  • Publication number: 20090010792
    Abstract: A method of fabricating a sputtering target assembly comprises steps of mixing/blending selected amounts of powders of at least one noble or near-noble Group VIII metal at least one Group IVB, VB, or VIB refractory metal; forming the mixed/blended powder into a green compact having increased density; forming a full density compact from the green compact; cutting a target plate slice from the full density compact; diffusion bonding a backing plate to a surface of the target plate slice to form a target/backing plate assembly; and machining the target/backing plate assembly to a selected final dimension. The disclosed method is particularly useful for fabricating large diameter Ru—Ta alloy targets utilized in semiconductor metallization processing.

  • Publication number: 20050236270
    Abstract: A method for manufacturing a sputter target in which cooling rates are selectively controlled, by generating a sputter surface and a backside surface obverse to the sputter surface. The backside surface includes at least a first textured region. The first textured region aids in cooling a region of the sputter target adjacent to the first textured region, by effectuating heat dissipation.

  • Publication number: 20030228238
    Abstract: A target for a deposition apparatus is formed by blending at least two different types of powders together and consolidating the powders with a powder metallurgy process to form a billet. The target is then formed from the billet. The target includes a first material phase having a first PTF and a second material phase having a second PTF higher than the first PTF. The second PTF is also higher than a PTF of a material having the same chemistry as the target.

  • Patent number: 6599377
    Abstract: An ingot of material which is normally too brittle to allow successful rolling and wrought processing is formed so as to have a thickness-to-width ratio of less than about 0.5 and is annealed in a temperature range of 1000° F. to 2500° F. for a preselected time. The ingot is then rolled in a temperature range of 1500° F. to 2500° F. Additional/optional annealing of the resulting rolled plate in a temperature range of 500° F. to 2000° F., or between room temperature and 1500° F., and/or a final annealing between 500° F. and 1500° F., is possible. Sputtering targets are cut out of the rolled plate and used for the manufacture of storage disks.
