Abstract

An integrated circuit package system includes an integrated circuit, and forming a patterned redistribution pad over the integrated circuit.

Claims (33)

1. An integrated circuit package system comprising:

providing an integrated circuit;

forming a patterned redistribution pad over the integrated circuit, the patterned redistribution pad including patterned redistribution pad openings along a perimeter of and through the patterned redistribution pad wherein the pattern redistribution pad is conductive: and

filling the patterned redistribution pad openings with a solid material wherein the solid material is conductive.

2. The system as claimed in claim 1 wherein filling the patterned redistribution pad openings with the solid material includes filling at least one patterned redistribution pad opening with a conductive material.

3. The system as claimed in claim 1 wherein forming the patterned redistribution pad includes forming a patterned redistribution pad center opening.

4. The system as claimed in claim 1 further comprising forming an insulating layer opening over the patterned redistribution pad.

5. The system as claimed in claim 1 further comprising forming an insulating layer island over the patterned redistribution pad.

6. An integrated circuit package system comprising:

providing an integrated circuit wafer;

forming a redistribution layer over the integrated circuit wafer having a redistribution trace and a patterned redistribution pad, the patterned redistribution pad including patterned redistribution pad openings along a perimeter of and through the patterned redistribution pad wherein the pattern redistribution pad is conductive:

filling the patterned redistribution pad openings with a solid material wherein the solid material is conductive; and

applying an under bump layer over the patterned redistribution pad.

7. The system as claimed in claim 6 wherein forming the redistribution layer includes forming patterned redistribution pad openings in a shape of an oval.

8. The system as claimed in claim 6 wherein forming the redistribution layer includes forming patterned redistribution pad openings with the patterned redistribution pad having a shape of a spoke.

9. The system as claimed in claim 6 wherein forming the redistribution layer includes forming patterned redistribution pad openings in a shape of a polygon.

10. The system as claimed in claim 6 wherein forming the redistribution layer includes forming patterned redistribution pad openings in a shape of a trench.

11. An integrated circuit package system comprising:

an integrated circuit; and

a patterned redistribution pad over the integrated circuit, the patterned redistribution pad including patterned redistribution pad openings along a perimeter of and through the patterned redistribution pad wherein the pattern redistribution pad is conductive and the patterned redistribution pad openings filled with a solid material wherein the solid material is conductive.

12. The system as claimed in claim 11 wherein at least one patterned redistribution pad opening is filled with a conductive material.

13. The system as claimed in claim 11 wherein the patterned redistribution pad includes a patterned redistribution pad center opening.

14. The system as claimed in claim 11 further comprising an insulating layer opening over the patterned redistribution pad.

15. The system as claimed in claim 11 further comprising an insulating layer island over the patterned redistribution pad.

16. The system as claimed in claim 11 wherein:

the integrated circuit is an integrated circuit wafer;

the patterned redistribution pad is a redistribution layer having the patterned redistribution pad and a redistribution trace over the integrated circuit wafer; and

further comprising:

an under bump layer over the patterned redistribution pad.

17. The system as claimed in claim 16 wherein the redistribution layer includes patterned redistribution pad openings in a shape of an oval.

18. The system as claimed in claim 16 wherein the redistribution layer includes patterned redistribution pad openings with the patterned redistribution pad having a shape of a spoke.

19. The system as claimed in claim 16 wherein the redistribution layer includes patterned redistribution pad openings in a shape of a polygon.

20. The system as claimed in claim 16 wherein the redistribution layer includes patterned redistribution pad openings in a shape of a trench.
