Tubular Magnet Assembly

摘要

A tubular magnet assembly mountable inside a cylindrical target to which the magnet assembly can relatively rotate or translate is disclosed. The magnet assembly discriminates itself from the state-of-the-art in that it comprises both a 'near' magnetic field for confinement of charge in the vicinity of the target in combination with a 'far' magnetic field reaching the substrate for guidance of charge towards the substrate. Such a magnet assembly also has the advantage that it is angularly directional and can be mounted centrally in an ion plating deposition unit.
