  • Publication number: 20160304866
    Abstract: The present invention is intended to provide a novel molecule that inhibits the expression of the periostin gene that is effective in treatment of diseases caused by the expression of periostin except for eye diseases. A drug for a disease caused by the expression of periostin except for an eye disease includes, as an expression inhibitory sequence for the periostin gene, a nucleic acid molecule including a nucleotide that has a base sequence represented by any one of SEQ ID NOs: 1 to 19. The drug for disease according to the present invention can inhibit the expression of the periostin gene. Thus, it can be used for treatment of diseases (except for eye diseases) caused by the expression of the periostin gene, specifically skin diseases, respiratory diseases, gastrointestinal diseases, and the like.

  • Patent number: 6452277
    Abstract: A silicon oxide film is formed to cover a polysilicon plug. A bowing shaped hole is formed. A barrier metal and a metal film are formed, which are successively subjected to prescribed anisotropic etching. Here, because of the RIE-lag effect, the etch rate of the barrier metal becomes smaller in the portion between the side surface of the hole and the metal film than in the other portions, preventing the exposure of the surface of the polysilicon plug. Thus, a semiconductor device ensuring a good electrical connection of metal interconnections is obtained.

  • Patent number: 6287752
    Abstract: A resist pattern is formed on stacked first and second conductive films. After second conductive film is patterned, the patterning of first conductive film follows without removing the remaining resist pattern. Resist pattern is completely removed by etching before the patterning of first conductive film is completed. Thereafter, etching is continued using second conductive film as a mask, and the patterning of first conductive film is completed. Thus, a method of forming a pattern for the semiconductor device in which minute interconnection pattern having a stacked structure is formed without an increase in the number of processing steps can be provided.

  • Patent number: 6228755
    Abstract: Described is a semiconductor device having a buried multilayer wiring structure, in which there is ensured good conductivity among a plurality of wiring layers. A lower wiring pattern is formed from conductive material, and an upper wiring pattern is formed from conductive material. Insulating layers are provided between the lower wiring pattern and the upper wiring pattern. A connection section is formed so as to penetrate through the insulating layers to thereby establish continuity between the lower and upper wiring patterns, as well as to have a greater cross-sectional area at the end facing the upper wiring pattern and a smaller cross-sectional area at the end facing the lower wiring pattern.
