Abstract:
In various embodiments, tubular sputtering targets comprising molybdenum are provided and sputtered to produce thin films comprising molybdenum. The sputtering targets may be formed by forming a tubular billet having an inner diameter IDI and an outer diameter ODI, the formation comprising pressing molybdenum powder in a mold and sintering the pressed molybdenum powder, working the tubular billet to form a worked billet having an outer diameter ODf smaller than ODI, and heat treating the worked billet. The sputtering targets may have a substantially uniform texture of (a) a 110 orientation parallel to a longitudinal direction and (b) a 111 orientation parallel to a radial direction.
