发明名称 Thin IC package for improving heat dissipation from chip backside
摘要 A thin IC package to enhance heat dissipation from the back surface of a chip, comprises a substrate, the chip, and an encapsulant where the substrate has an upper surface, a lower surface, and an opening to accommodate the chip. The chip is disposed in the opening of the substrate where the chip has an active surface, a back surface, and a plurality of bonding pads disposed on the active surface to electrically connect to the substrate. At least a slot is formed on the back surface of the chip. Preferably, a plurality of the slots on the back surface of the chip form a plurality of integral thermal fins therefrom. The encapsulant are formed on the upper surface of the substrate and in the opening to embed the chip with the back surface and the slots being exposed from the encapsulant to enhance the heat dissipation from the back surface of the chip and to enhance chip strength.
