    摘要: A method of fabricating an alloy sputtering target having fine precipitates of the second phase material and small, randomly oriented and uniform grains. The new method includes solution treatment to minimize second-phase precipitate size, cryo-deformation to prevent the formation of cubic structures and recrystallization to generate fine uniform grain sizes having a random orientation.

    摘要: A method of manufacturing a sputter target is provided which comprises mixing aluminum and at least one other metallic powder to form a powder blend, compressing said powder blend under significant force to achieve a pressed blank having a packing density of at least 50% of the theoretical density, heating the blank at a temperature less then the temperature which would form greater than an average of 25% inter-metallic phases in the blank under the conditions employed, rolling the blank to obtain at least 95% of the theoretical thickness of the blank, and bonding the blank to a suitable substrate. Also provided is a sputter target made from this method.

    摘要: A single phase W-Ti sputter target and a method of manufacturing the target are disclosed. The target is produced by mixing powders of tungsten and titanium and subjecting the mixed powders to a pressing operation for a time, temperature and pressure sufficient to achieve a mutual solid solution of W and Ti, forming single .beta.(Ti,W) phase. The single phase sputtering target emits much less particulate during sputtering than conventional multiphase W-Ti targets of comparable density and composition.

    摘要: A method is provided for fabricating Cu/Cr sputter targets having a density of at least about 90% of theoretical density and an oxygen content of less than about 1000 ppm. According to the principles of the present invention, Cu and Cr powders, each having particles in the size range of about 20 &mgr;m to about 150 &mgr;m and having oxygen contents preferably less than about 1200 ppm and 600 ppm, respectively, are blended and pressed by hot pressing. A low-oxygen content, high-density Cu/Cr target is thereby achieved for the sputtering of thin films having a defect generation of about 0%.
