Abstract

An integrated circuit package system is provided including forming an external interconnect, providing a contoured integrated circuit die having both an extension and a base portion with the extension extending beyond the base portion, placing the contoured integrated circuit die with the base portion coplanar with the external interconnect and the extension overhanging the external interconnect, connecting the contoured integrated circuit die and the external interconnect, and forming a package encapsulation over the contoured integrated circuit die and the external interconnect with both partially exposed.

Claims (63)

1. An integrated circuit package system comprising:

forming an external interconnect;

providing a contoured integrated circuit die having both an extension and a base portion with the extension extending beyond the base portion;

placing the contoured integrated circuit die with the base portion coplanar with the external interconnect and the extension overhanging the external interconnect;

connecting the contoured integrated circuit die and the external interconnect; and

forming a package encapsulation over the contoured integrated circuit die and the external interconnect with both partially exposed, the package encapsulation between the overhanging portion of the extension and facing portions of the external interconnect.

2. The system as claimed in claim 1 wherein providing the contoured integrated circuit die having both the extension and the base portion includes partially cutting a non-active side of the contoured integrated circuit die to create the base portion and the extension.

3. The system as claimed in claim 1 wherein:

providing the contoured integrated circuit die having both the extension and the base portion includes:

forming the base portion from a non-active side of the contoured integrated circuit die with the extension along an active side of the contoured integrated circuit die; and

forming the package encapsulation further includes:

exposing the non-active side.

4. The system as claimed in claim 1 wherein:

providing the contoured integrated circuit die having both the extension and the base portion includes:

forming the base portion from a non-active side of the contoured integrated circuit die with the extension along an active side of the contoured integrated circuit die;

forming a backside concealer on the non-active side; and

forming the package encapsulation includes:

exposing the backside concealer.

5. The system as claimed in claim 1 wherein forming the package encapsulation includes supporting the extension without a separate support structure.

6. An integrated circuit package system comprising:

forming an external interconnect having a bottom side and a top side;

providing a contoured integrated circuit die includes:

providing a non-active side and an active side,

providing an extension along the active side, and

providing a base portion along the non-active side with the extension extending beyond the base portion;

placing the contoured integrated circuit die with the base portion coplanar with the bottom side and the extension overhanging the top side;

connecting the contoured integrated circuit die and the external interconnect; and

forming a package encapsulation over the contoured integrated circuit die and the external interconnect with both partially exposed, the package encapsulation between the overhanging portion of the extension and facing portions of the external interconnect.

7. The system as claimed in claim 6 wherein providing the contoured integrated circuit die includes forming an edge of the contoured integrated circuit die in a stepped configuration.

8. The system as claimed in claim 6 wherein placing the contoured integrated circuit die includes placing the non-active side coplanar with the bottom side.

9. The system as claimed in claim 6 wherein forming the package encapsulation includes exposing the base portion of the non-active side.

10. The system as claimed in claim 6 wherein forming the package encapsulation includes exposing the bottom side.

11. An integrated circuit package system comprising:

an external interconnect;

a contoured integrated circuit die having both an extension and a base portion with the extension extending beyond the base portion with the base portion coplanar with the external interconnect and the extension overhanging the external interconnect;

an internal interconnect between the contoured integrated circuit die and the external interconnect; and

a package encapsulation over the contoured integrated circuit die and the external interconnect with both partially exposed, the package encapsulation between the overhanging portion of the extension and facing portions of the external interconnect.

12. The system as claimed in claim 11 wherein the contoured integrated circuit die includes a non-active side of the contoured integrated circuit die partially cut to create the base portion and the extension.

13. The system as claimed in claim 11 wherein:

the contoured integrated circuit die having both the extension and the base portion includes:

the base portion in a non-active side of the contoured integrated circuit die;

the extension along an active side of the contoured integrated circuit die; and

the package encapsulation further includes:

the non-active side exposed.

14. The system as claimed in claim 11 wherein:

the contoured integrated circuit die having both the extension and the base portion includes:

the base portion in a non-active side of the contoured integrated circuit die;

the extension along an active side of the contoured integrated circuit die;

a backside concealer on the non-active side; and

the package encapsulation includes:

the backside concealer exposed.

15. The system as claimed in claim 11 wherein the package encapsulation is between the extension and the external interconnect below the extension without a separate support structure.

16. The system as claimed in claim 11 wherein:

the external interconnect has a bottom side and a top side;

the contoured integrated circuit die has a non-active side and an active side includes:

the extension along the active side, and

the base portion along the non-active side with the extension extending beyond the base portion;

the internal interconnect is a wire; and

the package encapsulation exposes the non-active side and the bottom side.

17. The system as claimed in claim 16 wherein the contoured integrated circuit die includes an edge of the contoured integrated circuit die in a stepped configuration.

18. The system as claimed in claim 16 wherein the contoured integrated circuit die includes the non-active side coplanar with the bottom side.

19. The system as claimed in claim 16 wherein the package encapsulation exposes the base portion of the non-active side.

20. The system as claimed in claim 16 wherein the package encapsulation exposes the bottom side.
