  • Publication number: 20070209932
    Abstract: The present invention relates to a sputter deposition system and to methods of use thereof for processing substrates using planetary sputter deposition methods. The sputter deposition system includes a deposition chamber having an azimuthal axis. A rotatable member is situated in the chamber and includes a plurality of magnetrons provided thereon. Each magnetron includes a corresponding one of a plurality of sputtering targets. The rotatable member is configured to position each of the magnetrons to direct sputtered material from the corresponding one of the sputtering targets to a deposition zone defined in the deposition chamber. A transport mechanism is situated in the deposition chamber and includes an arm rotatable about the azimuthal axis. A substrate holder is attached to the arm of the transport mechanism and supports the substrate as the arm rotates the substrate holder to intersect the deposition zone for depositing sputtered material on the substrate.

  • Publication number: 20070209926
    Abstract: The present invention relates a physical vapor deposition (PVD) system. e.g. a planetary system, for forming one or more layers of a coating material on a substrate and for treating, or modifying, the substrate surface, which can include the surface of the substrate or a deposited layer of coating material thereon. The PVD system includes a single vacuum (or process) chamber having an ion source and at least one PVD source of the coating material. The ion source, such as a linear ion source, is configured to emit a beam of energetic particles at a substrate for surface modification of the substrate surface, for example, to provide film densification, etching, cleaning, surface smoothing, and/or oxidation thereof. The PVD source(s) of the coating material deposits one or more layers of coating material(s) on the substrate.

  • Publication number: 20070045102
    Abstract: An improved planetary sputter deposition method for sputter depositing an alloy on a substrate wherein the sputter deposited amount, or thickness, of a specific material of the alloy can be controlled so that different substrates can be provided with an alloy having a different composition, i.e. having different percentages of the same materials, thus, reducing the costs of stockpiling multiple alloy targets. The method generally includes providing a substrate and a plurality of targets with each of the plurality of targets being composed of one or more magnetic materials. The targets are sputtered, in sequence, to deposit each of the materials of the plurality of targets on the substrate to provide at least one laminate defining an alloy.

  • Publication number: 20060292705
    Abstract: Method and process for fabricating a device structure for a read head of a mass storage device. A polish stop layer formed of a relatively hard material, such as diamond-like carbon, is positioned between a layer stack and a resist mask used to mask regions of the layer stack during ion milling that removes portions of the layer stack to define a read sensor. The resist mask is removed, after the read sensor is defined, by a planarization process, which eliminates the need to lift-off the resist mask with a conventional chemical-based process. An electrical isolation layer of a material, such as Al2O3, is formed on the masked read sensor. In addition or alternatively, the electrical isolation layer may be formed using an atomic layer deposition (ALD) process performed at an elevated temperature that would otherwise hard bake the resist mask.

  • Publication number: 20060272577
    Abstract: A method and apparatus for decreasing deposition time of a thin film are disclosed. The apparatus includes a removable shield assembly disposed in a vacuum chamber. The shield assembly forms an enclosure to house a substrate during an ALD process. A gas line coupled to the shield assembly introduces a gas into the enclosure to form a thin film on a surface of the substrate. A final valve is associated with the gas line and located proximate the shield assembly such that placement of the final valve with respect to the shield assembly provides fast delivery of the gas into the enclosure.
