Abstract:
PROBLEM TO BE SOLVED: To enable a smaller miniaturization of a printed circuit board by method wherein a thin film capacitor is made to comprise a metal wheel and a dielectric layer having a specified thickness on the wheel as a structure for the thin film capacitor. SOLUTION: As a simple layout of a thin layer capacitor, a dielectric layer 404 is formed on a metal wheel 402 or a metal layer 402 and a second metal layer 406 is formed on the surface on the opposite side of the layer 404. A layer, which can function as the layer 404 for a buried capacitor and a registor, is very thin and is uniform, can be deposited by a combustion chemical vapor deposition(CCVD) method. The thickness of the layer 404 deposited for the buried capacitor is typically about 0.03 to about 2 microns, preferably the thickness is about 0.1 to about 1 micron and most preferably the thickness is about 0.2 to about 0.6 micron. As the thinner layer 104 has a higher capacitance, the capability to deposit a very thin film of the CCVD method is the favorable point of the CCVD method.
Abstract:
The present invention involves controlled atomization of liquids for various applications such as particle/droplet seeding for laser-based measurements of flow velocity, temperature, and concentration; flame and plasma based elemental analysis; nano-powder production; spray drying for generation of small-sized particles; nebulizers in the production of sub-micron size droplets and for atomizing fuel for use in combustion chambers. In these and other atomizer applications the control of droplet and/or particle size is very critical. In some applications extremely small droplets are preferred (less than a micron), while in others, droplet diameters on the scale of several microns are required. The present invention has the flexibility of forming droplets within a particular range of diameters, wherein not only the size of the average droplet can be adjusted, but the range of sizes may be adjusted as well. The atomizer (4) itself is in the form of a heated tube (44) having an inlet end (48) and an outlet end (50). As liquid travels through the tube it is heated and upon exiting the tube and entering a reduced pressure area the liquid atomizes to form very fine droplets. By electrically heating the tube by passing a current therethrough, the heating adjustment can be performed on-the-fly, allowing droplet size adjustment during operation of the atomizer. Several different embodiments of the atomization device are disclosed.
Abstract:
Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol (N) of polymer solution to a substrate (30) and substantially simultaneously applying an energy source (38) to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame (38) that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.
Abstract:
A coherent material is formed on a substrate ( 10 ) by providing a precursor suspension ( 14 ) in which particulates are suspended in a carrier fluid, and directing the precursor suspension ( 14 ) at the substrate ( 10 ) from a first source ( 12 ). Generally contemporaneously with application of the deposited precursor suspension ( 14 ) to the surface, hot gases, e.g. hot gases produced by a flame ( 16 ), are directed at the substrate ( 10 ) from a remote second source ( 18 ) to fuse the particulates into the coherent material.

The corrosionresistant coating comprises a first distinct layer of a first composition disposed over the substrate, wherein the first distinct layer has a thickness that is not greater than about 10 microns, and a second distinct layer of a second composition disposed over the first distinct layer, wherein the second distinct layer has a thickness that is not greater than about 10 microns an d either the first distinct layer or the second distinct layer is corrosionresistant. Preferably, the thickness of each distinct layer is less than about 1 or 2 microns, more preferably, less than about 0.4 microns. The coating may comprise additional layers. Corrosion-resistant articles, methods of protecting articles, and methods of depositing corrosion-resistant coatings are also described.

Abstract:
A thin film product having a nanostructured surface, a laminate product including the thin film and a temporary substrate opposite the nanostructured surface, a laminate product including the thin film and a final substrate attached to the nanostructured surface and a method of producing the thin film products. The thin film is particularly useful in the electronics industry for the production of integrated circuits, touch screen, flat panel display, printed circuit boards and EMF shielding. The nanostructured surface includes surface features that are mostly smaller than one micron, while the dense portion of the thin film is between 10-200mm. The thin film is produced by coating a temporary substrate (such as aluminum foil) with a coating material (such as copper) using any process. One such method is concentrated heat deposition or a combustion, chemical vapor deposition process. The resulting thin film provides a high level of adhesion to a final substrate, by embedding the nanostructures with the material of the final substrate (such as epoxy resin). The surface of the thin film adjacent the temporary substrate substantially conforms to the substrate surface and has a relatively low peel strength. In this manner, the temporary substrate is easily removed from the thin film after attaching the opposite nanostructured side of the thin film to the final substrate with a resulting, higher peel strength.
