发明名称 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.
