DIRECT COOLED ROTARY SPUTTERING TARGET

摘要

A rotary deposition target bonded to a backing tube such that the bonding material is applied only at the ends of the rotary sputtering target to form a gap between the rotary sputtering target and the backing tube to enable a target cooling fluid used during the deposition process to contact the target directly and to provide a hermetic seal to contain the cooling fluid within the gap and prevent the fluid from being exposed to the environment within the deposition chamber.
