- powdered organic see starting materials converted into a vapor.
- the vaporized starting materials are transported with a carrier gas to a gas inlet member, as described for example in DE 10 2014 116 991 AI.
- the gas inlet organ is a showerhead. It has a surface extension which extends substantially over the substrate to be coated overall.
- a gas outlet plane of the gas inlet member is a plurality of gas outlet openings through which the steam enters the process chamber.
- the gas inlet member is heated.
- Under the gas inlet member is the process chamber, the bottom of which is formed by a substrate holder.

- the deposition process is essentially a condensation of the vapor at the points of the surface of the substrate not covered by the mask.
- the fiction, contemporary substrate holder is actively cooled, for example by passing a coolant. The cooling of the substrate surface, but also of the mask, takes place by heat flow from the mask or from the substrate surface through the substrate into the substrate holder.
- the aforementioned DE 10 2010 000 447 A1 proposes a shielding plate which is brought between the inlet member and the substrate holder during the substrate change or during the mask change.
- Devices for vertical displacement of a substrate holder and a support frame for a mask assembly are also known from
- the support frame and the substrate holder are substantially vertically displaceable independently of each other, wherein during operation of the device first of the support frame of the mask lifting vertically from a mask change position in a Process position is shifted and subsequently the substrate holder is moved from the Substrathalterhub worn of a loading position in a process position.
- the vertical displacement path can be several decimeters. This long relocation path has structural di- mimic the mask of a few microns across. Due to unavoidable vibrations, but also unavoidable tolerances, a reproducible positioning of the substrate holder with respect to the support frame is only possible with difficulty. In addition, due to the long vertical arms that form the support columns, vertical vibrations of the support frame relative to the substrate holder and thus the mask relative to the substrate holder can not be avoided.
- the device according to the invention serves for the deposition of organic substances on a flat substrate, for example for producing optically active planar elements such as monitors, displays or solar cells.
- the device has a reactor housing, in which there is a gas inlet member, in particular in the form of a showerhead, which is heated to an elevated temperature so that the vaporous starting materials introduced thereby into a process chamber do not condense on the gas inlet member.
- the substrate lies on a substrate holder which is separated from a loading Position in which the substrate holder is spaced in the vertical direction from the showerhead, can be brought into a process position, is arranged in the substrate holder at a small vertical distance from the gas outlet surface of the gas inlet member.

- the support frame carrying the mask assembly is also carried by one or more support columns located within the reactor housing, with motion transfer means, such as bellows arrangements, for vertically displacing the support columns from outside the reactor.
- the motion transmission means are thus gas-tight motion transmission means.
- the Substratububplatte and the mask lifting plate are thus arranged outside of the housing.
- captive means are provided with which the support frame is connected in its process position to the substrate holder.
- the binding means are in particular designed such that the substrate holder assumes the supporting function, which otherwise exercise the support columns of the mask lifting device.
- the captive means may be a V-groove and a spherical surface.
- the spherical surface is preferably formed by ball elements that are locally associated with the support frame. These ball elements are based on the oblique edges of the V-groove.

- the device is thus initially set up, as described below. This can be done without a substrate resting on the substrate holder.
- the substrate holder is loaded with the substrate in a vertically lowered loading position. In this case, a pre-adjustment of the substrate.
- the substrate holder is lifted by means of the substrate lifting device until it engages under the support frame with its captive means.
- the mask arrangement may here still be in a raised position, so that the mask does not touch the substrate surface.
- the mask touches the substrate surface when the substrate holder has reached its Fes selungs position relative to the support frame.
- the substrate holder is lifted above this position, but without moving the mask lifting plate.
- the additional lifting movement vertically further removes the support frame from the mask lifting plate.
- the at least one support column of the mask lifting device is preferably fixedly connected only to the support frame, but not to the mask lifting plate, the lower end of the support column moves away from the mask lifting plate, so that the support column is mechanically decoupled from the mask lifting plate. Vibrations of the mask lifting plate are thus not transmitted to the support column and thus not on the support frame.
- the adjusting device is seated on a support frame which is the carrier of the mask carrier on which the mask arrangement rests, the mask arrangement having a frame which clamps the mask.
- the mask frame may be tied to the mask wearer by suitable means such that it retains a defined position with respect to the mask wearer.
- the adjusting device preferably has an adjusting lever, which is rotatably mounted about a rotational axis of a rotary bearing.
- the adjustment lever has two arms. On one arm attacks a vertically mounted control rod.
- the control rod extends through an opening of the reactor housing in an area outside the gas-tight reactor housing, where there is an actuator with which the control rod can be displaced in its direction of extension.
- Such an adjusting device can be designed as a vertical adjustment device or as a horizontal adjustment device.
- a preferred device has both a Vertikaljustier noticed, as well as a Horizontaljustier affection.
- the control rods are guided in control rod guides, there is a certain independence of the position of the actuator unit, which is located at a lower end of the control rod guide.
- the control rods can be fixed with its upper end fixed to the support frame and be connected at its lower end fixed to a housing of the actuator.
- An actuator for adjusting the adjusting lever of the vertical adjusting device and an actuator for adjusting the adjusting lever of the horizontal adjusting device are preferably located in the actuator unit.
- control rods are preferably tie rods, so that it is essential if the control rod guides are transmitted pressure on the support frame or on the housing of the actuator unit attached. They are preferably but also tensile strength connected to the support frame or the housing of the actuator, so that the control rod can act as a train-push rod.
- the mask lifting plate on which, in particular, the support columns are supported for supporting the support frame, can have an opening through which the control rod guides connected to the actuator unit project freely. This arrangement allows the support frame to be displaced relative to the mask lift plate, such as to mechanically decouple the support post from the mask lift plate.
- gas-tight motion transmission means are provided to transmit the vertical movement of the actuator, which is located outside the reactor housing, to the control rods, which are arranged within the reactor housing. Again, preferably Faltenbalgan- orders are used.
