A multilayer structure including a substrate and a first stack of a layer of SiOand a layer of material of the SiONHtype positioned between the substrate and the layer of SiO, in which the layer of SiOand the layer of material of the SiONHtype have thicknesses (e, e) such that the thickness of the layer of SiOis less than or equal to 60 nm, the thickness of the layer of material of the SiONHtype (e) is more than twice the thickness (e) of the layer of SiO, and the sum of the thicknesses of the layer of SiOand of the layer of material of the SiONHtype is between 100 nm and 500 nm, and in which z is strictly less than the ratio (x+y)/5, and advantageously z is strictly less than the ratio (x+y)/10.

Multilayer structure offering improved impermeability to gases

An encapsulation device including two casings made of a flexible polymer material, each delimiting a sealed space, and at least one hydrophobic material filling each of the casings, the casings being stacked and sealingly interconnected at peripheral edges thereof, a sealed space then being defined between the two casings for receiving a device to be encapsulated.
