Abstract

An integrated circuit package system is provided including providing a substrate having a die attached and electrically bonded thereto. The system includes forming heat slug pillars on the substrate, positioning a heat slug on the heat slug pillars, and encapsulating the substrate, the die, the heat slug pillars, and the heat slug in a mold compound. The system includes singulating the substrate, the die, the heat slug, and the mold compound.

Claims (20)

1. An integrated circuit package system comprising:

providing a substrate having a die attached and electrically bonded thereto;

forming heat slug pillars on the substrate;

positioning a heat slug on the heat slug pillars and including providing the heat slug with a groove around the periphery thereof inside the heat slug pillars when positioned;

encapsulating the substrate, the die, the heat slug pillars, and the heat slug in a mold compound; and

singulating the substrate, the die, the heat slug, and the mold compound to eliminate the heat slug pillars.

2. The system as claimed in claim 1 wherein positioning the heat slug on the heat slug pillars includes bonding the heat slug to the heat slug pillars.

3. The system as claimed in claim 1 wherein positioning the heat slug includes providing the heat slug with indentations provided therein for heat dissipation thereby.

4. The system as claimed in claim 1 wherein positioning the heat slug includes providing the heat slug with lines for individual heat slugs connected by tie bars.

5. An integrated circuit package system comprising:

providing a substrate having dies attached and electrical bonds thereto;

applying pillars of adhesive around the periphery of the substrate;

placing a heat slug on the pillars of adhesive;

molding the heat slug, the pillars of adhesive, the dies, and the substrate in a molding compound;

mounting solder balls on the substrate for electrically connecting to the dies; and

singulating the substrate, the mold compound, and the heat slug into integrated circuit packages without the pillars of adhesive.

6. The system as claimed in claim 5 wherein placing the heat slug places the heat slug above the dies and electrical bonds.

7. The system as claimed in claim 5 wherein placing the heat slug includes providing the heat slug with indentions provided therein.

8. The system as claimed in claim 5 wherein placing the heat slug includes providing the heat slug with a groove around the periphery thereof inside the heat slug pillars and out side the electrical bonds when positioned.

9. The system as claimed in claim 5 wherein placing the heat slug includes providing the heat slug with full-etched lines for individual heat slugs connected by tie bars.
