Abstract

Provided is a sputtering target-backing plate assembly wherein a Cu—Cr alloy backing plate is bonded to a Ti target via a layer of a strain absorbing material placed at an interface between the Ti target and the Cu—Cr alloy backing plate. In particular, the present invention relates to a sputtering target-backing plate assembly and a production method thereof, the assembly being capable of absorbing strain at the interface between the target and the backing plate in order to prevent deformation (displacement) during sputtering. An object of the present invention is to solve a problem inherent to Titanium (Ti) and a problem in selecting a backing plate compatible with it.
