Definitions
- the invention relates to a method and a device
- 00006 flows by introducing a gas stream into one
- the invention is therefore based on the object
- 00037 essentially corresponds to the gas pressure in the tank, a partial
- 00038 gas stream is branched off, which to displace the
- 00040 current is measured, by varying the pressure
- a partial gas mass flow is set, the under
- 00043 corresponds to the setpoint of the liquid volume flow.
- 00044 method is preferably further developed in that
- 00046 is as the gas stream.
- the gas stream is also preferred
- 00050 brought condition is fed to a CVD reactor.
- the liquid stream can be atomized in a pulsed manner
- 00060 corresponds to pressure in the tank, a partial gas flow can be branched off
- 00063 tank is directed, with a regulator with which
- 00066 mass flow is adjustable so that its corresponding
- the device can preferably be one
- 00070 be classified.
- the liquid flow can further be one 00071 in particular pulsating atomizer nozzle are fed 00072.
- the aerosol 00073 generated by the atomizing nozzle can be fed after evaporation in the gaseous state to a process chamber of a CVD reactor.
- 00075 00076 An embodiment of the invention is explained below 00077 with reference to the accompanying drawings.
- the drawing 00078 shows schematically the structure of a device for carrying out the method 00079.
- 00080 00081 A gas stream, for example 00082 hydrogen or nitrogen or another 00083 inert gas, flows from a feed line 13 through a gas mass flow controller 2.
- the gas stream 00085 flow Q1 provided by the gas mass flow controller 2 flows past a branch 12 to a pressure 00086 controller 1, which keeps the pressure in the region of the branch 12 constant at a pressure Pl.
- the excess gas flows out of a discharge from the pressure regulator 00089 1.
- 00090 00091 At branch 12, a comparatively small partial gas 00092 stream Q2 is branched off.
- the partial gas flow Q2 is about 100 times smaller than the gas flow Q1, which essentially flows through the discharge line 14 as a gas flow Q4.
- 00095 00096 The partial gas flow Q2 flows through a gas mass flow meter 3.
- the flow resistance of the gas mass 00098 flow controller is comparatively low.
- the atomizing nozzle 9 can be pulsed and forms one
- 00116 mer is preferably used to separate ferroelectrical
- the device also has a control element 7, which
- a volume flow can be determined.
- control element 7 controls this volume flow Q2 to one
- the regulatory body 00133 if influenced by the regulator.
- 00134 7 can also control an atomizing nozzle 9.
- 00135 atomizer nozzle 9 can be continuous or pulse-white
- control element 7 varies the default value for
