Abstract

An integrated circuit package system comprising: forming a finger; forming a die pad adjacent the finger; applying a fill material around the finger and the die pad; forming a cavity in the finger and fill material; and attaching an integrated circuit die over the die pad adjacent the finger with the fill material.

Claims (36)

1. An integrated circuit package system comprising:

a finger;

a die pad adjacent the finger;

a fill material around the finger and the die pad;

a cavity in the finger and fill material; and

an integrated circuit die over the die pad adjacent the finger with the fill material.

2. The system as claimed in claim 1 wherein the finger, the fill material around the finger, and the die pad is a leadframe subassembly.

3. The system as claimed in claim 1 wherein the finger includes a recess for isolation.

4. The system as claimed in claim 1 wherein the cavity includes the cavity through a lead connector and partially through the fill material.

5. The system as claimed in claim 1 further comprising a terminal lead adjacent a perimeter of a leadframe subassembly.

6. The system as claimed in claim 1 further comprising a die connector connected to the integrated circuit die and the finger.

7. The system as claimed in claim 6 wherein the cavity is through more than one of a leadframe subassembly.

8. The system as claimed in claim 6 wherein the cavity includes characteristics of formation with a mask layer.

9. The system as claimed in claim 6 further comprising a tie bar attached to the die pad.

10. The system as claimed in claim 6 wherein the finger is an outer pad adjacent a perimeter of the die pad.

11. A method of manufacture of an integrated circuit package system comprising:

forming a finger;

forming a die pad adjacent the finger;

applying a fill material around the finger and the die pad;

forming a cavity in the finger and fill material; and

attaching an integrated circuit die over the die pad adjacent the finger with the fill material.

12. The method as claimed in claim 11 wherein applying the fill material around the finger and the die pad includes forming a leadframe subassembly.

13. The method as claimed in claim 11 wherein forming the finger includes forming a recess for isolation.

14. The method as claimed in claim 11 wherein forming the cavity includes forming the cavity through a lead connector and partially through the fill material.

15. The method as claimed in claim 11 further comprising forming a terminal lead adjacent a perimeter of a leadframe subassembly.

16. A method of manufacture of an integrated circuit package system comprising:

forming a finger;

forming a die pad adjacent the finger;

applying a fill material around the finger and the die pad;

forming a cavity in the finger and fill material;

attaching an integrated circuit die over the die pad adjacent the finger with the fill material; and

attaching a die connector to the integrated circuit die and the finger.

17. The method as claimed in claim 16 wherein forming the cavity includes forming the cavity through more than one of a leadframe subassembly.

18. The method as claimed in claim 16 wherein forming the cavity includes forming the cavity with a mask layer.

19. The method as claimed in claim 16 wherein forming the die pad includes attaching a tie bar to the die pad.

20. The method as claimed in claim 16 wherein forming the finger includes forming an outer pad adjacent a perimeter of the die pad.
