  • Patent number: 7732308
    Abstract: The invention relates to a method for depositing at least one semiconductor layer on at least one substrate in a processing chamber (2). Said semiconductor layer is composed of several components which are evaporated by non-continuously injecting a liquid starting material (3) or a starting material (3) dissolved in a liquid into a tempered evaporation chamber (4) with the aid of one respective injector unit (5) while said vapor is fed to the processing chamber by means of a carrier gas (7). The inventive method is characterized in that the mass flow rate parameters, such as the preliminary injection pressure, the injection frequency, the pulse/pause ratio, and the phase relation between the pulses/pauses and the pulses/pauses of the other injector unit(s), which determine the progress of the mass flow rate of a first silicon-containing starting material and a germanium-containing second starting material (3) through the associated injector unit (5), are individually adjusted or varied.
