  • Patent number: 9409793
    Abstract: The present invention relates to a novel spin coatable composition comprising (a) metallosilicic acid; (b) at least one compound comprising two or more 4-hydroxyphenyl groups; and, c) a solvent. The component b) can be a 4-hydroxyphenyl compound of structure (I) wherein W is a linking group chosen from the group consisting of an organic linking moiety, a heteroatom containing linking moiety and a direct valence bond, m is a positive integer of 1 and n is a positive integer equal to 1 or and Ri, Rii, Riii and Riv are independently chosen substituents from a group consisting of hydrogen, (C1-C6) alkyl, (C1-C6) alkoxy, (C6-C20) aryl, halides (such as Cl, I, F), hydroxyl, alkylcarbonyl (alkyl-C(?O)—), alkylcarbonyloxy (alkyl-C(?O)—O—), alkyloxycarbonyl (alkyl-O—C(?O)—), alkyloxycarbonyloxy (alkyl-O—C(?O)—O—) and mixtures of these; and a solvent. The present invention further relates to processes using the novel compositions.

  • Publication number: 20070105040
    Abstract: The present invention relates to an undercoating composition for a photoresist comprising a polymer which is insoluble in an aqueous alkali developer but becomes soluble prior to development, and a photoacid generator which produces a strong acid upon exposure to radiation, and further where the polymer is transparent at the exposure radiation. The invention also relates to a process for imaging the undercoating composition.

  • Publication number: 20070015080
    Abstract: The present invention provides for a light-sensitive photoresist composition useful for imaging thick films, comprising a polymer which is insoluble in an aqueous alkali developer but becomes soluble prior to development, a photoacid generator which produces a strong acid upon irradiation and a photobleachable dye. The invention further provides for a process for imaging the photoresist of the present invention, especially where the thickness of the photoresist is up to 200 microns and where the process comprises a single exposure step.
