Methods of forming molybdenum sputtering targets |
摘要 |
In various embodiments, planar sputtering targets are produced by forming a billet at least by pressing molybdenum powder in a mold and sintering the pressed powder, working the billet to form a worked billet, heat treating the worked billet, working the worked billet to form a final billet, and heat treating the final billet. |

1. A method of making a planar sputtering target comprising:
forming a billet having a diameter D0, the formation comprising pressing molybdenum powder in a mold and sintering the pressed powder; working the billet to form a worked billet having a diameter D2 smaller than D0; heat treating the worked billet; working the worked billet to form a final billet having a diameter Df larger than D2; and heat treating the final billet. |
