  • Interchangeable magnet pack
    Patent number: 9347129
    Abstract: A sputtering apparatus includes a template having cells. Removable inserts are disposed within the cells. The cells may be circular, triangular, square, diamond shaped, or hex shaped. The removable inserts may be magnetic or non-magnetic inserts. A cover is connected with a first side of the template. A yoke is connected with a second side of the template. The removable inserts are operable to customize or shape a magnetic field over a target. The yoke is operable to provide a return path for the magnetic field.
