    • 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.

    • PURPOSE: A separation method of a composite member is provided to generate cracks at all times at a fixed position in separation layer by forming a stress concentration layer, in which internal stress to an extent where separation is not generated as the internal stress is left as it is, into the separation, increasing internal stress and preventing the generation of the cracks in the stress concentration layer. CONSTITUTION: A separation layer(12), such as porous single-crystal silicon, is formed on the surface of the first base body such as a silicon wafer. Stress is generated concentrically at a position, where a crack must be generated by working a porous layer, and a stress concentration layer(16) is formed. A nonporous layer(a thin-film)(13), such as nonporous single crystal silicon is formed on the layer surface of the porous layer, in which internal stress is generated, by CVD or the like. Separation energy is given to a multilayer structure(1) from the outside, and internal stress generated is increased. The cranks are generated at positions, where stress is generated concentrically, a stress concentrating layer(16), because the separation energy is energy sufficient for surpassing the breakdown stress of the separation layer, and the composite member is separated into two.
