Title
(DE) Vorrichtung mit zwei Endblöcken, Anordnung und Sputtersystem damit und Verfahren zur Bereitstellung von HF-Leistung in einem Zielrohr mit dieser Vorrichtung oder Anordnung
(EN) A device having two end blocks, an assembly and a sputter system comprising same, and a method of providing RF power to a target tube using said device or assembly
(FR) Dispositif possédant deux blocs d'extrémité, ensemble et système de pulvérisation comprenant celui-ci et procédé de fourniture de puissance RF vers un tube cible à l'aide de ce dispositif ou ensemble
Abstract
(EN)
A device (602) for use in a sputter system (600), comprising a first end block (631) and a second end block (632), the device being capable of transferring or allowing passage of an RF power signal to one or to both ends or sides of a sputter target tube, and/or for connecting one or both ends ends or sides of a sputter target tube to a terminating impedance (695). An assembly (601) comprising said device and a switching unit (680) adapted for alternatingly applying the RF power to either end or side of the target tube, while terminating the other end or side with an impedance. A method of alternatingly applying RF power to either end or side of the target tube, while connecting the opposite end to a terminating impedance.
