  • Patent number: 8703233
    Abstract: In various embodiments, a joined sputtering target is formed by filling at least a portion of a gap between two discrete sputtering-target tiles with a gap-fill material, spray-depositing a spray material to form a partial joint, removing at least a portion of the gap-fill material, and, thereafter, spray-depositing the spray material to join the tiles.

  • Patent number: 8088232
    Abstract: Molybdenum, sputtering targets and sintering characterized as having no or minimal texture banding or through thickness gradient. The molybdenum sputtering targets having a fine, uniform grain size as well as uniform texture, are high purity and can be micro-alloyed to improved performance. The sputtering targets can be round discs, square, rectangular or tubular and can be sputtered to form thin films on substrates. By using a segment-forming method, the size of the sputtering target can be up to 6 m×5.5 m. The thin films can be used in electronic components such as Thin Film Transistor-Liquid Crystal Displays, Plasma Display Panels, Organic Light Emitting Diodes, Inorganic Light Emitting Diode Displays, Field Emitting Displays, solar cells, sensors, semiconductor devices, and gate device for CMOS (complementary metal oxide semiconductor) with tunable work functions.

  • Publication number: 20110097236
    Abstract: Molybdenum titanium sputter targets are provided. In one aspect, the targets are substantially free of the ?(Ti, Mo) alloy phase. In another aspect, the targets are substantially comprised of single phase ?(Ti, Mo) alloy. In both aspects, particulate emission during sputtering is reduced. Methods of preparing the targets, methods of bonding targets together to produce large area sputter targets, and films produced by the targets, are also provided.
