Heat dissipating package structure and method for fabricating the same

A method for fabricating a heat dissipating package structure, comprising the steps of:

• mounting and electrically connecting a semiconductor chip to at least one chip carrier, providing a heat spreader having a hollow structure and attached to an interface layer, and mounting the heat spreader on the semiconductor chip, wherein the semiconductor chip is larger in size than the hollow structure of the heat spreader;
• performing a molding process to form an encapsulant for completely encapsulating the semiconductor chip on the chip carrier and the heat spreader with the interface layer;
• performing a singulation process to remove peripheral non-electrical functional portion of a package unit, such that sides of the heat spreader are exposed;
• and
• removing the interface layer and a part of the encapsulant formed on the interface layer so as to expose the heat spreader and allow a part of the semiconductor chip to be exposed to the hollow structure of the heat spreader.
