  • Patent number: 10087081
    Abstract: The invention provides a method for improving the effectiveness of colloidal silica. The method involves removing enough charged impurities from the colloid to prevent the charged particles from causing the colloid to become a viscous gel. The method however also involves not removing too many charged particles so the silica material doesn't gel by cross-linking with itself. This method is quite effective because it recognizes that materials that have accumulated during the formation of the colloid do perform an important function, but they can perform better at a lower concentration.

  • Patent number: 8926745
    Abstract: A method for preparing a low dielectric constant (low k) material and a film thereof is provided. The method includes the following steps. A substrate is first put into a plasma generating reaction system, and a carrier gas carrying a carbon and fluorine containing silicon dioxide precursor is then introduced into the plasma generating reaction system, so that the carbon and fluorine containing silicon dioxide precursor is formed on the substrate. After that, the carbon and fluorine containing silicon dioxide precursor is converted to a low k material film through heating; meanwhile, a stress of the low k material film is eliminated such that the film has a more compact structure. By means of these steps the carbon and fluorine containing silicon dioxide precursor is still capable of forming a low k material film of silicon dioxide containing a large amount of fluorocarbon, even under various different atmospheres.

  • Patent number: 8298971
    Abstract: The present invention relates to a ceramic powder and special raw material and use thereof. The raw material of the ceramic powder comprises 20-80 mass parts of SiO2, 10-50 mass parts of AlF3 and 0-30 mass parts of regulator. The raw material for preparing the ceramic powder is mixed and crushed, followed by melted into liquid glass at 1200-1400° C., quenched to obtain the ceramic powder. The low temperature co-fired ceramic powder has the following advantages: low sintering temperature (750-850° C.) and controllable sintering shrinkage rate; the dielectric constant of the ceramic block prepared with the ceramic powder is adjustable between 4.5 and 10 (1 MHz), the dielectric loss is less than 0.002, the mechanical strength is high and the preparation process is simple. The ceramic powder may be used for electric devices such as ceramic substrate, resonator, etc. as well as in other microelectronic packaging.

  • Publication number: 20120256336
    Abstract: The present invention relates to a method for producing mesoporous silica particles including a silica-containing outer shell portion with a mesoporous structure. The method includes the steps of: (I) pressurizing a mixed solution containing a hydrophobic organic compound, a surfactant, and an aqueous solvent by a high-pressure emulsification method so as to form an emulsion that includes emulsion droplets containing the hydrophobic organic compound; (II) adding a silica source to the emulsion so as to form a silica-containing outer shell portion with a mesoporous structure on a surface of the emulsion droplets, and precipitating composite silica particles including the outer shell portion and the emulsion droplets on an inner side relative to the outer shell portion; and (III) removing the emulsion droplets from the composite silica particles.

  • Patent number: 8241417
    Abstract: A nanocomposite coating and a method of coating for protecting a product with the nanocomposite coating are presented. Firstly, the nanocomposite coating is prepared, wherein the nanocomposite coating is formed by mixing 22.5˜49.5% nanometer inorganic oxide gel made by a sol-gel method, 45˜74.25% organic solvent and 1˜10% nanometer powder together. Next, the nanocomposite coating is coated onto surfaces of the product evenly by way of spraying, dipping or roll-to-rolling. Lastly, the product coated with the nanocomposite coating is subjected to a room temperature or a heating environment lower than 170 degrees centigrade to make the nanocomposite coating dry for forming nanometer protective films on the surfaces of the product.
