  • Fluorine-containing polymerizable monomers and polymers, anti-reflection film materials and resist compositions using same
    Patent number: 7105618
    Abstract: The present invention relates to a fluorine-containing polymerizable monomer having a structure of the general formula (1), where each of R1 and R2 is independently a methyl group or trifluoromethyl group, and each of R3 and R4 is independently a hydrogen atom, an alkyl group, a fluorinated alkyl group, a ring structure having an aromatic ring, or an acid-labile protecting group, each of the alkyl group and the fluorinated alkyl group independently having a straight-chain, branched or ring form and having a carbon atom number of 1–25, each of R3 and R4 optionally and independently containing at least one of an oxygen atom and a carbonyl bond.

  • Multilayered water-repellent film and method of forming same on glass substrate
    Patent number: 5856016
    Abstract: The invention relates to a multilayered water-repellent film formed on a glass substrate by the sol-gel process. The film has a first metal oxide layer which is formed on the glass substrate by the sol-gel process and a second water-repellent layer formed on the first layer. As a first method for providing the film with superior durability of water repellency, mechanical strength and chemical resistance, the first layer is prepared by using a mixture of three specific sols which are respectively prepared from metal alkoxides or metal acetylacetonates. As a second method for providing the film with the above advantages, the second layer is prepared by using a coating mixture comprising a fluoroalkylsilane, tin oxide particles doped with antimony oxide, a silicon compound, water and an organic solvent.
