    摘要: Embodiments of the present invention generally relate to methods of forming a microcrystalline silicon layer on a substrate in a deposition chamber. In, one embodiment, the method includes flowing a processing gas into a diffuser region between a backing plate and a showerhead of the deposition chamber, flowing the processing gas through a plurality of holes in the showerhead and into a process volume between the showerhead and a substrate support in the deposition chamber, igniting a plasma in the process volume, back-flowing gas ions formed in the plasma through the plurality of holes in the showerhead and into the diffuser region, mixing the gas ions and the processing gas in the diffuser region, re-flowing the gas ions and processing gas through the plurality of holes in the showerhead and into the process volume, and depositing a microcrystalline silicon layer on the substrate.

    摘要: Methods for sputter depositing a transparent conductive oxide (TCO) layer are provided in the present invention. The transparent conductive oxide layer may be utilized as a back reflector in a photovoltaic device. In one embodiment, the method includes providing a substrate in a processing chamber, forming a first portion of a transparent conductive oxide layer on the substrate by a first sputter deposition step, and forming a second portion of the transparent conductive oxide layer by a second sputter deposition step.
