  • Patent number: 9334562
    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: 9309591
    Abstract: In various embodiments, tubular sputtering targets comprising molybdenum are provided and sputtered to produce thin films comprising molybdenum. The sputtering targets may be formed by forming a tubular billet having an inner diameter IDI and an outer diameter ODI, the formation comprising pressing molybdenum powder in a mold and sintering the pressed molybdenum powder, working the tubular billet to form a worked billet having an outer diameter ODf smaller than ODI, and heat treating the worked billet. The sputtering targets may have a substantially uniform texture of (a) a 110 orientation parallel to a longitudinal direction and (b) a 111 orientation parallel to a radial direction.
