  • Patent number: 9263623
    Abstract: Methods are described for depositing thin films, such as those used in forming a photovoltaic cell or device. In particular embodiments, one or more layers are deposited on a substrate by plasma spraying over the substrate. A grain size of grains in each of the one or more layers is at least approximately two times greater than a thickness of the respective layer. Accordingly, large flat-grained structures are formed in each respective layer, and grain boundaries within each respective layer can be minimized.

  • Publication number: 20030228238
    Abstract: A target for a deposition apparatus is formed by blending at least two different types of powders together and consolidating the powders with a powder metallurgy process to form a billet. The target is then formed from the billet. The target includes a first material phase having a first PTF and a second material phase having a second PTF higher than the first PTF. The second PTF is also higher than a PTF of a material having the same chemistry as the target.

  • Patent number: 6599377
    Abstract: An ingot of material which is normally too brittle to allow successful rolling and wrought processing is formed so as to have a thickness-to-width ratio of less than about 0.5 and is annealed in a temperature range of 1000° F. to 2500° F. for a preselected time. The ingot is then rolled in a temperature range of 1500° F. to 2500° F. Additional/optional annealing of the resulting rolled plate in a temperature range of 500° F. to 2000° F., or between room temperature and 1500° F., and/or a final annealing between 500° F. and 1500° F., is possible. Sputtering targets are cut out of the rolled plate and used for the manufacture of storage disks.
