Beschreibung
Zusammenfassung:	A sputtering target assembly includes a sputtering target having a rear surface, a backing plate having a front surface, and an interlayer disposed between the target and the backing plate. The interlayer includes a first interlayer portion disposed proximate the target material rear surface, and a second interlayer portion disposed proximate the backing plate front surface. The first interlayer portion is formed of a first mixture containing a first material and a second material and having a higher concentration of the first material than the second material, and the second interlayer portion is formed of a second mixture containing the first material and the second material and having a higher concentration of the second material than the first material. A method of making is also provided.
