Patent ID: 8562799

Claim:
An end-block for rotatably carrying a target around an axis of rotation in an evacuable sputtering apparatus, said end-block comprising a subset of at least two of the following means: a driven means for providing a driving force of rotation to the target, said driven means covering a driven means range on said axis, said driven means range being defined as a perpendicular projection of said driven means on said axis; a rotatable electrical contact means covering a contact means range on said axis, said contact means range being defined as a perpendicular projection of said contact means on said axis; and a number of coolant seal means that are relative rotatable between fixed and rotatable parts, the number of coolant seal means covering corresponding coolant seal means ranges on said axis, said coolant seal means ranges being defined as perpendicular projections of said corresponding coolant seal means on said axis; wherein at least two different means out of said subset of means are arranged radially to one another, so that at least two ranges corresponding to said at least two different means overlap one another on said axis; and wherein said driven means is one of a pulley of a pulley-belt system, a driven gear of a worm-gear system, a driven gear of a cylindrical gear-gear system, or a driven gear of a conical gear-gear crossed axis system.
