Abstract

In some embodiments, a first product is provided. The first product may include a substrate, a device having a device footprint disposed over the substrate, and a barrier film disposed over the substrate and substantially along a side of the device footprint. The barrier film may comprise a mixture of a polymeric material and non-polymeric material. The barrier film may have a perpendicular length that is less than or equal to 3.0 mm from the side of the device footprint.

Claims (22)

1. A first product comprising:

a substrate;

a device disposed over the substrate having a device footprint;

a first barrier film disposed substantially along a side of the device footprint; and

a second barrier film disposed over the device,

wherein a footprint of the first barrier film is not more than 3.0 mm wider than the device footprint on one or more sides of the device.

2. The first product of claim 1 , wherein the first barrier film is a mixture of polymeric and non-polymeric material.

3. The first product of claim 1 , wherein the second barrier film comprises a multilayer barrier film comprising a polymeric layer and a non-polymeric layer.

4. The first product of claim 3 , wherein non-polymeric layer comprises an inorganic material.

5. The first product of claim 3 , wherein the non-polymeric layer and the first barrier film comprise the same material.

6. The first product of claim 1 , wherein the second barrier film is a single-layer barrier film.

7. The first product of claim 6 , wherein the single-layer barrier film comprises an inorganic material.

8. The first product of claim 1 , wherein the first barrier film and the second barrier film comprise the same material or combination of materials.

9. The first product of claim 1 , wherein the first barrier film is at least partially disposed over the second barrier film.

10. The first product of claim 1 , wherein the second barrier film is at least partially disposed over the first barrier film.

11. The first product of claim 1 , wherein the second barrier film comprises a plurality of non-polymeric layers and a plurality of polymeric layers.

12. The first product of claim 1 , wherein the first barrier film is a blanket layer that is disposed over the device.

13. The first product of claim 1 , wherein the device footprint encompasses an active device area and an inactive device area, and wherein the first barrier film has a perpendicular length that is not more than 3.0 mm from the side of the device footprint.

14. The first product of claim 1 , wherein the first barrier film does not have a perpendicular length that is greater than 3.0 mm.

15. The first product of claim 1 , wherein the first product comprises at least one selected from the group consisting of: a consumer device, a solar cell, a thin film battery, an organic electronic device, a lighting panel, a lighting source having a lighting panel, a display, an electronic device having a display, a mobile phone, a notebook computer, a tablet computer, a television, and an OLED.

16. The first product of claim 1 , wherein the first barrier film comprises a mixture of an oxide and polymeric silicon.

17. The first product of claim 1 , wherein the first barrier film comprises at least 40% inorganic silicon.
