  • Patent number: 7718222
    Abstract: A direct vapor deposition (DVD) apparatus and method is taught, that provides a carrier gas flow entraining vapor atoms for the coating of regions on a substrate that are not in line-of-sight. The degree of non line-of-sight (NLOS) coating, hence thickness uniformity around the substrate is a sensitive function of the flow conditions. For a fixed background pressure in the region of deposition, an increase in the uniformity of the coating thickness is accomplished as the flow velocity is reduced. This improvement in uniformity is a result of an increase in the fraction of vapor atoms which deposit in NLOS positions on the substrate such as backside (21) of fiber (65) as indicated by vapor streamlines (51). Vapor impact width (VIW) is the width of the vapor flux impacting on some area of the fiber. Front side coating (FSC) width is the vapor width of atoms impacting on the substrate frontside (22).

    Abstract: The invention relates to a method for coating a substrate with a layer of a material, such as a metal, in which a quantity of electrically conductive material is vaporized in a space with a low background pressure and energy is supplied to the material which is to be vaporized in order to vaporize this material. According to the invention, the material which is to be vaporized, while it is being vaporized, is kept floating, without support, in the space and is enclosed in an alternating electromagnetic field, the alternating electromagnetic field being generated with the aid of a high-frequency alternating current. The invention also relates to a device for coating a substrate and to a substrate.

  • Patent number: 7195797
    Abstract: A vacuum deposition system has been designed to produce thin film based demultiplexers with high throughput and production yields of greater than 25% for use in Dense Wavelength Division Multiplexer (DWDM) systems. The system employs a dense array of high yield fixtures and an ion assisted movable dual electron beam evaporation system. The fixture array increases acceptable yields of narrow band pass filters to 25–75% compared to less than 5% in conventional coating systems used for DWDM. The movable e-beam system allows critical symmetry to be maintained while eliminating significant delays resulting from deposition of two materials from a single electron gun. The vacuum deposition system will enable production of more than 15,000 50–200 GHZ filters which meet specifications for DWDM demultiplexers every 48 hours.

  • Patent number: 7186992
    Abstract: A method of fabricating a polarizing layer using a gas cluster ion beam apparatus (GCIB) is disclosed. The method includes generating a metal-organic gas that includes a metal-organic compound. The metal-organic compound includes a polarizing material, such as iron Fe, Co, or CoFe, for example. The metal-organic gas and a carrier gas are combined to form a composite gas that is supplied to the GCIB. The GCIB processes the composite gas to form a beam of gas cluster ions that include the polarizing material. The beam irradiates an interface surface of a layer of material and at least a portion of the polarizing material remains in contact with the interface surface to form the polarizing layer on the interface surface.

  • Patent number: 7152549
    Abstract: An arrangement for controlling the deflection of an electron beam in a vapor deposition system includes a control unit to which are assigned deflection modules (23, 27) which can be driven in accordance with respective selected functions. By driving these deflection modules, the electron beam can be deflected in two coordinate directions. At least one of the selected functions has a time-changing term via which the periodicity of the deflection of the electron beam (14) changes with respect to this coordinate direction. The term can be pregiven manually or automatically. The invention also relates to a method for controlling the deflection of the electron beam in a vapor deposition system.

  • Patent number: 6902625
    Abstract: An improved crucible cover for multiple pocket electron beam sources has been invented. The invention provides selection between one of the multiple pockets for evaporative heating and a noncontacting, line-of-sight blocking baffle between heated and unheated pockets. In one embodiment, the baffle is formed by the cooperation of a crucible surface groove with a cover feature that extends into the groove. In a second embodiment, the baffle is formed by a barrier extending upwards from the crucible surface between pockets that cooperates with a cover to form the line-of-sight baffle. The crucible and cover in these embodiments accommodate deposits without hindering the ability of the baffle to reduce contamination or interfere with the operation of the source. Additionally, the cover and crucible may be operated separately, with a cover lifting mechanism that lowers the cover to form a baffle and raises the cover to allow the separately controlled rotation of the crucible.

  • Patent number: 6863937
    Abstract: An electron beam physical vapor deposition (EBPVD) apparatus and a method for using the apparatus to produce a coating material (e.g., a ceramic thermal barrier coating) on an article. The EBPVD apparatus generally includes a coating chamber that is operable at elevated temperatures and subatmospheric pressures. An electron beam gun projects an electron beam into the coating chamber and onto a coating material within the chamber, causing the coating material to melt and evaporate. An article is supported within the coating chamber so that vapors of the coating material deposit on the article. The operation of the EBPVD apparatus is enhanced by the inclusion or adaptation of one or more mechanical and/or process modifications, including those necessary or beneficial when operating the apparatus at coating pressures above 0.010 mbar.
