Abstract

An integrated circuit package system including an integrated circuit die and a lead frame with a trenched die pad. The integrated circuit die is mounted to the trenched die pad.

Claims (31)

1. An integrated circuit package system comprising:

providing an integrated circuit die;

forming a lead frame, the lead frame having a trenched die pad to restrain adhesive propagation, the trenched die pad having an adhesive trench with a channel-like formation, open to the outside; and

mounting the integrated circuit die to overhang edges of the trenched die pad.

2. The system as claimed in claim 1 wherein forming the lead frame having the trenched die pad comprises forming an adhesive plane.

3. The system as claimed in claim 1 wherein forming the lead frame comprises etching or machine stamping.

4. The system as claimed in claim 1 wherein mounting the integrated circuit die to the trenched die pad comprises applying an adhesive whereon the integrated circuit die and the trenched die pad are bonded.

5. The system as claimed in claim 1 further comprising electrically connecting the integrated circuit die to leads of the lead frame having the trenched die pad.

6. An integrated circuit package system comprising: providing an integrated circuit die; forming a lead frame, the lead frame having leads and a trenched die pad with an

adhesive trench and an adhesive plane to restrain adhesive

propagation, the trenched die pad having an adhesive trench with a channel-like formation, open to the outside; and mounting the integrated circuit die to the adhesive plane with the integrated

circuit die overhanging edges of the trenched die pad and the leads.

7. The system as claimed in claim 6 wherein forming the lead frame comprises forming leads in a dual row configuration and forming the adhesive trench within an outer dimension of the trenched die pad.

8. The system as claimed in claim 6 wherein forming the lead frame comprises forming leads in a dual row configuration and forming the adhesive trench at an outer dimension of the trenched die pad.

9. The system as claimed in claim 6 wherein forming the lead frame comprises forming leads in a single row configuration and forming the adhesive trench at the outer dimension of the trenched die pad.

10. The system as claimed in claim 6 wherein forming the lead frame comprises forming leads in a single row configuration and forming the adhesive trench within the outer dimension of the trenched die pad.

11. An integrated circuit package system comprising:

an integrated circuit die; and

a trenched die pad to restrain adhesive propagation, the trenched die pad having an adhesive trench with a channel-like formation, open to the outside wherein the integrated circuit die is mounted to the trenched die pad to extend over the trenched die pad.

12. The system as claimed in claim 11 wherein the lead frame having the trenched die pad comprises an adhesive plane.

13. The system as claimed in claim 11 wherein the lead frame having the trenched die pad comprises processes such as etching or machine stamping.

14. The system as claimed in claim 11 wherein the integrated circuit die mounted to the trenched die pad comprises an adhesive applied to the integrated circuit die attached to the trenched die pad.

15. The system as claimed in claim 11 further comprising the integrated circuit die electrically connected to leads of the lead frame.

16. An integrated circuit package system comprising:

an integrated circuit die;

a trenched die pad with an adhesive trench and an adhesive plane to restrain adhesive propagation, the trenched die pad having an adhesive trench with a channel-like formation, open to the outside; and

leads adjacent the trenched die pad wherein the integrated circuit die is mounted to the adhesive plane with the integrated circuit die overhanging edges of the trenched die pad and the leads.

17. The system as claimed in claim 16 wherein the lead frame comprises leads in a dual row configuration and the adhesive trench within an outer dimension of the trenched die pad.

18. The system as claimed in claim 16 wherein the lead frame comprises leads in the dual row configuration and the adhesive trench at the outer dimension of the trenched die pad.

19. The system as claimed in claim 16 wherein the lead frame comprises leads in a single row configuration and the adhesive trench at the outer dimension of the trenched die pad.

20. The system as claimed in claim 16 wherein the lead frame comprises leads in a single row configuration and the adhesive trench within the outer dimension of the trenched die pad.
