Latest Patents
Lammermann holds a patent for a "Method and apparatus for the reactive vapor depositing of metal compounds." This invention involves a method and apparatus for the reactive deposition of vapors of metal compounds onto substrates. The process utilizes the evaporation of at least one metal through an electron beam in a controlled atmosphere with reaction gas at pressures not exceeding 10^-1 mbar. An electrode, positively biased with respect to ground and operating at an acceleration voltage of at least 20 kV, is strategically placed in the vapor stream directed towards the substrate. The metal vapor is generated in an internal chamber surrounding the evaporator, which features a masked orifice opposite the substrate. The introduction of the reaction gas into this chamber allows for the guided flow of both metal vapor and reaction gas towards the substrate.
