Patent ID: 8039045

Claim:
A method of electroless plating on a glass base plate, the method comprising a series of treatments on a surface of a base plate composed of a glass material, the series of treatments including, in order, at least: glass activation treatment to increase quantity of silanol groups on the surface of the base plate at least by a factor of two using an aqueous solution of diluted acid, silane coupling agent treatment, palladium catalyst treatment, palladium bonding treatment; formation of a plating film by means of an electroless plating method, wherein the glass activation treatment is a treatment using sulfuric acid, nitric acid, or a hydrochloric acid of 0.1 wt % to 10 wt % followed by a treatment using hydrofluoric acid of 0. 0001 wt % to 1 wt % wherein the silane coupling agent treatment immediately follows the glass activation treatment.
