All surfaces.
Hereinafter, depositing the mistake of organic matter on the substrate 12 by using the organic deposition device constituted as described above
The embodiment of the present invention is described in more detail in journey.
With reference to Fig. 5 a, substrate 12 and mask 22 are provided respectively to inside chamber 100, to attach it to substrate branch
Support part 10 and mask support portion 20.Substrate 12 and mask 22 can be in alignment with each other by alignment unit.
At this point, organic matter 40 is filled into the crucible 32 of evaporation source 30, and can be arranged on the top of mask cleaning part 50
There are optical window 62 and photochopper 64.
The inside of chamber 100 is formed as by being worked by making vacuum pump 200, for example, 10-4Pascal (Pa) degree
High vacuum state.
If applying power supply to the heating part 34 of evaporation source 30 and heating organic matter 40, the organic matter 40a to gasify passes through spray
Mouth 36 and evaporated to 22 direction of mask, and be selectively deposited on substrate 12 by the slit of mask 22 24, to be formed
Organic layer.
Before the organic matter 40 for heating the evaporation source 30, shield 70 is arranged in the top of mask cleaning part 50, from
And it can make organic matter 40a that can not attach to photochopper 64 or mask cleaning part 50.
As shown in Figure 1, evaporation source 30 and mask cleaning part 50 can be by moving portion 80 and at a predetermined velocity along one
Direction (for example, from left side to right side) is mobile, so as to form organic layer in the whole of substrate 12 with predetermined thickness.Deposition
The thickness of organic layer can be controlled by adjusting the speed.
The organic layer can be the red (R) for constituting organic illuminating element, green (G), blue (B) or white (W)
The luminescent layer of pixel.In the described embodiment, the organic layer of organic electroluminescent device is illustrated as an example, so
And be not limited thereto, the embodiment of the present invention can be used as long as the case where being the need for the deposition of machine layer.
If completing the deposition process, shield 70 is set to be moved to the top of evaporation source 30, to make organic matter 40a not
It is re-directed towards the direction evaporation of substrate 12.
In a period of the deposition process is repeated for multiple substrates 12, it is also possible to sink on the surface of mask 22
Product organic matter 40a.Accordingly, it is possible to may require that cleaning mask 22.
With reference to Fig. 2, light source portion 52 works in the state that mask cleaning part 50 is located at the position facing with mask 22, from
And laser can be generated.The laser 50a generated is passed to scanner section 56 by optical section 54 and after the generation change of path,
And scanner section 56 can sequentially irradiate the laser 50a to the whole surface of mask 22.
The interatomic combination for being deposited on the organic matter 40 on 22 surface of mask is destroyed by the laser 50a, leads to connecting forces
It is weakened, so as to be detached from from mask 22.
As shown in Fig. 2, evaporation source 30 and mask cleaning part 50 are by transferred unit 80 and along a direction (for example, from a left side
Lateral right side) it moves at a predetermined velocity, it can be cleaned to the overall surface of mask 22.
The thickness for being deposited on the organic matter 40 on 22 surface of mask is proportional to frequency of depositing.It can be according to being deposited on mask 22
Thickness and the position of the organic matter 40 on surface and the movement speed for controlling mask cleaning part 50.In addition, direct in the laser 50a
It may deform in the case of being irradiated to mask 22, it is therefore preferred to adjust output, focal length and the irradiation of the laser 50a
Angle.
For organic deposition device according to first embodiment, since mask cleaning part 50 and evaporation source 30 are matched together
It is standby in the inside of chamber 100, so mask 22 can also be cleaned as needed and at any time during the unit process period.
Fig. 6 a are the sectional views for illustrating organic deposition device according to the second embodiment of the present invention, and Fig. 6 b are to cover
