  • Patent number: 8277889
    Abstract: A film formation method is disclosed for depositing a metal film on a target substrate by supplying a metal carbonyl source in gas phase to a surface of the target substrate and decomposing the source near the surface of the target substrate. The method includes a step of preferentially decomposing the metal carbonyl source in an area near the outer peripheral portion of the target substrate when the metal film is being deposited on the surface of the target substrate. As a result, a CO concentration in the atmosphere is increased locally near the outer peripheral portion of the target substrate and the depositing of the metal film on the outer peripheral portion is better controlled.

    Abstract: An inertial masking assembly that allows multiple thin film structures to be deposited on a single substrate by rotation of a shadow mask relative to the substrate. The assembly rotates the position of the shadow mask by the conservation of momentum. The substrate is seated on means for rotating the substrate in a confined orbit within the mask. Abruptly changing the angular velocity of the mask causes the mask to rotate under the substrate, which is mediated by a combination of friction and the substrate's inertia.

  • Patent number: 8110043
    Abstract: A methodology and system for applying coatings onto the interior surfaces of components, includes a vapor creation device, a vacuum chamber having a moderate gas pressure and an inert gas jet having controlled velocity and flow fields. The gas jet is created by a rarefied, inert gas supersonic expansion through a nozzle. By controlling the carrier gas flow into a region upstream of the nozzle an upstream pressure is achieved. The carrier gas flow and chamber pumping rate control the downstream pressure. The ratio of the upstream to downstream pressure along with the size and shape of the nozzle opening controls the speed of the gas entering the chamber. Vapor created from a source is transported into the interior regions of a component using binary collisions between the vapor and gas jet atoms. These collisions enable the vapor atoms to scatter onto the interior surfaces of the component and deposit.

  • Publication number: 20100260940
    Abstract: A system and method for depositing metallic coatings on substrates using a laser printer toner mask. A novel laser printer toner mask provides well-defined masked regions on the substrate and complementary unmasked regions. Metallic vapor from a source may be directed to a substrate with the novel mask adhered to a surface of the substrate where it condenses on the masked surface of the substrate. The mask may then be removed using any suitable technique including simply brushing the material off. Once the mask has been removed, a well-defined metallic coating remains on the unmasked regions of the substrate surface. The system and method may be used on flexible substrates such as those formed of plastic or polyester films.

  • Patent number: 7794545
    Abstract: Provided is a mask which is used to form on the surface of a substrate a plurality of linear film members disposed in parallel to each other by fixing one surface of the mask to the substrate and supplying a film material through the other surface of the mask by the use of a vapor process. The mask includes: a mask body having a plurality of openings corresponding to patterns of the linear film members; and reinforcement ribs which are disposed to cross the openings and which have a function of preventing deformation of the mask body due to the weight thereof. Here, the reinforcement ribs are disposed close to the other surface of the mask in the thickness direction of the openings.
