  • INLINE CO-SPUTTER APPARATUS
    Publication number: 20100018855
    Abstract: Disclosed is an apparatus and process within a pass-by sputtering chamber, in which standard cathodes and two or more specially-sized cathodes within the sputtering chamber, mounted colinear with the direction of travel of substrates within the sputtering chamber, enabling performance of rapid adjustment of material deposited on a substrate.

  • System and method for controlling thin film defects
    Patent number: 6835290
    Abstract: A system and method for reducing and controlling the number of defects due to carbon inclusions on magnetic media is disclosed. A diamond like carbon protective layer is deposited on magnetic media using a rotary cathode target assembly. The target and cathode are cylindrical in shape and are mounted on holder that allows the target and cathode to rotate while holding a magnet fixed. The target surface is periodically swept in through a plasma which sputters off the surface of the target. This prevents the build up of redeposited material on the target and consequently keeps the target surface cleaner. The reduction of redeposited material on the target surface reduces the number of unwanted particulates which are ejected from the surface, manifesting themselves as disk defects.
