ABSTRACT:
A sputtering target producing few particles, a backing plate or a sputtering apparatus, and a sputtering method producing few particles. An arc-spraying coating film and a plasma-spraying coating film over the former are formed on the sputtering target, a backing plate, or another surface in the sputtering apparatus, where an unwanted film might be formed. Thus a deposit is prevent from separating/flying from the target, backing plate, or another surface where an unwanted film might be formed in the sputtering apparatus.
