    摘要: A dry etching method is disclosed, in which the pressure of etching gas in a reaction chamber, the bias voltage applied to article to be etched, and the temperature of the article to be etched object are set so that the etching rate for the article to be etched is greater than 0.2 .mu.m/min, a ratio of the length of side etching in the article to be etched to the depth of etching therein is less than 1/100, and a ratio of the etching rate for the article to be etched to the etching rate for a mask formed thereon is greater than 10. Thus, the dry etching method can satisfy three requirements (that is, a high etching rate, a high selection ratio and marked anisotropy in etching) at the same time, although conventional dry etching methods can satisfy only two of three requirements.

    摘要: A deep trench is formed by carrying out etching by using an etching gas free of carbon and silicon, which contains at least one member selected from the group consisting of fluorine, chlorine and bromine, while maintaining an article to be etched at such a temperature that the reaction probability between silicon and fluorine, chlorine or bromine contained in the etching gas is less than 1/10 of the reaction probability at 20.degree. C. According to this method, a deep trench having a very narrow width and a large aspect ratio, which cannot be formed according to the conventional method, can be formed very promptly with much reduced side etching.

    摘要: In a thin film deposition apparatus, means for depositing a film on a substrate and means for etching the deposited film to make flat the surface thereof, are provided in a reaction vessel independently of each other. This apparatus can rapidly deposit the film without rising the temperature of the substrate excessively. Further, since the deposition means and etching means are independent of each other, the deposition of a film on the substrate and the planarization of the surface of the deposited film can be achieved under various conditions.

    摘要: A semiconductor device having a large-capacitance capacitor in which an insulator film is formed underneath a film made of a material having a high dielectric constant, such as tantalum oxide, in such a manner that a portion of the insulator film underneath a defect region which is undesirably thin is thicker than other portions of the insulator film, thereby preventing occurrence of a failure in terms of dielectric strength and deterioration of the lifetime of the capacitor which would otherwise be caused by the existence of the defect region. Also disclosed is a process for producing such semiconductor device. Thus, it is possible to effectively prevent occurrence of problems which would otherwise be caused when a material having a high dielectric constant, such as tantalum oxide, is employed as a dielectric film of a capacitor, so that the reliability of a semiconductor having a large-capacitance capacitor is greatly improved.

    摘要: A copper film is formed by bringing the vapor of an inorganic compound of copper, such as cuprous nitrate that vaporizes upon heating, into contact with a reducing gas in the reaction chamber, so that copper ions are reduced into metal copper that is to be deposited on a substrate. The obtained copper film exhibits very good step coverage and contains very little impurities, lending itself well for forming interconnections of a semiconductor device that has a high degree of integration.
