Abstract

An integrated circuit package system includes: providing a substrate; forming a conductive layer over the substrate; forming a mold gate layer having an organic material without polymerization over the conductive layer; and attaching an integrated circuit over the substrate adjacent the mold gate layer.

Claims (36)

1. A method for manufacturing an integrated circuit package system comprising:

providing a substrate;

forming a conductive layer over the substrate;

forming a mold gate layer having an organic material without polymerization in direct contact with a top surface of the conductive layer;

attaching an integrated circuit over the substrate adjacent the mold gate layer; and

forming an encapsulant over the integrated circuit, the conductive layer, and the mold gate layer, a portion of a top surface of the mold gate layer exposed from the encapsulant.

2. The method as claimed in claim 1 wherein forming the mold gate layer includes forming an organic material having a hydrogen bond between hydrogen and nitrogen.

3. The method as claimed in claim 1 wherein forming the conductive layer includes forming copper.

4. The method as claimed in claim 1 wherein forming the mold gate layer includes forming the mold gate layer having a melting point predetermined for stability of the mold gate layer.

5. The method as claimed in claim 1 further comprising:

applying a separation process to the encapsulant.

6. A method for manufacturing an integrated circuit package system comprising:

providing a substrate;

forming a conductive layer over the substrate;

forming a mold gate layer having an organic material without polymerization in direct contact with a top surface of the conductive layer;

attaching an integrated circuit over the substrate adjacent the mold gate layer; and

applying an encapsulant over the integrated circuit, the conductive layer, and the mold gate layer, a portion of a top surface of the mold gate layer exposed from the encapsulant.

7. The method as claimed in claim 6 wherein forming the mold gate layer includes forming an imidazole over the conductive layer.

8. The method as claimed in claim 6 wherein forming the mold gate layer includes forming a copper organic surface protectant.

9. The method as claimed in claim 6 wherein forming the mold gate layer includes forming the mold gate layer having a melting point higher than two hundred fifty degrees Celsius.

10. The method as claimed in claim 6 further comprising applying a separation process including degating to the encapsulant.

11. An integrated circuit package system comprising:

a substrate;

a conductive layer over the substrate;

a mold gate layer having an organic material without polymerization in direct contact with a top surfaces of the conductive layer;

an integrated circuit over the substrate adjacent the mold gate layer; and

an encapsulant over the integrated circuit, the conductive layer, and the mold gate layer, a portion of a top surface of the mold gate layer exposed from the encapsulant.

12. The system as claimed in claim 11 wherein the mold gate layer is an organic material having a hydrogen bond between hydrogen and nitrogen.

13. The system as claimed in claim 11 wherein the conductive layer is copper.

14. The system as claimed in claim 11 wherein the mold gate layer has a melting point predetermined for stability of the mold gate layer.

15. The system as claimed in claim 11 wherein the encapsulant is separated.

16. The system as claimed in claim 11 wherein a portion of the substrate is exposed from the encapsulant.

17. The system as claimed in claim 16 wherein the mold gate layer is an imidazole over the conductive layer.

18. The system as claimed in claim 16 wherein the mold gate layer over the conductive layer is a copper organic surface protectant.

19. The system as claimed in claim 16 wherein the mold gate layer has a melting point higher than two hundred fifty degrees Celsius.

20. The system as claimed in claim 16 wherein the encapsulant includes an encapsulant protrusion on a first side of the encapsulant perpendicular to a second side of the encapsulant with the mold gate layer exposed from the encapsulant.
