Abstract: PURPOSE: To obtain a semiconductor device whose adaptivity, heat resistance and process adaptivity to a wiring material are obtained by a method wherein a porous semiconductor oxide film is formed, in an atmosphere containing oxygen gas, on a semiconductor circuit element or its wiring pattern which is formed on a semiconductor substrate. CONSTITUTION: A silicon substrate 1 is set inside a chamber (a creation chamber) 21. After that, a porous semiconductor oxide film 5 is formed. In the chamber 21, silicon is used as an evaporation source 23, and a boron nitride(BN) boat 22 is used for a crucible 22a. When electricity is supplied to the BN boat 22, the silicon is heated so as to be evaporated. In order to obtain oxidized ultrafine particles, a mixed gas of O2 and Ar is used as an atmosphere gas. The evaporated silicon is grown as fine particles while it is colliding with the atmosphere gas. At the same time, while the silicon is being oxidized by O2, it is deposited as a porous silicon oxide ultrafine-particle film on the substrate 1 at a distance of 5 cm. The higher the temperature of the evaporation source 23 is, the larger the particle sizes of the ultrafine particles and the larger the molecular weight of the atmosphere gas is.
