Method for producing an electronic component and electronic component
View Patent ↗A method for producing an electronic component comprising barrier layers for the encapsulation of the component comprises, in particular, the following steps: providing a substrate ( 1 ) with at least one functional layer ( 22 ), applying at least one first barrier layer ( 3 ) on the functional layer ( 22 ) by means of plasma-enhanced atomic layer deposition (PEALD), and applying at least one second barrier layer ( 4 ) on the functional layer ( 22 ) by means of plasma-enhanced chemical vapor deposition (PECVD).
1. A method for producing an electronic component comprising barrier layers for the encapsulation of the component, comprising the steps of:
providing a substrate with at least one functional layer;
applying at least one first barrier layer on the functional layer by plasma-enhanced atomic layer deposition;
applying at least one second barrier layer on the functional layer by plasma-enhanced chemical vapor deposition; and
applying a protective plastic layer having a thickness of greater than or equal to 10 μm on the at least one first and second barrier layers.
2. The method as claimed in claim 1 , wherein the protective layer has a spray coating.
3. The method as claimed in claim 1 , further comprising the step of:
applying a first electrode on the substrate and applying a second electrode on the at least one functional layer of while providing the substrate with the at least one functional layer;
wherein the at least one functional layer comprises an organic functional layer; and
wherein the at least one first barrier layer is applied on the second electrode.
4. The method as claimed in claim 1 , wherein at least one of the at least one first barrier layer and the at least one second barrier layer comprises one of an oxide, a nitride and an oxynitride.
5. The method as claimed in claim 1 , wherein a layer sequence composed of at least two layers comprising different materials is applied as the second barrier layer.
6. The method as claimed in claim 5 , wherein the at least two layers comprising different materials comprise a layer comprising an oxide and a layer comprising a nitride.
7. The method as claimed in claim 1 , wherein at least one of at least one further first barrier layer and at least one further second barrier layer is applied.
8. The method as claimed in claim 6 , wherein the first and second barrier layers are applied alternately one on top of another.
9. The method as claimed in claim 1 , wherein the second barrier layer is applied before the first barrier layer.
10. The method as claimed in claim 1 , wherein the at least one first barrier layer and the at least one second barrier layer are applied at a temperature of less than 120° C.
11. The method as claimed in claim 1 , wherein the at least one first barrier layer has a thickness of greater than or equal to 10 nm and less than or equal to 30 nm.
12. The method as claimed in claim 1 , wherein the at least one second barrier layer has a thickness of greater than or equal to 100 nm and less than or equal to 1000 nm.
13. The method as claimed in claim 1 , wherein the electronic component comprises at least one of an organic light emitting diode and a solar cell.
