    Abstract: In a sputtering device of the present invention, a long film is guided by a plurality of concave guide rolls. Pressure imposed on the long film from the plurality of concave guide rolls is strong as near as an end and is weak as near as the center. Accordingly, the long film is substantially supported in an end portion of each of the concave guide rolls. Since wrinkles generated on the long film are not subjected to strong pressure from the concave guide rolls when passing through the concave guide rolls, these wrinkles do not turn to folds and pass through as they are.

    Abstract: This invention relates to a vacuum vapor-deposition apparatus for forming vapor-deposited films on a base film, thereby to produce vapor-deposited films, and also to a method of producing vapor-deposited films. In the vacuum vapor-deposition apparatus, the synchronizing means equalizes the circumference velocity v1 of the coating roll and the circumference velocity v2 of the takeup guide roll. Hence, v1=v2. Therefore, the takeup guide roll never rubs the vapor-deposited layer provided on the surface of the film. This eliminates the possibility that the vapor-deposited layer has scratches. The vapor-deposited layer can therefore possess desired properties.

  • Patent number: 7410542
    Abstract: A roll to roll, film forming system overcoming the shortcomings of current roll to roll processing is presented; The roll to roll enabled cartridge is loaded with a bolt of fresh flexible substrate. A skate couples with a cartridge, forms a seal with the cartridge's bottom aperture and drives the cartridge along a rail to an array of deposition heads. A head mates with the cartridge top forming a pressure seal around the variable area deposition aperture. The mating of the skate, cartridge and head form a pressure vessel wherein a film forming environment may be maintained. As the substrate advances past the deposition aperture a layer is formed, potentially from bolt end to bolt end. Device growth continues from one head to another, as grown device encapsulation seal inclusive, aperture environmental seals applied, labeled cartridge is routed to dock, skate returns to system start.

  • Patent number: 7294283
    Abstract: The preferred embodiments described herein provide a Penning discharge plasma source. The magnetic and electric field arrangement, similar to a Penning discharge, effectively traps the electron Hall current in a region between two surfaces. When a substrate (10) is positioned proximal to at least one of the electrodes (11, 12) and is moved relative to the plasma, the substrate (10) is plasma treated, coated or otherwise modified depending upon the process gas used and the process pressure. This confinement arrangement produces dramatic results not resembling known prior art. Using this new source, many applications for PECVD, plasma etching, plasma treating, sputtering or other plasma processes will be substantial improved or made possible. In particular, applications using flexible webs (10) are benefited.

  • Patent number: 7156960
    Abstract: A method for the deposition of a metal layer on a substrate (1) uses a cold plasma inside an enclosure (7) heated to avoid the formation of a metal deposit at its surface. The enclosure has an inlet (21) and an outlet (22) for the substrate with a source of metal vapor between them, made up of an electrode to form a plasma (6) with the substrate or a separate electrically conducting element as a counter-electrode. The deposition metal is introduced in the liquid state in a retention tank (8) and is maintained as a liquid at an essentially constant level during the formation of the metal layer on the substrate. An Independent claim is included for the device used to put this method of coating a substrate into service.

  • Patent number: 6942768
    Abstract: A system for coating band-shaped material, where the band-shaped material travels through at least one process chamber in which there is a vacuum, and at least one cooling roller. On the peripheral surface of each cooling roller are at least two magnetron sputter sources that are arranged separate from one another in magnetron chambers, which are formed by separate magnetron chamber walls and allow each chamber to be evacuated, so the pressure in the magnetron chamber can be maintained higher than that in the process chamber. The magnetron chamber walls and the magnetron sputter sources can be mounted on a common carriage, which is displaceable parallel to the cooling roller axis. The result is the reduction in the maintenance costs in cleaning of the magnetron chamber walls and at the same time improvement of the separation of gas between the magnetron chambers and the process chamber.

    Abstract: The present invention is a deposition system for the production of coated substrates that provides a first deposition process that subsequently feeds a second deposition process and where the two deposition processes are occurring concurrently. The consecutive deposition system includes two dynamically isolated deposition chambers. The substrate is helically wrapped about a cooling block within the first deposition chamber such that the tape is exposed to a deposition zone a number of times sufficient to correspond to the desired film thickness. A shielding element may be included in the second deposition chamber to limit the size of the second chamber deposition zone and thus the film thickness of the second coating layer.

    Abstract: Disclosed herein is an improved gas gate for interconnecting regions of differing gaseous composition and/or pressure, more particularly between atmosphere and a vacuum. The gas gate includes a cylinder within a housing situated between the regions of differing gaseous pressure, wherein the gas gate provides for choke mode transonic flow of air leaks between the regions. A web of substrate material is adapted to move between the regions with at least one roller in a first region and at least one roller in a second region. The rollers are positioned to create sufficient tension as the web advances over the top peripheral portion of the cylinder between the two regions or under the bottom peripheral portion of the cylinder between the two regions.

  • Patent number: 6869484
    Abstract: A continuous feed coater for coating a length of substrate with vaporized or sprayed material, is disclosed. A specific example is a roll-to-roll coater which includes two lower supply rollers for supporting two webs of uncoated material, and two upper take-up rollers for supporting the webs after they are coated. A central web-support forms a plenum that acts as a deposition chimney or chamber by bringing the two webs into close proximity to each other to form two large walls of the plenum. The ends of the webs are sealed using side dams to form the chimney with a rectangular cross section such that the vapor cannot exit from the edges of the material. The vaporized coating constituents to be deposited on the rolled material are directed into the deposition plenum from a coating material supply source located at the bottom of the plenum, and are exhausted through the top of the plenum.

  • Patent number: 6821348
    Abstract: In one embodiment, the invention is directed to aperture mask deposition techniques using aperture mask patterns formed in one or more elongated webs of flexible film. The techniques involve sequentially depositing material through mask patterns formed in the film to define layers, or portions of layers, of the circuit. A deposition substrate can also be formed from an elongated web, and the deposition substrate web can be fed through a series of deposition stations. Each deposition station may have an elongated web formed with aperture mask patterns. The elongated web of mask patterns feeds in a direction perpendicular to the deposition substrate web. In this manner, the circuit creation process can be performed in-line. Moreover, the process can be automated to reduce human error and increase throughput.
