Title Composite material, method for producing the same, and apparatus for producing the same achieved
Abstract

Disclosed is a composite material wherein adhesion between a silicon surface and a plating material is enhanced. A method and an apparatus for producing the composite material are also disclosed. The method for producing a composite material comprises a dispersing/arranging step wherein the surface of a silicon substrate (102), which is a matrix provided with a silicon layer at least as the outermost layer, is immersed into a first solution containing gold (Au) ions, so that particulate or island-shaped gold (Au) serving as a first metal and substituted with a part of the silicon layer are dispersed/arranged on the matrix surface, and a plating step wherein the silicon substrate (102) is immersed into a second solution (24), which contains a reducing agent to which gold (Au) exhibits catalyst activity and metal ions which can be reduced by the reducing agent,

so that the surface of the silicon substrate (102) is covered with the metal or an alloy of the metal (108) which is formed by autocatalytic electroless plating using gold (Au) as a starting point.
