Abstract
A device for cooling a sputter target of a deposition apparatus utilizes an annular shaped member of high thermal conductivity disposed between the cathode and the target electrode. The member is constructed of a base disposed in a corresponding recess in the cathode, or integrally formed therewith, and a member projecting perpendicularly from the base disposed in a corresponding annular shaped recess in the target electrode. One or more members are disposed proximate a source of cooling water applied to the cathode, and at points of greatest power flux in the target electrode. Upon heating, the target electrode expands radially against the members, thereby effecting reduction in the temperature of the target electrode.
