1. A multilayer component comprisingan organic polymer layer;
- andat least one barrier stack;
wherein the barrier stack consists of 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,wherein the barrier stack comprises at least two layers in an amorphous state, andwherein the three successive layers are alternately in an amorphous state and in an at least partially crystalline state.

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.

15. A method of fabricating a multilayer component, the method comprising:
-
providing an organic polymer layer; depositing a polyacrylate interfacial layer on the organic polymer layer; depositing a first layer onto the organic interfacial 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, wherein the barrier stack consists of 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, wherein the barrier stack comprises at least two layers in an amorphous state, and wherein the three successive layers are alternately in an amorphous state and in an at least partially crystalline state. - View Dependent Claims (16, 17)
