  • Patent number: 5026470
    Abstract: A sputtering apparatus in which the electrode for supporting the substrates upon which thin magnetic films are to be deposited has a polygon-shaped planar coil adjacent to a surface so that the coil can be energized to produce a uniform magnetic field at the surface of the substrates which is oriented normal to the polygon faces of the coil. This apparatus produces uniform easy axis of the thin magnetic films deposited on the substrates during relative motion between the substrates and the target electrode.
