Abstract:
1. A method of forming a joined sputtering target comprising a sputtering material, the method comprising: forming a mechanical joint between two discrete sputtering-target tiles by (i) overlapping or (ii) overlapping and interlocking the tiles at an interface therebetween, the interface comprising a recess over the mechanical joint, and each of the tiles consisting essentially of the sputtering material; after (i) overlapping or (ii) overlapping and interlocking the tiles at the interface therebetween, joining the tiles by welding the mechanical joint; and thereafter, spray-depositing a spray material over at least a portion of the welded mechanical joint to substantially fill at least a portion of the recess, thereby forming the joined sputtering target.
