containing plasma. The method is particularly suitable for deposition of low dielectric constant films, i.e., where k is less than or equal to 3.0. Low-k, carbon-doped silicon oxide methylsilane or di-, tri-, tetra-, or phenylmethylsilane. and ozone. The above method can be carried out in a substrate processing system having a process chamber; a substrate holder, a heater, a gas delivery system, and a power supply, all of which are coupled to a controller. The controller contains a memory having a computer-readable medium with a program embodied for directing operation of the system in accordance with above method.

    摘要： A method of forming an organosilicate layer is disclosed. The organosilicate layer is formed by reacting a gas mixture comprising a phenyl-based alkoxysilane compound. The gas mixture may be reacted by applying an electric field thereto. The gas mixture may optionally include an organosilane compound as well as an oxidizing gas. The organosilicate layer is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the organosilicate layer is used as an anti-reflective coating (ARC). In another integrated circuit fabrication process, the organosilicate layer is used as a hardmask. In yet another integrated circuit fabrication process, the organosilicate layer is incorporated into a damascene structure.
