Abstract:
A portable apparatus for thin film deposition on a substrate, comprising:means forming a forechamber having an opening at a side thereof turned in a direction and adapted to be applied in said direction to a substrate for coating said substrate with a thin film, said forechamber being provided with:a vacuum seal surrounding said opening and adapted to press against said substrate,means for connecting said forechamber to a vacuum pump, andmeans for connecting said forechamber to a source of a process gas;means forming a deposition chamber within said forechamber and connected thereto, said deposition chamber having an opening in said direction toward said substrate, said deposition chamber being provided with:a vacuum seal surrounding said opening of said deposition chamber and adapted to press against said substrate,means for connecting said deposition chamber to a vacuum pump,means in said deposition chamber for producing a vapor of a material to be deposited on said substrate, andmeans for connecting said deposition chamber to a source of a process gas; andmeans in said deposition chamber for generating a plasma adjacent said substrate and between said means for producing said vapor and said substrate whereby a thin-film coating is applied by plasma-assisted ion plating to the substrate.
