  • Patent number: 7033874
    Abstract: With keeping an atmosphere including oxygen within a chamber and with a wafer kept at a low temperature, plasma generated within the chamber is biased toward the wafer, and the wafer is subjected to the plasma. A semiconductor layer exposed on the wafer is oxidized into an oxide film. Thus, an oxide film can be formed even at room temperature differently from thermal oxidation. This oxidation is applicable to recovery of an implantation protection insulating film having been etched in cleaning a photoresist film, relaxation of a step formed between polysilicon films, relaxation of a step formed within a trench and the like. Also, before removing a photoresist film used for forming a gate electrode including a metal, a contamination protection film can be formed by this oxidation with the photoresist film kept.

    Abstract: A disk storage medium and a disk drive which reduce friction during landing of the head/slider is described. The minimum fly height area of the head/slider is positioned over a texture free portion of the landing zone on the disk surface landing. In a preferred embodiment, the landing zone of a magnetic disk is a laser texture zone comprising a great number of bumps and is positioned during landing adjacent an area other than the minimum fly height area of the head/slider. The area facing the minimum fly height area of a head/slider has no bumps, i.e. is a bump free zone.
