Patent ID: 7410836

Claim:
A method for fabricating a photosensitive semiconductor package, comprising the steps of: preparing a lead frame having a die pad and a plurality of leads; forming at least one recessed portion at an end of each of the leads close to the die pad, and forming at least one recessed region on the die pad, wherein the at least one recessed region has a depth less than a thickness of the lead frame; performing a molding process to fabricate an encapsulant, which fills the recessed region of the die pad, the recessed portions of the leads and between the die pad and the leads, and is formed on the lead frame to define a chip receiving cavity; mounting a photosensitive chip in the chip receiving cavity, the chip having an active surface and a non-active surface, wherein at least partially the non-active surface of the chip is attached to the encapsulant formed in the recessed region of the die pad and is free of contact with the recessed region; electrically connecting the active surface of the chip to the plurality of leads via a plurality of bonding wires; and mounting a light-penetrable unit on the encapsulant formed on the lead frame to seal the chip receiving cavity.
