Title: Chemical vapor growth method of nitrided metallic film and production of electronic device using this
Inventor: MIYAMOTO TAKAAKI
IPC: C23C16/511
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a chemical vapor growth method of a sufficiently intruded metallic film small in the contamination of a chamber and a substrate caused by the generation of dust at the time of film formation and to provide a method for producing an electronic device using the method. SOLUTION: A natural oxidized film 24 on the substrate to be treated is reduced to be removed by a hydrogen active seed, and after that, a metallic film 26 of W, Ta or the like is formed thereon by plasma CVD. Thereafter, this is intruded by an NH active seed or the like as a nitriding agent and is converted into a metallic nitride film such as W, N, TaN or the like. The formation of the metallic film 26 and its nitrification may be repeated plural times. Since metallic compd. gas and intruding agent gas are not simultaneously introduced into a CVD chamber, the dust of side reaction products such as ammonium halide is reduced. Moreover, the nitrification by the NH active seed is the system easy to react, th nitrification is sufficiently executed.

IPC: G01N27/26
Filed: 1985-02-05
Abstract: PURPOSE:To make it possible to easily judge the quality of a plating property with good reproducibility and high reliability within a short time, by contacting a solution containing a metal ion of which the ionization tendency is more noble than that of a metal to be plated, with the metal to be plated prior to plating the surface of said metal to precipitate a noble metal by metal/metal ion exchange reaction. CONSTITUTION:A metal to be plated is immersed in or coated with a solution a metal ion of which the ionization tendency is more noble than that of the metal to be plated, for example, a solution containing a metal such as Ni, Cu or Ag more noble than Zn when Zn is desired to be plated to precipitate the noble metal by metal/metal ion exchange reaction and the plated layer is observed by the naked eye or a loupe. By this method, it is unnecessary to try actual plating and the cleaning degree of a surface to be plated can be judged easily and accurately within a short time. The material used in judgement can be reused by simply removing the precipitated metal by a mechanical method such as buffing or chemical disolution.
