  • Patent number: 6686489
    Abstract: A liquid precursor for forming a transparent metal oxide thin film comprises a first organic precursor compound. In one embodiment, the liquid precursor is for making a conductive thin film. In this embodiment, the liquid precursor contains a first metal from the group including tin, antimony, and indium dissolved in an organic solvent. The liquid precursor preferably comprises a second organic precursor compound containing a second metal from the same group. Also, the liquid precursor preferably comprises an organic dopant precursor compound containing a metal selected from the group including niobium, tantalum, bismuth, cerium, yttrium, titanium, zirconium, hafnium, silicon, aluminum, zinc and magnesium. Liquid precursors containing a plurality of metals have a longer shelf life. The addition of an organic dopant precursor compound containing a metal, such as niobium, tantalum or bismuth, to the liquid precursor enhances control of the conductivity of the resulting transparent conductor.

  • Patent number: 6605362
    Abstract: An absorbing ether-like compound including a siliconethoxy, silicondiethoxy, or silicontriethoxy species attached to a naphthalene or anthracene chromophore via an oxygen linkage is used as an organic light-absorbing compound. The absorbing ether-like compound is incorporated into spin-on glass materials to provide anti-reflective coating materials for deep ultraviolet photolithography. A method of synthesizing the light-absorbing ether compounds is based on the reaction of an alcohol-substituted chromophore with an acetoxysilicon compound in the presence of alcohol. A method of making absorbing spin-on-glass materials including the absorbing ether-like compounds is also provided.

  • Patent number: 6518446
    Abstract: The invention relates to a method for producing formoxysilane. A silane of the formula RnSiH4−n, wherein R is an organic or inorganic substituent and n=0, 1, 2 or 3, is converted with carbon dioxide in a solvent in the presence of a catalyst consisting of a compound of a transitional metal pertaining to the subgroup VIIIb of the periodic system. The aim of the invention is to find a catalyst for the method mentioned above. The catalyst should be more simple, easy to produce and thus more cost-effective, easily available in large quantities and being provided with high activity and product selectivity. To this end, a halide of the transitional metal or a compound of the transitional metal are used as catalyst. Said compound is produced by converting a halide of the transitional metal with a nitrile in the presence of the silane of the formula RnSiH4−n.
