Abstract

A method of manufacture of a circuit system includes: providing a carrier base; forming a cavity in the carrier base; forming a bridge lead over the cavity, the bridge lead exposing the cavity; and mounting a device having an anchor interconnect, the anchor interconnect is in the cavity and conformal to the bridge lead over the cavity.

Claims (49)

1. A method of manufacture of a circuit system comprising:

providing a carrier base;

forming a cavity in the carrier base;

forming a bridge lead over and completely across the cavity, a portion of the cavity exposed from the bridge lead; and

mounting a device having an anchor interconnect, the anchor interconnect filling the cavity and conformal to the bridge lead over the cavity.

2. The method as claimed in claim 1 wherein:

forming the cavity includes forming an interface pad in and conformal to the cavity; and

mounting the device includes mounting the device having the anchor interconnect connected to the interface pad.

3. The method as claimed in claim 1 wherein:

forming the cavity includes forming an interface pad in and conformal to the cavity; and

forming the bridge lead over the cavity includes connecting the bridge lead and the interface pad.

4. The method as claimed in claim 1 wherein mounting the device includes mounting the device having the anchor interconnect conformal to a gap of the bridge lead, the gap over the cavity.

5. The method as claimed in claim 1 wherein forming the cavity includes forming the cavity having a semi-spherical geometric shape.

6. A method of manufacture of a circuit system comprising:

providing a carrier base;

forming a cavity in the carrier base;

forming a bridge lead over and completely across the cavity, a portion of the cavity exposed from the bridge lead;

mounting a device having an anchor interconnect, the anchor interconnect filling the cavity and conformal to the bridge lead over the cavity; and

forming an encapsulation between the device and the carrier base and covering the anchor interconnect and the bridge lead.

7. The method as claimed in claim 6 further comprising:

forming a filler in the cavity; and

wherein:

forming the bridge lead over the cavity includes forming the bridge lead over the filler.

8. The method as claimed in claim 6 wherein mounting the device includes mounting the device having the anchor interconnect conformal to the cavity.

9. The method as claimed in claim 6 wherein forming the cavity includes forming the cavity having a cylindrical geometric shape.

10. The method as claimed in claim 6 wherein mounting the device includes mounting a flip chip.

11. A circuit system comprising:

a carrier having a cavity;

a bridge lead over and completely across the cavity, a portion of the cavity exposed from the bridge lead; and

a device having an anchoring interconnect over the carrier, the anchor interconnect filling the cavity and conformal to the bridge lead over the cavity.

12. The system as claimed in claim 11 further comprising:

an interface pad in and conformal to the cavity; and

wherein:

the anchor interconnect is connected to the interface pad.

13. The system as claimed in claim 11 further comprising:

an interface pad in and conformal to the cavity; and

wherein:

the bridge lead is connected to the interface pad.

14. The system as claimed in claim 11 wherein:

the bridge lead includes the bridge lead having a gap over the cavity; and

the anchor interconnect is conformal to and connects the gap of the bridge lead.

15. The system as claimed in claim 11 wherein the cavity has a semi-spherical geometric shape.

16. The system as claimed in claim 11 further comprising an encapsulation between the device and the carrier and covering the anchor interconnect and bridge lead.

17. The system as claimed in claim 16 wherein the anchor interconnect is conformal to the cavity.

18. The system as claimed in claim 16 wherein the cavity has a cylindrical geometric shape.

19. The system as claimed in claim 16 wherein:

the device includes a mounting pad; and

the anchor interconnect is connected to the mounting pad.

20. The system as claimed in claim 16 wherein the device includes a flip-chip.
