  • Patent number: 8906456
    Abstract: A device for depositing at least one especially thin layer onto at least one substrate includes a process chamber housed in a reactor housing and includes a movable susceptor which carries the at least one substrate. A plurality of gas feed lines run into said process chamber and feed different process gases which comprise layer-forming components. Said process gases can be fed to the process chamber in subsequent process steps, thereby depositing the layer-forming components onto the substrate. In order to increase throughput, the process chamber is provided with a plurality of separate deposition chambers into which different gas feed lines run, thereby feeding individual gas compositions. The substrate can be fed to said chambers one after the other by moving the susceptor and depositing different layers or layer components.

  • 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.

  • Publication number: 20080274278
    Abstract: The invention relates to a method for the deposition of at least one layer on at least one substrate in a process chamber, whereby the layer comprises at least one component. The at least one first metal component is vaporised in a particularly conditioned carrier gas by means of a non-continuous injection of a starting material in the form of a liquid or dissolve in a liquid and at least one second component as chemically-reactive starting material. The starting materials are alternately introduced into the process chamber and the second starting material is a chemically-reactive gas or a chemically-reactive liquid.

  • Patent number: 7410670
    Abstract: The invention relates to a method and device for depositing at least one layer on at least one substrate in a process chamber. Said layer comprises several components and is insulating, passivating or electrically conductive. The components are vaporized in a tempered vaporization chamber by means of non-continuous injection of a liquid starting material or a starting material dissolved in a liquid using a respective injector unit. Said vapor is guided to the process chamber by means of a carrier gas. It is important to individually adjust or vary the material flow parameters, such as injection frequency and the pulse/pause ratio and the phase relation of the pulse/pauses to the pulse/pauses of the other injector unit, determining the time response of the flow of material through each injector unit. The pressure in the process chamber is less than 100 mbars, the process chamber is tempered and several series of layers are deposited on the substrate during one process step.

  • Publication number: 20080096369
    Abstract: The invention relates to a device for depositing at least one especially thin layer onto at least one substrate (9). Said device comprises a process chamber (1, 20, 11, 11?, 40, 21), housed in a reactor housing (2) and comprising a movable susceptor (20) which carries the at least one substrate (9). A plurality of gas feed lines (24) run into said process chamber and feed different process gases which comprise coat-forming components. Said process gases can be fed to the process chamber in subsequent process steps, thereby depositing the coat-forming components onto the substrate (9). In order to increase the throughput of said method, the process chamber is provided with a plurality of separate deposition chambers (11, 11?) into which different gas feed lines (24, 24?) run, thereby feeding individual gas compositions. The substrate (9) can be fed to said chambers one after the other by moving the susceptor (20) and depositing different layers or layer components.

  • Publication number: 20070009659
    Abstract: The invention relates to a process for depositing at least one layer, which contains at least one first component, on at least one substrate in a process chamber, first and second starting materials, of which at least the first starting material contains the first component, being introduced in gaseous form into the process chamber in a cyclically alternating manner, in order to deposit substantially only one layer at a time of the first component with every cycle. In order to increase the spectrum of suitable staring materials that are available the invention proposes that a first starting material which does not intrinsically allow itself to be deposited in a self-limiting manner, is used and, a limiter formed of a hydrocarbon is introduced into the process chamber in such a way that the depositing of the first component on the substrate automatically ends after completion of the first layer.

  • Patent number: 6849241
    Abstract: The invention relates to a device and method for depositing one or more layers onto at least one substrate placed inside a reaction chamber. The layers are deposited while using a liquid or solid starting material for one of the reaction gases utilized, which are fed via a gas admission unit to the reaction chamber where they condense or epitaxially grow on the substrate. The gas admission unit comprises a multitude of buffer volumes in which the reaction gasses enter separate of one another, and exit through closely arranged outlet openings while also being spatially separate of one another. The temperature of reaction gases is moderated while passing through the gas admission unit.

  • Publication number: 20040013800
    Abstract: The invention relates to a method for supplying a CVD reactor with a liquid starting material entering into a gaseous phase, consisting of a nozzle comprising a liquid channel which leads crosswise into a gas flow channel for producing an aerosol which evaporates with heat. The aim of the invention is to improve the dosability of the generic method or device in such a way that the heat from evaporation is subsequently removed from the gas.
