Applying metal layers onto non-metallic substrate - uses intermediate adhesion promoter layer of inorganic oxide material

摘要

Applying metal layers (5) onto non-metallic substrate (1) comprises using an intermediate adhesion promoter layer (2) of inorganic oxide material. The novelty is that the layers, after being heated to above 100degC, are successively applied as follows: (a) a 1st. closed adhesion promoter layer (2); (b) a metal layer of low layer thickness; (c) a 2nd layer of adhesion promoter of low layer thickness; and (d) a metal layer (5) in its final thickness. The substrate (1) is maintained at above 100degC only to apply the 1st, closed layer of adhesion promoter (2) and the metal layer made of metal islands (3). The substrate (1) is heated to above 200degC. The adhesion promoter (2) and adhesion promoter islands (4) are made of Al2O3, and the metal layer (5) and metal islands (3) of Pt. The adhesion promoter (2) and adhesion promoter islands (4) may alternatively be made of SiO2. ADVANTAGE - The adhesiveness of thin, metal layers on non-metallic substrates, e.g. ceramics or glass, is improved.
