METHOD AND DESIGN FOR SPUTTER TARGET ATTACHMENT TO A BACKING PLATE

A method of assembling the components of a sputter cathode assembly via thermal expansion of projections provided on one assembly member to provide thermal contact to the other assembly member, and the sputter cathode formed thereby are described. The method forms a temporary mechanical attachment o...

Beschreibung
Zusammenfassung:	A method of assembling the components of a sputter cathode assembly via thermal expansion of projections provided on one assembly member to provide thermal contact to the other assembly member, and the sputter cathode formed thereby are described. The method forms a temporary mechanical attachment of component members that ends when the components are cooled below the predetermined contact temperature. The method optionally includes mechanically interlocking the assembly components together.
