Al-Ni-La system Al-based alloy sputtering target

摘要

The invention relates to an Al—Ni—La system Al-based alloy sputtering target where a total area of an Al—Ni system intermetallic compound having an average particle diameter of 0.3 μm to 3 μm with respect to a total area of the entire Al—Ni system intermetallic compound is 70% or more in terms of an area fraction, and a total area of an Al—La system intermetallic compound having an average particle diameter of 0.2 μm to 2 μm with respect to a total area of the entire Al—La system intermetallic compound is 70% or more in terms of an area fraction.
