    摘要: A UV radiation source is tunable to optimize the process of densifying a carbon-doped silicon oxide film. The composition and relative concentration of stimulated gases stimulated within an airtight bulb is controlled to produce radiation optimized for absorption by undesirable chemical bonds of the carbon-doped silicon oxide film, leading to disruption of these bonds and their replacement by more desirable stable chemical bonds. The energy of radiation emitted by the source is determined by the identity of excited chemical species, and the intensity of the radiation emitted by the source is determined by the concentration of the excited chemical species. By exciting a specific mixture of gases, radiation is emitted at a combination of energies and intensities calculated to disrupt populations of unstable bonds in the carbon-doped silicon oxide film while leaving desirable bonds in the film unaffected.

    摘要: A method of minimizing particle or residue accumulation within an exhaust line of a substrate processing chamber having a downstream plasma apparatus connected to the exhaust line. One embodiment of the method turns ON the downstream plasma apparatus during a substrate deposition step and a chamber clean operation, and switches the downstream plasma apparatus OFF at other times including the time during which purge gases are flowed into the chamber and various chamber set up or conditioning steps are performed. The method includes depositing a film over a substrate disposed in the substrate processing chamber by (i) flowing a deposition gas into the substrate processing chamber, exhausting at least some of the deposition gas from the processing chamber through an exhaust line and into the downstream plasma apparatus, and forming a plasma within the downstream plasma apparatus; and then (ii) stopping the flow of the deposition gas, turning the plasma OFF, and flowing a purge gas into the substrate processing chamber. After one or more film deposition steps, the chamber is cleaned to remove film deposition from the interior surfaces of the chamber by (i) flowing an etchant into the substrate processing chamber, exhausting the etchant from the substrate processing chamber through an exhaust line and into the downstream plasma apparatus, and forming a plasma within the downstream plasma apparatus; and then (ii) stopping the flow of the etchant, turning the plasma OFF, and flowing a purge gas into the substrate processing chamber.

    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.
