The flow of gas deposits a film of a few monolayers of donor compound on the substrate. An optical radiation source (e.g., a femtosecond laser) which produces optical radiation at an instantaneous intensity sufficient to cause non linear or otherwise enhanced interaction between optical radiation photons and the donor compound is used to decompose the donor compound and deposit the metal on the substrate. After an initial deposit of the donor compound is produced, optical radiation can be absorbed and heat the substrate in the localized area of the deposit in order to accelerate the deposition process by thermally decomposing the donor compound.

    Abstract: A vacuum deposition system has been designed to produce thin film based demultiplexers with high throughput and production yields of greater than 25% for use in Dense Wavelength Division Multiplexer (DWDM) systems. The system employs a dense array of high yield fixtures and an ion assisted movable dual electron beam evaporation system. The fixture array increases acceptable yields of narrow band pass filters to 25–75% compared to less than 5% in conventional coating systems used for DWDM. The movable e-beam system allows critical symmetry to be maintained while eliminating significant delays resulting from deposition of two materials from a single electron gun. The vacuum deposition system will enable production of more than 15,000 50–200 GHZ filters which meet specifications for DWDM demultiplexers every 48 hours.

  • Patent number: 6802985
    Abstract: There is provided a method for fabricating electrical wirings capable of being manufactured with low cost and easily applied to large-scale substrates. A photosensitive ground resin film is formed on an insulating substrate by coating process. The ground resin film is subjected to exposure and development processes, by which a ground resin film patterned into a wiring pattern is obtained. Then, on the patterned ground resin film, a low-resistance metal film made of Cu is formed by electroless plating.

  • Patent number: 6730370
    Abstract: A method and apparatus for locally raising the temperature of a material in order to facilitate chemical reactions or processes related to growth or removal of the material utilizes an electrode to apply, in the presence of a growth or removal medium, a controlled succession of thermal spikes or shockwaves of varying energy. The scale of the thermal spikes or shockwaves, and the area of the material affected by the resulting energy transfer, is on the order of a few nanometers to several hundred micrometers, and the duration of the thermal spikes or shockwaves ranges from a few picoseconds to several hundred nanoseconds. The growth or removal medium may be a cryogenic liquid, although other growth media, including liquids, solids, gases in critical or non-critical state, and mixtures of liquids and solids, solids and gases, and liquids and gases, may also be employed.

  • Patent number: 6689426
    Abstract: A liquid compound or a compound solution is kept in contact with the surface of a solid material (synthetic resin, glass, metal, or ceramic), radiation selected from ultraviolet, visible, and infrared is irradiated on the interface between the surface of the solid material and the compound to optically excite the surface of the solid material and the compound, thereby effecting substitution with a chemical species in the compound, depositing or performing etching with the chemical species. Preferably, a transparent window is kept in tight contact with the surface of a solid material to be treated, a thin layer of the liquid compound or the compound solution is interposed between the surface of the solid material and the transparent window by using capillarity, and ultraviolet, visible, or infrared is irradiated through the window. With this treatment, the irradiated portion can be given hydrophilicity, adhesion properties, printing properties, corrosion resistance, and conductivity.

  • Patent number: 6589716
    Abstract: Microoptical systems with clear aperture of about one millimeter or less are fabricated from a layer of photoresist using a lithographic process to define the optical elements. A deep X-ray source is typically used to expose the photoresist. Exposure and development of the photoresist layer can produce planar, cylindrical, and radially symmetric micro-scale optical elements, comprising lenses, mirrors, apertures, diffractive elements, and prisms, monolithically formed on a common substrate with the mutual optical alignment required to provide the desired system functionality. Optical alignment can be controlled to better than one micron accuracy. Appropriate combinations of structure and materials enable optical designs that include corrections for chromatic and other optical aberrations. The developed photoresist can be used as the basis for a molding operation to produce microoptical systems made of a range of optical materials.

  • Patent number: 6580143
    Abstract: A surface modification layer having a surface modification coefficient of 0.1 to 0.5 is formed on the surface of an organic insulating film on a substrate. A metal wiring is provided on the surface of the organic insulating film having the surface modification layer formed at the surface thereof. Thus, the bonding strength between the metal wiring and the organic insulating film is enhanced.

  • Patent number: 6461689
    Abstract: The specular gloss of a polyurethane wear layer of a surface covering is controlled by controlling the thermal conditions of a substrate before and after it is coated with a liquid polyurethane and by controlling the termal conditions of the liquid polyurethane before it is coated on the substrate. The liquid polyurethane is photo-curable or radiation-curable and it contains a matting agent. Changes in specular gloss are attained without changing the composition of the polyurethane or the conditions of photo-curing or radiation curing.

  • Patent number: 6410107
    Abstract: Methods for manufacturing an electrostatic actuator that comprises electrode members having opposing surfaces with a gap disposed therebetween. In an ink jet head, a bottom surface of a diaphragm may be one of the electrodes (common electrode) of an eletrostatic actuator, the diaphragm forming a wall of an ink chamber in the ink jet head that is displaced relatively by an electrostatic force. A hydrophobic film, preferably hexamethyldisilazane (HMDS), is formed on at least one of the opposing electrode surfaces to improve the durability of the electrostatic actuator so that electrostatic attraction between opposing electrode members does not decrease and the opposing electrode members do not stick together. HMDS molecules are smaller than PFDA molecules, and a uniform, variation-free hydrophobic film can therefore be formed even when the gap between opposing electrodes is narrow. Durability and film stability of a HMDS hydrophobic film are also high.
