    摘要: A collimator system is disclosed for use in an in-line pass-by sputtering system during the fabrication of recording media to improve the data storage density and read/write performance characteristics of the media. The collimator system includes a collimator shield and a collimator honeycomb. The shield includes a rectangular tube having a flange and a frame at inner and outer ends, respectively. The various components of the shield in part serve to prevent possible contamination of substrates due to target atom accumulation on the chamber walls during the sputtering process. The collimator honeycomb is provided for blocking target atoms from contacting the substrate at low incident angles. The collimator honeycomb is comprised of a plurality of collimators which are identical to each other. In a preferred embodiment, the collimators have a hexagonal cross-section taken from a perspective perpendicular to the substrate. The collimators may also have other geometric shapes. It is also contemplated that more than one collimator honeycomb level be used in alternative embodiments.

    摘要: A cylindrical magnetron sputtering apparatus includes a rotating cylindrical sputtering target, a non-rotating magnet structure within the cylindrical sputtering target and at least one non-rotating trim magnet adjacent an end of the magnet structure. The trim magnets are manipulated during operation of the apparatus to alter a magnetic field produced by the magnet structure within the cylindrical sputtering cathode. As a result the shape of a racetrack discharge plasma formed at an end of the sputtering target is altered such that the formation of an erosion groove is avoided.
