  • Patent number: 11753702
    Abstract: The invention is directed at sputter targets including 50 atomic % or more molybdenum, a second metal element of niobium or vanadium, and a third metal element selected from the group consisting of titanium, chromium, niobium, vanadium, and tantalum, wherein the third metal element is different from the second metal element, and deposited films prepared by the sputter targets. In a preferred aspect of the invention, the sputter target includes a phase that is rich in molybdenum, a phase that is rich in the second metal element, and a phase that is rich in the third metal element.

  • Publication number: 20220220603
    Abstract: Sputtering targets including molybdenum, niobium and tantalum are found to be useful for sputtering films for electronic devices. Sputtering targets with about 88 to 97 weight percent molybdenum show improved performance, particularly with respect to etching, such as when simultaneously etching an alloy layer including the Mo, Nb, and Ta, and a metal layer (e.g., an aluminum layer). The targets are particularly useful in manufacturing touch screen devices.

  • Patent number: 11328912
    Abstract: A sputtering target that includes at least two consolidated blocks, each block including an alloy including molybdenum in an amount greater than about 30 percent by weight and at least one additional alloying ingredient; and a joint between the at least two consolidated blocks, the joint being free of any microstructure due to an added bonding agent (e.g., powder, foil or otherwise), and being essentially free of any visible joint line the target that is greater than about 200 ?m width (e.g., less than about 50 ?m width). A process for making the target includes hot isostatically pressing, below a temperature of 1080° C., consolidated perform blocks that may be surface prepared (e.g., roughened to a predetermined roughness value) prior to pressing.

  • Patent number: 10643827
    Abstract: A sputtering target that includes at least two consolidated blocks, each block including an alloy including a first metal (e.g., a refractory metal such as molybdenum in an amount greater than about 30 percent by weight) and at least one additional alloying ingredient; and a joint between the at least two consolidated blocks, the joint being prepared free of any microstructure derived from a diffusion bond of an added loose powder. A process for making the target includes hot isostatically pressing (e.g., below a temperature of 1080° C.), consolidated preform blocks that, prior to pressing, have interposed between the consolidated powder metal blocks at least one continuous solid interface portion. The at least one continuous solid interface portion may include a cold spray body, which may be a mass of cold spray deposited powders on a surface a block, a sintered preform, a compacted powder body (e.g., a tile), or any combination thereof.
