  • Publication number: 20180163317
    Abstract: In one implementation, a method of depositing a material on a substrate is provided. The method comprises positioning an aluminum-containing substrate in an electroplating solution, the electroplating solution comprising a non-aqueous solvent and a deposition precursor.

  • Publication number: 20120000773
    Abstract: The present invention generally comprises one or more cooled anodes shadowing one or more gas introduction tubes where both the cooled anodes and the gas introduction tubes span a processing space defined between one or more sputtering targets and one or more substrates within a sputtering chamber. The gas introduction tubes may have gas outlets that direct the gas introduced away from the one or more substrates. The gas introduction tubes may introduce reactive gas, such as oxygen, into the sputtering chamber for depositing TCO films by reactive sputtering. During a multiple step sputtering process, the gas flows (i.e., the amount of gas and the type of gas), the spacing between the target and the substrate, and the DC power may be changed to achieve a desired result.

  • Publication number: 20090029502
    Abstract: Embodiments of the invention generally provide apparatuses and methods of substrate temperature control during thin film solar manufacturing. In one embodiment a method for forming a thin film solar cell over a substrate is provided. The method comprises performing a temperature stabilization process on a substrate to pre-heat the substrate for a substrate stabilization time period in a first chamber, calculating a wait time period for a second chamber, wherein the wait time period is bases on the availability of the second chamber, the availability of a vacuum transfer robot adapted to transfer the substrate from the first chamber to the second chamber, or a combination of both the availability of the second chamber and the availability of the vacuum transfer robot, and adjusting the temperature stabilization time period to compensate for the loss of heat from the substrate during the wait time period.
