Tungsten Sintered Compact Sputtering Target and Tungsten Film Formed Using Said Target
A tungsten sintered compact sputtering target, wherein a molybdenum strength detected with a secondary ion mass spectrometer (D-SIMS) is equal to or less than 1/10000 of the tungsten strength. This target reduces the specific resistance of a tungsten film sputtered using the tungsten sintered compact target by reducing the molybdenum in the tungsten sintered compact sputtering target and adjusting the grain size distribution of the W powder that is used during sintering.
