Abstract: The invention encompasses a construction in which a PVD target is bonded to a backing plate. The target has a bonding surface utilized in forming the bond to the backing plate, and the backing plate has a bonding surface utilized in forming the bond to the target. One or more holes extend into the target through the target bonding surface and/or one or more holes extend into the backing through the backing plate bonding surface. The invention also includes methods of forming PVD target/backing plate constructions, and methods of utilizing holes extending into one or both of the target and the backing plate of the target/backing plate construction during ultrasound determination of a thickness of the target.
