  • Fine treatment agent and fine treatment method using same
    Patent number: 7727415
    Abstract: A fine treatment agent according to the present invention is a fine treatment agent for the fine treatment of a multilayer film, including a tungsten film and a silicon oxide film comprising at least one from among hydrogen fluoride, nitric acid, ammonium fluoride and ammonium chloride. Thus, a fine treatment agent which makes fine treatment on a multilayer film, including a tungsten film and a silicon oxide film, possible by controlling the etching rate and a fine treatment method using the same can be provided.

  • Chitin oligomer composition and/or chitosan oligomer composition and processes for preparation thereof
    Publication number: 20070112183
    Abstract: This invention aims to develop a chitin oligomer composition and/or a chitosan oligomer composition wherein the content of an oligomer from a trimer to a decamer is 60% or more, and to develop a process for preparing the above-mentioned oligomer composition. The object of the invention can be achieved by mixing hydrofluoric acid or hydrohalogenated acid other than hydrofluoric acid and hydrofluoric acid with a chitin-based material and/or a chitosan-based material.

  • Process for producing vinyl alcohol polymer compositions
    Patent number: 6596807
    Abstract: A vinyl alcohol polymer composition (II) is produced by a process of providing a reaction liquid comprising a solution containing a vinyl carboxylate polymer and, a first metal alkoxide (I) having at least one functional group and/or an oligomer (I) having at least one functional group obtained from said metal alkoxide (I); a step of simultaneously effecting (a) saponification of said vinyl carboxylate polymer and (b) reaction in which at least part of the functional groups of said metal alkoxide (I) and/or said oligomer (I) participates, thereby obtaining a vinyl alcohol polymer composition (I); and a step of preparing a solution (A) containing said vinyl alcohol polymer composition (I), followed by adding to the solution (A) a second metal alkoxide (II) and/or an oligomer (II) obtained from the metal alkoxide (II) or another solution (B) containing the metal alkoxide (II) and/or the oligomer (II) derived from the metal alkoxide (II), to prepare an intermediate product solution (C), and then removing the sol
