    摘要: Methods for deposition of silicon carbide films on a substrate surface are provided. The methods include the use of vapor phase carbosilane precursors and may employ plasma enhanced atomic layer deposition processes. The methods may be carried out at temperatures less than 600° C., for example between about 23° C. and about 200° C. or at about 100° C. This silicon carbide layer may then be densified to remove hydrogen content. Additionally, the silicon carbide layer may be exposed to a nitrogen source to provide reactive N—H groups, which can then be used to continue film deposition using other methods. Plasma processing conditions can be used to adjust the carbon, hydrogen and/or nitrogen content of the films.

    摘要: Embodiments of the invention contemplate the formation of a high efficiency solar cell using novel methods to form the active region(s) and the metal contact structure of a solar cell device. In one embodiment, the methods include the use of various etching and patterning processes that are used to define point contacts through a blanket dielectric layer covering a surface of a solar cell substrate. The method generally includes depositing an etchant material that enables formation of a desired pattern in a dielectric layer through which electrical contacts to the solar cell device can be formed.

    摘要: Methods of curing a silicon oxide layer on a substrate are provided. The methods may include the processes of providing a semiconductor processing chamber and a substrate and forming an silicon oxide layer filling a portion of a trench on the substrate, the silicon oxide layer including carbon species as a byproduct of formation. The methods also include introducing an acidic vapor into the semiconductor processing chamber, the acidic vapor reacting with the silicon oxide layer to remove the carbon species from the silicon oxide layer. The methods may further include depositing additional silicon oxide over the cured silicon oxide to fill the trench. The methods may also include removing the acidic vapor from the semiconductor processing chamber.
