    Abstract: A method of producing a negative electrode for a lithium secondary cell having thin films of lithium and a sulfide-based inorganic solid electrolyte is provided. In the method, are used a negative electrode base material and an inorganic solid electrolyte source material respectively placed in closed containers. The base material has a surface of lithium metal. The base material and the source material are respectively taken out from the closed containers in a chamber space, which is substantially inactive to lithium and which is insulated from air and provided adjacent to a thin film deposition system. The base material and the source material are transferred into the thin film deposition system without being exposed to the air. In system, the source material is used and a thin film of an inorganic solid electrolyte is formed on the base material. The base material having the thin film is transferred, without being exposed to the air, into a chamber space, which is substantially inactive to lithium.

  • Publication number: 20010055824
    Abstract: The novel method allows monitoring of nitrogen processes by making use of the fact that the incorporation of nitrogen near the surface in silicon, or in a thin silicon nitride layer on the silicon surface, inhibits the diffusion of oxygen during the subsequent thermal oxidation. Accordingly, the oxidation rate of the thermal oxidation is reduced and the growth of the oxide layer on the silicon surface is inhibited. The thickness of the oxide layer is thus used as a measure for the nitrogen content, i.e., for the quality of the nitrogen process.

    Abstract: This pertains generally to precursors and deposition methods suited to aerogel thin film fabrication of nanoporous dielectrics. An aerogel precursor sol is disclosed. This aerogel precursor sol contains a metal alkoxide (such as TEOS) and a solvent, but no gelation catalyst. By a method according to the present invention, such a precursor sol is applied as a nongelling thin film 14 to a semiconductor substrate 10. This substrate may contain patterned conductors 12, gaps 13, or other structures. An independent gelation catalyst (preferably, vapor phase ammonia) is added to promote rapid gelation of the thin film sol 14 at the desired time. One advantage is that it allows substantially independent control of gelation and pore fluid evaporation. This independent catalyst introduction allows additional processing steps to be performed between sol deposition and the onset of substantial gelation. One potential step is to evaporate a portion of the pore fluid solvent.

Then, the oxygen concentration in the atmosphere is reduced to less than or equal to 1% before the surface temperature of the plate-like material to be treated W rises to 200° C. Thereafter, while maintaining the oxygen concentration to be less than or equal to 1%, the elevator means 3 is elevated, so that the plate-like material to be treated W comes close to the hot plate 1, and the surface of the plate-like material to be treated W is heated to be greater than or equal to 400° C.

  • Patent number: 6210749
    Abstract: This invention pertains to a method for producing thermally stable multi-layer coatings and the coatings produced therefrom. The multi-layer coating is comprised of a first coating produced from hydrogen silsesquioxane having a thickness of 1.25 to 2.25 &mgr;m and a second coating comprising silicon dioxide having a thickness of at least 100 nm. The method for producing the first coating comprises applying a fillerless hydrogen silsesquioxane resin composition onto a substrate and thereafter heating the hydrogen silsesquioxane resin at a temperature of 150° C. to 500° C. for a sufficient period of time to produce a crack-free coating having a thickness of 1.25 &mgr;m to 2.25 &mgr;m. The second coating is produced by depositing, preferably by PECVD, silicon dioxide over the first coating at a thickness of at least 100 nm.

  • Patent number: 6171653
    Abstract: An apparatus applies a liquid or viscid coating medium onto a moving material web, especially one made of paper or cardboard. A coating mechanism first applies the coating medium onto an applicator element or an applicator roll, which subsequently transfers the coating medium at a coating location onto the material web in the form of a coating layer. Furthermore, if so desired, a doctoring device can be positioned at a doctor station, adjacent to the coating location, on the downstream side relative to the movement of the material web for the purpose of smoothing and/or metering the coating. The coating apparatus incorporates an apparatus for the generation and/or supplying of a fluid, preferably steam. This apparatus is positioned adjacent to the coating location or to the doctor station on the downstream side relative to the movement L of the material web.

  • Patent number: 6143366
    Abstract: A process is disclosed for reducing the crystallization temperature of amorphous or partially crystallized ceramic films by providing a higher pressure under which the crystallization of the amorphous or partially crystallized ceramic films can be significantly enhanced. The present invention not only improves quality, performance and reliability of the ceramic films, but also reduces the cost for production. By lowering the crystallization temperature, the cost for thermal energy consumed during the crystallization process is greatly reduced. In addition, the interaction or interdiffusion occurring between films and substrates is significantly suppressed or essentially prevented, avoiding the off-stoichiometry and malfunction of thin films, which usually occur in the conventional high-temperature crystallization processes. The process of present invention also decreases the grain size of formed films, thus reducing the roughness of films and producing relatively smooth, good quality films.

  • Patent number: 6120834
    Abstract: An apparatus for forming a film includes a substrate stage, a slit coater and a chamber lid. The substrate stage holds a substrate and defines a lower chamber of an openable low pressure chamber. A treatment solution feed applies the film onto the surface of the substrate held on the substrate stage when the chamber lid (3) is open. The chamber lid defines the low pressure chamber with the substrate stage (1). In the low pressure chamber, the film applied onto the surface of the substrate is subjected to drying by reducing the pressure in the chamber when the chamber lid is closed. Furthermore, according to a method for forming the film, immediately after the film has been applied onto the substrate, the thus applied film is subjected to low pressure drying at the position where the film has been applied.

  • Patent number: 6090443
    Abstract: A multi-layer ferroelectric thin film includes a nucleation layer, a bulk layer, and an optional cap layer. A thin nucleation layer of a specific composition is implemented on a bottom electrode to optimize ferroelectric crystal orientation and is markedly different from the composition required in the bulk of a ferroelectric film. The bulk film utilizes the established nucleation layer as a foundation for its crystalline growth. A multi-step deposition process is implemented to achieve a desired composition profile. This method also allows for an optional third composition adjustment near the upper surface of the film to ensure compatibility with an upper electrode interface and to compensate for interactions resulting from subsequent processing.
