Abstract

Implementations of a packaging system may include a wafer; and a curvature adjustment structure coupled thereto where the curvature adjustment structure may be configured to alter a curvature of a largest planar surface of the wafer.

Claims (29)

1. A packaging system comprising:

a wafer; and

a curvature adjustment structure permanently coupled thereto;

wherein the curvature adjustment structure is configured to induce a curvature of a largest planar surface of the wafer.

2. The packaging system of claim 1 , wherein the curvature adjustment structure comprises a wheel and spoke structure.

3. The packaging system of claim 2 , wherein the wheel and spoke structure comprises at least two spokes.

4. The packaging system of claim 1 , wherein the curvature adjustment structure comprises two or more strips coupled across the largest planar surface of the wafer.

5. The packaging system of claim 1 , wherein the curvature adjustment structure comprises two or more intersecting strips comprised on the largest planar surface of the wafer.

6. The packaging system of claim 1 , wherein at least a portion of the curvature adjustment structure is positioned on an edge of the largest planar surface of the wafer.

7. The packaging system of claim 1 , wherein at least a portion of the curvature adjustment structure is comprised on an interior surface of the largest planar surface of the wafer.

8. A packaging system comprising:

a wafer; and

an organic material permanently bonded to a largest planar surface of the wafer;

wherein the organic material is configured to increase a curvature of the largest planar surface of the wafer.

9. The packaging system of claim 8 , wherein the organic material comprises a wheel and spoke structure.

10. The packaging system of claim 9 , wherein the wheel and spoke structure comprises at least two spokes.

11. The packaging system of claim 8 , wherein the organic material comprises two or more strips coupled across the largest planar surface of the wafer.

12. The packaging system of claim 8 , wherein the organic material comprises two or more intersecting strips comprised on the largest planar surface of the wafer.

13. The packaging system of claim 8 , wherein at least a portion of the organic material is positioned on an edge of the largest planar surface of the wafer.

14. The packaging system of claim 8 , wherein at least a portion of the organic material is comprised on an interior surface of the largest planar surface of the wafer.

15. A packaging system comprising:

a wafer; and

an organic material permanently bonded to a largest planar surface of the wafer;

wherein the organic material is configured to deflect at least a portion of the largest planar surface of the wafer and increase curvature in the largest planar surface of the wafer.

16. The packaging system of claim 15 , wherein the organic material comprises a wheel and spoke structure.

17. The packaging system of claim 15 , wherein the organic material comprises two or more strips coupled across the largest planar surface of the wafer.

18. The packaging system of claim 15 , wherein the organic material comprises two or more intersecting strips comprised on the largest planar surface of the wafer.

19. The packaging system of claim 15 , wherein at least a portion of the organic material is positioned on an edge of the largest planar surface of the wafer.

20. The packaging system of claim 15 , wherein at least a portion of the organic material is comprised on an interior surface of the largest planar surface of the wafer.
