Patent ID: 7371617

Claim:
A method for fabricating a semiconductor package with a heat sink, comprising the steps of: mounting a detach member, a heat sink and a chip on a chip carrier, wherein the heat sink is disposed between the detach member and the chip, and the chip is disposed between the heat sink and the chip carrier, and wherein the detach member is sized larger than the heat sink and is removable from the heat sink; forming an encapsulant on the chip carrier to completely encapsulate the detach member, the heat sink and the chip; cutting along predetermined cutting lines located between sides of the detach member and corresponding sides of the heat sink so as to remove portions of the detach member, the encapsulant and the chip carrier that are located outside the predetermined cutting lines; and separating the detach member and a portion of the encapsulant formed on the detach member from the heat sink and the rest of the encapsulant, such that a top surface of the heat sink is exposed to the atmosphere.
