Abstract
Provided is a sputtering target/backing plate assembly having a structure such that pure copper is embedded in a backing plate position at the central portion of the target, within sputtering target/copper-zinc alloy backing plate bonded bodies. Consequently, provided is a simple structure of sputtering target/backing plate capable of sufficiently accommodating further high-power sputtering without deteriorating the characteristics of a copper-zinc alloy backing plate that is inexpensive and excels in strength and anti-eddy current characteristics.
