  • Patent number: 7378160
    Abstract: The invention has an object of obtaining a low-profile electrolytic copper foil made by electrolytic copper foil manufacturing using a cathode drum such that the surface roughness on the rough surface side (the opposite side to the lustrous surface) is low. In particular, the invention has an object of obtaining an electrolytic copper foil that can be finely patterned and have an excellent elongation and tensile strength at normal and high temperatures. This object is attained by using a copper electrolytic solution containing, as additives, an organosulfur compound, and an amine compound having a specific skeleton represented by undermentioned general formula (1) obtained by additively reacting an amine compound and a compound having one or more epoxy groups in a molecule thereof to an addition reaction.

  • Patent number: 7371467
    Abstract: A component capable of being exposed to a plasma in a process chamber has a structure having an electroplated coating comprising yttrium-containing species. The electroplated coating is resistant to corrosion in the plasma, and can have a compositional gradient of yttrium-containing species through a thickness of the coating. In one embodiment, the coating is formed by electroplating a layer comprising yttrium onto the surface, and then electroplating a second layer onto the first layer, and annealing the first and second layers. The second layer can comprise aluminum or zirconium. In another embodiment, the coating is formed by electroplating a layer comprising a mixture of aluminum and yttrium onto the surface and annealing the layer.

  • Patent number: 7371461
    Abstract: Interconnect structures possessing an organosilicate glass based material for 90 nm and beyond BEOL technologies in which a multilayer hardmask using a line-first approach are described. The interconnect structure of the invention achieves respective improved device/interconnect performance and affords a substantial dual damascene process window owing to the non-exposure of the OSG material to resist removal plasmas and because of the alternating inorganic/organic multilayer hardmask stack. The latter feature implies that for every inorganic layer that is being etched during a specific etch step, the corresponding pattern transfer layer in the field is organic and vice-versa.

  • Patent number: 7364801
    Abstract: An environmental coating suitable for use on turbine components, such as turbine disks and turbine seal elements, formed of alloys susceptible to oxidation and hot corrosion. The environmental coating is predominantly a solid solution phase of nickel, iron, and/or cobalt. The coating contains about 18 weight percent to about 60 weight percent chromium, which ensures the formation of a protective chromia (Cr2O3) scale while also exhibiting high ductility. The coating may further contain up to about 8 weight percent aluminum, as well as other optional additives. The environmental coating is preferably sufficiently thin and ductile to enable compressive stresses to be induced in the underlying substrate through shot peening without cracking the coating.

  • Patent number: 7326441
    Abstract: A coating and process for depositing the coating on a substrate. The coating is a nickel aluminide overlay coating of predominantly the beta (NiAl) and gamma-prime (Ni3Al) intermetallic phases, and is suitable for use as an environmental coating and as a bond coat for a thermal barrier coating (TBC). The coating can be formed by depositing nickel and aluminum in appropriate amounts to yield the desired beta+gamma prime phase content. Alternatively, nickel and aluminum can be deposited so that the aluminum content of the coating exceeds the appropriate amount to yield the desired beta+gamma prime phase content, after which the coating is heat treated to diffuse the excess aluminum from the coating into the substrate to yield the desired beta+gamma prime phase content.
