  • Patent number: 6844070
    Abstract: A method of forming a hydrogenated amorphous germanium carbon (a-GeCx:H) film on a surface of an infrared (IR) transmissive material such as a chalcogenide is provided. The method includes positioning an IR transmissive material in a reactor chamber of a parallel plate plasma reactor and thereafter depositing a hydrogenated amorphous germanium carbon (a-GeCx:H) film on a surface of the IR transmissive material. The depositing is performed at a substrate temperature of about 130° C. or less and in the presence of a plasma which is derived from a gas mixture including a source of germanium, an inert gas, and optionally hydrogen. Optical transmissive components, such as IR sensors and windows, that have improved abrasion-resistance are also provided.

  • Publication number: 20040229539
    Abstract: An optical component and method for manufacturing the comprising is disclosed that comprises an IR transmissive substrate. The substrate is coated with an IR transmissive adhesive, comprising hydrogenated amorphous silicon nitride film (a-SiN:H). The adhesive is coated with a top laminate, whereby the optical component obtains a predetermined shape.

  • Publication number: 20040040833
    Abstract: An apparatus that generates at least one plasma that is stable and adjustable in real time. In one embodiment, the apparatus includes multiple plasma sources that can either be “tuned” in real time to generate plasmas that are similar to each other or, conversely, “detuned” to generate dissimilar plasmas. The apparatus may be sued to provide plasma treatment—such as, but not limited to, coating, etching and activation for an article. The invention also provides a plasma source in which operating parameters are adjustable in real time. Methods of providing such plasmas and treating an article using such plasmas are also disclosed.

  • Publication number: 20030072881
    Abstract: Chemical vapor deposition is performed using a plurality of expanding thermal plasma generating means to produce a coating on a substrate, such as a thermoplastic and especially a polycarbonate substrate. The substrate is preferably moved past the generating means. Included are methods which coat both sides of the substrate or which employ multiple sets of generating means, either in a single deposition chamber or in a plurality of chambers for deposition of successive coatings. The substrate surfaces spaced from the axes of the generating means are preferably heated to promote coating uniformity.
