    摘要: A method of forming and removing a sacrificial oxide layer is described. The method includes forming a step on a substrate, where the step has a top and sidewalls. The method may also include forming the sacrificial oxide layer around the step by chemical vapor deposition of molecular oxygen and TEOS, where the oxide layer is formed on the top and sidewalls of the step. The method may also include removing a top portion of the oxide layer and the step; removing a portion of the substrate exposed by the removal of the step to form a etched substrate; and removing the entire sacrificial oxide layer from the etched substrate.

    摘要: Embodiments of the present invention generally provide a method for forming a plurality of thin film single or multi-junction solar cell in a substrate processing chamber. In one embodiment, a method for processing a plurality of thin film solar cell substrates includes depositing sequentially a first undoped layer and a first doped layer over a surface of a first substrate and a chamber component in a single processing chamber, removing the substrate having the doped and undoped layers from the processing chamber, removing the second doped layer deposited on the chamber component to expose underlying first undoped layer which serves as a seasoning layer for a second substrate to be processed in the processing chamber, and depositing sequentially a second undoped layer and a second doped layer on the second substrate in the processing chamber. In one example, the first undoped layer is amorphous silicon or microcrystalline silicon. A full cleaning process may be performed at desired intervals to expose the surfaces of the chamber component before a regular seasoning process and the subsequent depositions are proceeded in the processing chamber.
