Abstract

An integrated circuit package system that includes: providing a support structure including a device and an electrical contact adjacent thereto; providing a mold system having a cavity, a recess channel, a recess integrally connected to the recess channel, and a resilient member that cooperatively engages the recess channel and the recess; engaging the mold system and the support structure with the cavity over the device and the resilient member between the device and the electrical contact; and injecting encapsulation material into the cavity.

Claims (24)

1. An integrated circuit package system comprising:

a support structure;

a device mounted on the support structure; and

an encapsulant having an encapsulant rim, the encapsulant rim is a non-horizontal portion of the encapsulant in direct contact with the support structure and having a concave surface characteristic of being formed from an elastic resilient member pressed against the support structure.

2. The system as claimed in claim 1 wherein:

the encapsulant protects the device without obscuring an electrical contact formed adjacent thereto.

3. The system as claimed in claim 1 further comprising an inter-device structure affixed to the support structure for blocking disruptive fields.

4. The system as claimed in claim 1 wherein:

the support structure includes a printed wiring board, a flexible circuit substrate, or a leadframe.

5. The system as claimed in claim 1 wherein:

the device includes semiconductor chips and integrated circuit packages.

6. The system as claimed in claim 1 wherein:

the device includes a first package and a second package.

7. The system as claimed in claim 1 wherein:

the device includes a second package that is not coplanar with the support structure.

8. The system as claimed in claim 1 wherein:

the integrated circuit package system includes a fan-in package-on-package structure.

9. The system as claimed in claim 1 wherein:

the encapsulant protects the device without obscuring an electrical interconnect array formed on a substrate of a second package.

10. The system as claimed in claim 9 wherein:

the electrical interconnect array is a ball grid array.

11. The system as claimed in claim 9 further comprising:

an electrical interconnect formed over the electrical interconnect array.

12. The system as claimed in claim 1 further comprising an electrical contact adjacent to the device for electrically connecting additional components and packages formed over the device.
