Abstract

An integrated circuit package system includes providing a substrate. An integrated circuit is attached to the substrate. A plurality of support bars is formed on the substrate. A plurality of adhesive structures is formed. A heat sink is attached to the plurality of adhesive structures. The integrated circuit is encapsulated. The support bars are removed.

Claims (24)

1. An integrated circuit package system comprising:

providing a substrate;

attaching an integrated circuit to the substrate;

forming a plurality of support bars on the substrate wherein forming the plurality of support bars on the substrate forms support bars having a height higher than the height of the integrated circuit;

forming a plurality of adhesive structures;

attaching a heat slug to the plurality of adhesive structures;

encapsulating the integrated circuit; and

removing the support bars.

2. The system for packaging integrated circuits as claimed in claim 1 , wherein forming a plurality of support bars on the substrate forms a plurality of adhesive dots.

3. The system for packaging integrated circuits as claimed in claim 1 , wherein:

forming a plurality of adhesive structures forms a plurality of adhesive dots on the plurality of support bars.

4. The system for packaging integrated circuits as claimed in claim 1 , wherein forming a plurality of adhesive structures forms a plurality of adhesive dots having a height higher than the height of the plurality of support bars.

5. An integrated circuit package system comprising:

providing a substrate;

attaching a plurality of integrated circuits to the substrate to form an array of integrated circuits;

forming a plurality of support bars around outer edges of the array of integrated circuits wherein forming the plurality of support bars on the substrate forms support bars having a height higher than the height of the array of integrated circuits;

forming a plurality of adhesive structures;

attaching a heat slug to the plurality of adhesive structures over the array of integrated circuits;

encapsulating the array of integrated circuits and the support bars to form an array of packaged integrated circuits; and

singulating the array of integrated circuits to form packaged integrated circuits having a heat sink above the integrated circuit above the array of integrated circuits and exposed through the encapsulant.

6. The system for packaging integrated circuits as claimed in claim 5 , wherein forming a plurality of support bars on the substrate forms a plurality of adhesive dots.

7. The system for packaging integrated circuits as claimed in claim 5 , wherein:

forming a plurality of adhesive structures forms a plurality of adhesive structures on the plurality of support bars.

8. The system for packaging integrated circuits as claimed in claim 5 , wherein forming a plurality of adhesive structures forms a plurality of adhesive dots having a height higher than the height of the plurality of support bars.
