  • Patent number: 6709767
    Abstract: Disclosed is a spin-valve sensor employing one or more in-situ oxidized films as cap and/or gap layers in order to achieve an increased GMR coefficient and improved thermal stability. A fabrication method comprises depositing multilayer metallic films on a wafer in ion-beam and DC-magnetron sputtering modules of a sputtering system, and then transferring the wafer in a vacuum to an oxidation module where in-situ oxidation is conducted. When the method is used to form a cap layer, the cap layer may only be partially oxidized. A magnetic-field annealing may be subsequently conducted without the substantial occurrence of interface mixing and oxygen diffusion during the anneal process. The resulting spin-valve sensor exhibits an increased GMR coefficient, possibly due to induced specular scattering of conduction electrons and improved thermal stability mainly due to the protection of an underlying sensing layer from interface mixing and oxygen diffusion during the annealing process.

  • Publication number: 20040007173
    Abstract: In drying a coating liquid such as a resist applied to a substrate under reduced pressure, a coating film in a peripheral portion tends to lose good shape regardless of duration of a drying period, and it is difficult to set an appropriate exhaust flow rate. After the substrate is loaded in an airtight container, a pressure is reduced from atmospheric pressure to a pressure slightly higher than the vapor pressure of a solvent, for example. Then, the solvent actively evaporates from the coating liquid. Here, evacuation is performed initially based on a first flow rate set value Q1, and thereafter, it is performed based on a second flow rate set value larger than Q1. Rounding of the surface in the peripheral portion is corrected by evacuation based on Q1, and more active evaporation of a solvent component is attained by switching to Q2.

  • Patent number: 6599569
    Abstract: A coated plastic container provides for low permeability to gases and vapors. A method and system for coating plastic containers includes applying a thin inorganic oxide layer to the external surface of the containers with plasma-assisted vacuum vapor deposition. For example, the coating can include silica which is bonded to the external surface of the container. This coating is flexible and can be applied regardless of the container's internal pressure or lack thereof. The coating firmly adheres to the container and possess an enhanced gas barrier effect after pressurization even when the coating is scratched, fractured, flexed and/or stretched. Moreover, this gas barrier enhancement will be substantially unaffected by filling of the container. A method of recycling coated plastic containers and a method and system for packaging a beverage using the coated containers are also disclosed.
