  • Publication number: 20060226121
    Abstract: An interlayer insulating film composed of an organic compound film containing an organic component as a main constituent is deposited on a semiconductor substrate. Then, etching is performed with respect to the interlayer insulating film by using a plasma derived from an etching gas containing an ammonia gas as a main constituent. As a result, active hydrogen is generated in the plasma derived from the ammonia gas to decompose the organic component into hydrogen cyanide, whereby etching proceeds. Since a surface of the organic compound film is efficiently nitrided by nitrogen generated from the ammonia gas, the sidewalls of a depressed portion in the organic compound film are protected so that an excellent anisotropic property is provided. Since the etching gas does not contain a component which oxidizes the organic compound film, the problem does not occur that a gas is generated from the organic compound film in a subsequent heat treatment process.

  • Publication number: 20050245097
    Abstract: A Lewis acid-base reaction is caused, in a solution, between a first monomer corresponding to a Lewis acid and a second monomer corresponding to a Lewis base, so as to generate a monomer adduct in which the first monomer and the second monomer are bonded to each other through weak electric interaction. Next, the solution including the monomer adduct is applied on a substrate so as to form a supramolecular solid thin film made of the monomer adduct. Then, the supramolecular solid thin film is heated so as to cause a polymerization reaction between the first monomer and the second monomer within the supramolecular solid thin film, thereby forming a polymer thin film.

  • Publication number: 20050181594
    Abstract: A method for forming an organic/inorganic hybrid insulation film includes the following steps. An organic silicon compound containing siloxane bonds is vaporized, the vaporized organic silicon compound is transported to a reaction chamber maintaining the compound in a monomer state, and then, the organic/inorganic hybrid insulation film having a main chain structure where siloxane parts and organic molecule parts are alternately combined on a substrate installed in the reaction chamber is formed by plasma-polymerizing the vaporized organic silicon compound in the reaction chamber.

  • Publication number: 20050173804
    Abstract: The interlayer dielectric film made of a three-dimensionally polymerized polymer is formed by polymerizing: first cross-linking molecules having three or more sets of functional groups in one molecule providing a three-dimensional structure; and a second cross-linking molecule having two sets of functional groups in one molecule providing a two-dimensional structure. In the three-dimensionally polymerized polymer, dispersed are a number of molecular level pores formed by the polymerization of the first and second cross-linking molecules.

  • Patent number: 6873052
    Abstract: An organic-inorganic hybrid film is deposited on a substrate by introducing, into a vacuum chamber, a gas mixture of a silicon alkoxide and an organic compound and generating a plasma derived from the gas mixture. Then, a hydrogen plasma process is performed with respect to the organic-inorganic hybrid film by introducing, into the vacuum chamber, a gas containing a reducing gas and generating a plasma derived from the gas. As a result, an organic component in the organic-inorganic hybrid film eliminates therefrom and numerous fine holes are formed in hollow portions from which the organic component has eliminated, whereby a porous film composed of the organic-inorganic hybrid film is obtained.

  • Patent number: 6780779
    Abstract: After successively depositing a first metal film and a first silicon oxide film on an insulating film formed on a semiconductor substrate, etching is carried out by using a first resist pattern as a mask, so as to form a first interlayer insulating film having openings from the first silicon oxide film and first metal interconnects from the first metal film. A third interlayer insulating film of an organic film is filled in the openings of the first interlayer insulating film, and the first interlayer insulating film is etched by using a hard mask. A second metal film is then filled in a space in the second interlayer insulating film, so as to form second metal interconnects.
