Abstract

An integrated circuit package system comprising: forming a paddle having a hole and an external interconnect; mounting an integrated circuit device having an active side to the paddle with the active side facing the paddle and the hole; connecting a first internal interconnect between the active side and the external interconnect through the hole; and encapsulating the integrated circuit device, the paddle, the first internal interconnect, and the external interconnect with the external interconnect partially exposed.

Claims (41)

1. A method of manufacturing an integrated circuit package comprising:

forming a paddle having four edge bars and a central cross bar resulting in the formation of two adjacent holes, wherein a first hole and a second hole are separated by the central cross bar and surrounded by the four edge bars;

forming a first external interconnect adjacent to the first hole;

forming a second external interconnect adjacent to the second hole;

mounting a first integrated circuit die to the paddle and the central cross bar, the first integrated circuit die having a first active side facing the first hole, wherein an edge of the first integrated circuit die aligns with a first outside edge of at least one of the four edge bars;

mounting a second integrated circuit die to the paddle and the central cross bar, the second integrated circuit die having a second active side facing the second hole, wherein an edge of the second integrated circuit die aligns with a second outside edge of at least one of the four edge bars;

connecting the first active side and the first external interconnect with a first internal interconnect through the first hole;

connecting the second active side and the second external interconnect with a second internal interconnect through the second hole; and

encapsulating the first integrated circuit die, the second integrated circuit die, the paddle, the first internal interconnect, the second internal interconnect, the first external interconnect, and the second external interconnect with an encapsulation leaving a portion of the bottom surfaces of the first integrated circuit die, the second integrated circuit die, the first external interconnect, and the second external interconnect partially exposed.

2. The method as claimed in claim 1

further comprising:

mounting an integrated circuit device structure over the encapsulation;

connecting the integrated circuit device structure and the at least one of the first external interconnect and the second external interconnect with a third internal interconnect; and

forming a package encapsulation cover over the integrated circuit device structure, the encapsulation, and the third internal interconnect with a portion of the at least one of the first external interconnect and the second external interconnect partially exposed.

3. A method of manufacturing an integrated circuit package comprising:

forming a paddle having four edge bars and a central cross bar resulting in the formation of two adjacent holes, wherein a first hole and a second hole are separated by the central cross bar and surrounded by the four edge bars;

forming a first external interconnect adjacent to the first hole, the first external interconnect having a first body and a first tip, wherein the first tip and the first hole are elevated above the first body;

forming a second external interconnect adjacent to the second hole, the second external interconnect having a second body and a second tip, wherein the second tip and the second hole are elevated above the second body;

mounting a first integrated circuit die to the paddle and the central cross bar with a first adhesive, the first integrated circuit die having a first active side facing the first hole, wherein an edge of the first integrated circuit die aligns with a first outside edge of at least one of the four edge bars;

mounting a second integrated circuit die to the paddle and the central cross bar with a second adhesive, the second integrated circuit die having a second active side facing the second hole, wherein an edge of the second integrated circuit die aligns with a second outside edge of at least one of the four edge bars;

connecting the first active side of the first integrated circuit die and the first external interconnect with a first internal interconnect through the first hole;

connecting the second active side of the second integrated circuit die and the second external interconnect with a second internal interconnect through the second hole; and

encapsulating the first integrated circuit die, the second integrated circuit die, the paddle, the first internal interconnect, the second internal interconnect, the first external interconnect, and the second external interconnect with an encapsulation leaving a portion of the bottom surfaces of the first integrated circuit die, the second integrated circuit die, the first external interconnect, and the second external interconnect partially exposed.

4. An integrated circuit package system comprising:

a paddle having four edge bars and a central cross bar configured to form two adjacent holes, wherein a first hole and a second hole are separated by the central cross bar and surrounded by the four edge bars;

a first external interconnect adjacent the first hole of the paddle

a second external interconnect adjacent the second hole of the paddle;

a first integrated circuit die mounted to the paddle and the central cross bar, the first integrated circuit die having a first active side facing the first hole, wherein an edge of the first integrated circuit die is configured to be in alignment with a first outside edge of at least one of the four edge bars;

a second integrated circuit die mounted to the saddle and the central cross bar, the second integrated circuit die having a second active side facing the second hole, wherein an edge of the second integrated circuit die is configured to be in alignment with a second outside edge of at least one of the four edge bars;

a first internal interconnect between the first active side and the first external interconnect through the first hole;

a second internal interconnect between the second active side and the second external interconnect through the second hole; and

an encapsulation over the first integrated circuit die, the second integrated circuit die, the paddle, the first internal interconnect, the second internal interconnect, the first external interconnect, and the second external interconnect with a portion of the bottom surfaces of the first integrated circuit die, the second integrated circuit die, the first external interconnect and the second external interconnect partially exposed.

5. The system as claimed in claim 4 further comprising:

an integrated circuit device structure mounted over the encapsulation;

a third internal interconnect between a structure active side of the integrated circuit device structure and at least one of the first external interconnect and the second external interconnect; and

a package encapsulation cover over the integrated circuit device structure, the encapsulation, and the third internal interconnect, with a portion of the at least one of the first external interconnect and the second external interconnect partially exposed.

6. The system as claimed in claim 4 wherein:

the first external interconnect includes a first body and a first tip, wherein the first tip and the first hole are elevated above the first body;

the second external interconnect includes a second body and a second tip, wherein the second tip and the second hole are elevated above the second body;

the first integrated circuit die is mounted to the paddle and the central cross bar with a first adhesive; and

the second integrated circuit die is mounted to the paddle and the central cross bar with a second adhesive.
