Abstract

Claims (35)

1. A first product comprising:

a substrate having a first surface, a first side, and a first edge where the first surface meets the first side;

a device disposed over the substrate and in direct contact with the first surface, the device having a second side;

wherein at least a first portion of the second side is disposed within approximately 3 mm from the first edge of the substrate; and

a first barrier film that covers at least the first portion of the second side of the device,

wherein the first barrier film comprises a mixture of polymeric silicon and inorganic silicon.

2. The first product of claim 1 , wherein at least the first portion of the second side of the device is disposed within approximately 2 mm from the first edge of the substrate.

3. The first product of claim 1 , wherein at least the first portion of the second side of the device is disposed within approximately 1 mm from the first edge of the substrate.

4. The first product of claim 1 , wherein at least the first portion of the second side of the device is disposed within approximately 0.5 mm from the first edge of the substrate.

5. The first product of claim 1 , wherein at least the first portion of the second side of the device is disposed within approximately 0.1 mm from the first edge of the substrate.

6. The first product of claim 1 ,

wherein the device comprises an active device area and an inactive device area; and

wherein at least a portion of the active device area of the device is disposed within 0.1 mm from the first edge of the substrate.

7. The first product of claim 1 , wherein the first barrier film is disposed over at least a portion of the device.

8. The first product of claim 1 ,

wherein the device comprises a plurality of sides; and

wherein the first barrier film covers each of the plurality of sides of the device.

9. The first product of claim 1 ,

wherein the substrate has a first outer perimeter;

wherein the device has a second outer perimeter; and

wherein at least approximately 50% of the second outer perimeter of the device is disposed within approximately 1 mm from the first outer perimeter of the substrate.

10. The first product of claim 1 , wherein the first barrier film is deposited using chemical vapor deposition CVD and an organosilicon precursor.

11. The first product of claim 1 , wherein the first product comprises anyone of: a solar cell, a thin film battery, an organic electronic device, a lighting panel or a lighting source having a lighting panel, a display or an electronic device having a display, a mobile phone, a notebook computer, a tablet computer, a television, or an organic light emitting device (OLED).

12. The first product of claim 1 ,

wherein an electronics packaging comprises the first product, and

wherein the electronics packaging has a total area that is less than the total area of the device.

13. The first product of claim 1 , further comprising a plurality of devices, wherein each of the plurality of devices is disposed at a distance of less than 6 mm from at least one of the other devices.

14. The first product of claim 1 ,

wherein the substrate further comprises a second surface;

wherein a plurality of electrical conductors are disposed within the substrate; and

wherein each of the plurality of conductors extends from the first surface to the second surface of the substrate.

15. The first product of claim 1 ,

wherein a plurality of electrical conductors are disposed on the first side;

wherein the substrate further comprises a second surface; and

wherein each of the plurality of conductors extends from the first surface to the second surface of the substrate.
