    Abstract: Intermetal dielectric (IMD) and interlevel dielectric (ILD) that have dielectric constants (K) ranging from 2.0 to 2.6 are prepared from plasma or photon assisted CVD (PACVD) or transport polymerization (TP). The low K dielectric (LKD) materials are prepared from PACVD or TP of some selected siloxanes and F-containing aromatic compounds. The thin films combine barrier and adhesion layer functions with low dielectric constant functions, thus eliminating the necessity for separate adhesion and barrier layers, and layers of low dielectric constant. The LKD materials disclosed in this invention are particularly useful for <0.18 &mgr;m ICs, or when copper is used as conductor in future ICs.

    Abstract: An applying method for an adhesive according to an embodiment includes the following steps. First, gas is exhausted from a first exhaust pipe, so as to eliminate a part of the gas in a closed container. Next, the gas continues to be exhausted from the first exhaust pipe, so as to have the adhesive in the transmission pipeline become bubbled, and also to convey the bubbled adhesive to reach the supply vent. Later, gas is exhausted from the second exhaust pipe and continues to be exhausted from the first exhaust pipe, so as to greatly exhaust the gas in the closed container, and also to increase bubbling in the adhesive. Subsequently, the gas continues to be exhausted from the second exhaust pipe and ceases to be exhausted from the first exhaust pipe, so as to cause the adhesive to reach a gasified state. Also the gasified adhesive is supplied to the closed container from the supply vent, so that the gasified adhesive can adhere to and coat above the SiO2 layer.

  • Publication number: 20040011288
    Abstract: The present invention provides a polymer coating method. In the method, in a vacuum chamber, a low temperature monomer evaporation chamber is used to heat a liquid monomer and a cooled substrate at a temperature lower than the liquid monomer reservoir or vapor. The liquid monomer is allowed to condense on the cooled substrate surface where it is polymerized by a radiation source. The process depends on the vapor pressure difference between liquid in the monomer source and liquid condensed on the surface of the cooled substrate. The film thickness is dependent on the temperature difference between the monomer reservoir and the substrate, and the time that is required to move the coated substrate from the evaporation chamber to the cure station. The method is suitable for forming very thin, uniform, pinhole-free, polymer coatings from a variety of monomers, having at least two olefinic groups per molecule, on a variety of substrates.

    Abstract: Nitroxide mediated free radical polymerization of vaporized vinyl monomers, including acrylic acid (AAc), styrene (St), N-2-(hydroxypropyl) methacrylamide (HPMA) and N-isopropyl acrylamide (NIPAAm), on silicon wafers is demonstrated. FTIR, ellipsometry and contact angle goniometry were used to characterize the chemical structures, thickness and hydrophilicity of the films. The growth of film is linearly proportional to its reaction time, leading to the easy and exact control of polymer film thickness from nanometers to submicrons. The capability of polymerizing various monomers allows us to fabricate various functional polymer brushes. The reversible thermo-responsiveness of a 200 nm thick grafted poly(NIPAAm) film in aqueous solution is demonstrated with over 50% change in thickness at its lower critical solution temperature. A tri-block copolymer of poly(AAc)-b-polySt-b-poly(HPMA) is successfully synthesized, proving the renewability of TEMPO-mediated polymerization at vapor phase.

  • Patent number: 6602547
    Abstract: A new fluidized bed particle coating method is disclosed by the use of which coatings can be uniformly and conveniently deposited on the surfaces of fluidized particulate materials by vapor deposition processes at temperatures lower than those of the heated coating precursor transport lines. By this method, particle materials with relatively low surface temperatures may be brought into close proximity with a coating precursor containing gas stream characterized by a substantially higher gas volume temperature in such a way that the vaporized precursor molecules are caused to adsorb or condense on the relatively cold particle surfaces without also condensing on any other surface. Further, if the adsorbed precursor molecules are capable of reacting or polymerizing on the relatively cold particle surfaces, thus forming substantially continuous coatings on those surfaces, they may do so without also depositing such coatings on any other surfaces.

  • Patent number: 6596134
    Abstract: A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure.
