Abstract
This multilayer component (11) for encapsulating an element (12) which is sensitive to air and/or moisture comprises an organic polymer layer (1) and at least one barrier stack (2). The barrier stack (2) comprises at least three successive thin layers (21-23) having alternately lower and higher degrees of crystallinity, the ratio of the degree of crystallinity of a layer of higher degree of crystallinity to the degree of crystallinity of a layer of lower degree of crystallinity being greater than or equal to 1.1.
Claims21
A multilayer component comprising an organic polymer layer;
- and
- at least one barrier stack, wherein the at least one barrier stack comprises at least three successive layers having alternately lower and higher degrees of crystallinity, the ratio of the degree of crystallinity of a layer of higher degree of crystallinity to the degree of crystallinity of a layer of lower degree of crystallinity being greater than or equal to 1.1.
(canceled)
A device comprising an element sensitive to air and/or moisture, which includes a multilayer component an organic polymer layer;
- and
- at least one barrier stack, wherein the at least one barrier stack comprises at least three successive layers having alternately lower and higher degrees of crystallinity, the ratio of the degree of crystallinity of a layer of higher degree of crystallinity to the degree of crystallinity of a layer of lower degree of crystallinity being greater than or equal to 1.1.
A method of fabricating a multilayer component, the method comprising:
- providing an organic polymer layer;
- depositing a first layer onto the organic polymer layer, the first layer having a first degree of crystallinity;
- depositing a second layer onto the first layer, the second layer having a second degree of crystallinity different from the first degree of crystallinity;
- depositing a third layer onto the second layer, the third layer having a third degree of crystallinity different from the second degree of crystallinity;
- wherein the first layer, the second layer, and the third layer form a barrier stack.
