  • Patent number: 10023939
    Abstract: A unique sequence of steps is provided to reduce contaminants along one or more surfaces and faces of gold evaporative sources without deleteriously impacting the structure of the gold evaporative sources. Edges are deburred; contaminants are successfully removed therealong; and surface smoothness is substantially retained. The resultant gold evaporative source is suitable for use in evaporative processes as a precursor to gold film deposition without the occurrence or a substantial reduction in the likelihood of spitting by virtue of significantly reduced levels of contaminants, in comparison to gold evaporative sources subject to a standard cleaning protocol.

  • Publication number: 20130140173
    Abstract: This invention utilizes a co-extrusion or co-drawing process to directly bond a tubular target to an inner backing tube. The co-extrusion or co-drawing process reduces the inner and outer diameters of the outer tubular target to cause portions of the target to protrude and at least partially fill into grooves along the inner backing tube. The filling causes the target to interlock to the backing plate.

  • Patent number: 8123107
    Abstract: The method forms a sputter target assembly by attaching a sputter target to an insert and applying a bond metal layer between the insert and a backing plate. Then pressing the insert and backing plate together forms a solid state bond with the bond metal layer, attaches the insert to the backing plate and forms at least one cooling channel between the insert and the backing plate.

  • Patent number: 7320736
    Abstract: The high-purity aluminum sputter target is at least 99.999 weight percent aluminum and has a grain structure. The grain structure is at least 99 percent recrystallized and has a grain size of less than 200 ?m. The method forms high-purity aluminum sputter targets by first cooling a high-purity target blank to a temperature of less than ?50 ° C. and then deforming the cooled high-purity target blank introduces intense strain into the high-purity target. After deforming, recrystallizing the grains at a temperature below 200 ° C. forms a target blank having at least 99 percent recrystallized grains. Finally, finishing at a low temperature sufficient to maintain the fine grain size of the high-purity target blank forms a finished sputter target.
