Abstract
A chip packaging process is provided. First, a cavity is formed on a heat sink. A first encapsulant is formed on the bottom of the cavity. A circuit substrate is disposed over the heat sink. The circuit substrate has an opening that corresponds in position to the cavity. Thereafter, a chip is disposed on the first encapsulant and the chip is electrically connected to the circuit substrate. Finally, a compound is deposited over the first encapsulant and the chip to form a chip package. The chip package is warp resistant and the chip packaging process increases overall production yield.
