Definitions
- the invention relates to a method for depositing 00005 special organic layers, in which, in a 00006 heated reactor, a non-gaseous outlet stored in a source formed by a container is used - 00008 substance is transported by means of a carrier gas in the gaseous state 00009 from the source to a substrate, where 00010 it is deposited on the substrate.
- OLEDs organic 00013 light-emitting diodes
- It is known as the OVPD procedure 00014 (Organic Vapor Phase Deposition).
- 00015 Organic molecules are used as starting materials, which are present in particular as salts and in granular form 00017, but can also be present in the liquid state 00018. These molecules have a very low vapor pressure.
- the container is an open top 00022 in which the starting material is contained 00023. This trough is inserted into a source zone of the heated 00024 reactor.
- the starting material which evaporates from the granulate bed 00025 or a melt is transported 00026 through the reactor by means of a carrier gas, for example nitrogen 00027.
- the substrate may be at a substrate temperature that is less than 00029 than the source temperature.
- the source material 00030 can be deposited there. Process pressures 00031 of 0.2 mbar are used in the prior art.
- the invention further relates to a device for performing the method with a heatable 00035 reactor associated source in the form of a container for

- 00054 carrier gas is preheated and from bottom to top or
- 00058 flowing carrier gas has the same temperature as that
- 00060 te starting material can no longer be cooled
- 00065 heating elements can also protrude into the starting material.
- 00069 preferably the saturation takes place in the lower third or 00070 lower fifth of the reception chamber.
- the carrier gas is preferably from
- 00075 preferably aluminum.
- the invention further relates to a development of
- 00084 net is for isothermal heating of the carrier gas
- 00086 be that the container has a gas outlet on the bottom side
- 00089 mer can also be designed as an insert. This
- 00091 is inserted into the container. It contains the organic
- the insert can be removed and against
- 00096 outlet opening preferably only one refill opening.
- 00100 wall can be designed as a frit.
- 00101 is the particular powdery or
- 00104 brought temperature.
- This carrier gas then passes through 00105 evenly through the porous partition and 00106 flushes the bed lying on the partition. It is also possible to use liquid starting materials. 00108 Then the liquid is flushed out of the carrier gas, 00109 similar to the case with a wash bottle.
- the 00110 partition can be flat, but it can also be dome-shaped or 00111-shaped.
- the carrier gas and the container are heated by 00113 of the same heater. This is not only technically advantageous. It also offers a high guarantee 00115 that the carrier gas 00116 flowing into the container already has a temperature there that corresponds to the temperature of the starting material.
- heating elements protrude into the starting material, which can be heated separately or are conductively connected to the container wall in order to supply heat to the 00121 starting material.
- the receiving chamber 00122 can be refilled from above.
- a storage chamber can be provided above the receiving chamber 00123.
- this 00124 storage chamber there can be a supply of the starting material 00125.
- This can be fed to the receiving chamber via a lockable channel 00126 in order to refill it.
- the pantry does not need to be heated.
- 00128 It can even be arranged outside the reactor 00129 and only be connected to the reactor 00130 or to the container by means of a refill connection.
- 00131 00132 Embodiments of the invention are explained below 00133 with reference to the accompanying drawings.
- FIG. 1 shows a roughly schematic form, the method 00136 or the device for carrying out the method, as it is prior art

- FIG. 4 shows a third exemplary embodiment of the invention 00147 in a schematic representation
- 00148 00149 5 shows a fourth exemplary embodiment of the invention 00150 in a schematic illustration and 00151 00152 FIG.
- FIG. 6 shows the course of the enrichment of the carrier gas 00153 with the gaseous starting material as a function of the partial pressure of the gaseous starting material in the carrier gas from the location above the 00156 partition.
- the carrier gas 4 is fed to a reactor 1 heated externally from 00159.
- a container 2 is placed in 00161 the reactor, which contains a bed of an external material.
- the starting material sublimates at 00163 the source temperature.
- the gaseous starting material 5 00164 is then ported with the carrier gas 4 to the substrate II trans00165, where it condenses from the gas phase in order to deposit a layer there 00166.
- 00167 00168 The directions shown schematically in FIGS. 2 to 5 replace the 00170 trough-shaped container 2 of the prior art shown in FIG. 1. 00171 00172 00173

- a filter 20 in the form of a frit is provided in front of the gas outlet in the reactor in order to prevent 00249 solid particles or drops from being transported from the container into the 00250 reactor.
- 00251 00252 In a currently not preferred variant of the invention, provision is also made for the carrier gas to be brought into the container at 00254 elevated temperature.
- the 00255 heat, which is required for sublimation of the starting material, can then be at least partially withdrawn from the carrier gas 00257, the carrier gas then cooling to the 00258 container wall temperature, so that isother00259 me conditions prevail again.
- the carrier gas can be heated by heating the 00262 partition 16.
- the intermediate wall 16 can be made of metal.
- 00264 00265 In the exemplary embodiments explained with reference to the figures, the container is continuously flowed through from below to 00267 above. However, the invention also includes such embodiments in which the gas flow runs the other way around, namely from top to bottom.
