  • Publication number: 20160203960
    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.

  • Publication number: 20160196961
    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.

  • Publication number: 20160196962
    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.

  • Publication number: 20150332903
    Abstract: The invention is directed at sputter targets including 50 atomic % or more molybdenum, a second metal element of titanium, and a third metal element of chromium or tantalum, 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 titanium, and a phase that is rich in the third metal element.

  • Patent number: 9150955
    Abstract: The invention relates to sputter targets and methods for depositing a layer from a sputter target. The method preferably includes the steps of; placing a sputter target in a vacuum chamber; placing a substrate having a substrate surface in the vacuum chamber; reducing the pressure in the vacuum chamber to about 100 Torr or less; removing atoms from the surface of the sputter target white the sputter target is in the vacuum chamber (e.g., using a magnetic field and/or an electric field). The deposited layer preferably includes a molybdenum containing alloy including about 50 atomic percent or more molybdenum, 0.1 to 45 atomic percent titanium; and 0.1 to 40 atomic percent of a third metal element that is tantalum or chromium.

The method preferably includes the steps of: placing a sputter target in a vacuum chamber; placing a substrate having a substrate surface in the vacuum chamber; reducing the pressure in the vacuum chamber to about 100 Torr or less; removing atoms from the surface of the sputter target while the sputter target is in the vacuum chamber (e.g., using a magnetic field and/or an electric field). The deposited layer preferably is a molybdenum containing alloy including about 50 atomic percent or more molybdenum, 0.5 to 45 atomic percent of a second metal element selected from the group consisting of niobium and vanadium; and 0.5 to 45 atomic percent of a third metal element selected from the group consisting of tantalum, chromium, vanadium, niobium, and titanium.
