Abstract
A barrier layer stack is described. The barrier layer stack includes: (i) a barrier material including defects; (ii) a seal covering the defects of the barrier material; and (iii) wherein, in an operational state of the barrier layer stack, presence of the seal reduces or prevents diffusion of vapor and/or gas molecules through the defects of the barrier material.
Claims17
A barrier layer stack, comprising:
- a barrier material including defects;
- a seal completely covering said defects of said barrier material, wherein said defects include recesses inside barrier material and a substantial amount of said seal does not protrude inside said recesses;
- and
- wherein, in an operational state of said barrier layer stack, presence of said seal reduces or prevents diffusion of vapor and/or gas molecules through said recesses inside said barrier material.
1 more element
A device assembly comprising:
- an underlying device;
- and
- an encapsulant at least partially encapsulating said underlying device, and said encapsulant including:
- a barrier material including defects;
- a seal completely covering said defects of said barrier material, wherein said defects include recesses inside barrier material and a substantial amount of said seal does not protrude inside said recesses;
- and
- wherein, in an operational state of said barrier layer stack, presence of said seal reduces or prevents diffusion of vapor and/or gas molecules through said recesses inside said barrier material.
4 more elements
A preserving packaging comprising:
- an object that is sensitive to vapor and/or gas molecules;
- and
- an encapsulant at least partially encapsulating said object, and said encapsulant including:
- a barrier material including defects;
- a seal completely covering said defects of said barrier material, wherein said defects include recesses inside barrier material and a substantial amount of said seal does not protrude inside said recesses;
- and
- wherein, in an operational state of said barrier layer stack, presence of said seal reduces or prevents diffusion of vapor and/or gas molecules through said recesses inside said barrier material.
4 more elements
A composition of a barrier layer stack, comprising:
- a barrier material having defects which allow transport of gases and/or vapor, and said barrier material including at least one member chosen from a group comprising metal, metal oxide, metal nitride, metal oxy-nitride, metal carbo-nitride, and metal oxy-carbide -nitride;
- and
- a non-conformal seal including a polymeric material that is at least one member chosen from a group comprising acrylates, epoxies and polyurethanes.
