  • Patent number: 9926623
    Abstract: In various embodiments, sputtering targets are formed by introducing molybdenum powder into a sheet bar mold, pressing the powder to form a sheet bar, sintering the sheet bar to form an ingot having a density of at least 90% of a theoretical density, preheating the ingot, rolling the ingot to form a plate, and heat treating the plate.
    Type: Grant
    Filed: March 4, 2016
    Date of Patent: March 27, 2018
    Assignee: H.C. STARCK INC.

  • 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.

  • 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.
