    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.
