    摘要: A method of forming micro holes metal membrane by inkjet printing spray micro droplets of a catalyst in the holes after the substrate surface is treated. The catalyst adsorbs and dries on the inner walls of the holes. After that, the surface properties of the substrate are changed so that the coating solution readily enters the holes and forms a membrane on their inner walls. This can avoid incomplete metal coating due to residual air in the holes and forming a disconnected circuit. Moreover, the adhesive force between the inner wall of the holes and the metal improves the situation of coated layer peeling. The method reduces the use of precious catalyst, the fabrication procedure, and the production of photo resist etching waste. Since it does not require expensive equipment and space for exposure, developing, laser drilling, the method lowers the production cost and satisfies the environmental protection requirements.
