Abstract
Provided is a semiconductor package accomplishing a fan-out structure through wire bonding in which a pad of a semiconductor chip is connected to a printed circuit board through wire bonding. A semiconductor package can be produced without a molding process and can be easily stacked on another semiconductor package while the appearance cracks and the warpage defects can be prevented.
Claims10
A semiconductor package comprising:
- a first semiconductor chip including a plurality of first solder ball pads and a plurality of first bond fingers formed on a first surface;
- a first multi-layered printed circuit board including:
- a plurality of second bond fingers and a plurality of second solder ball pads formed on a first surface,
- a chip recess configured to receive the semiconductor chip, and
- a plurality of third solder ball pads formed on a second surface,
- wherein the plurality of second bond fingers and the plurality of second solder ball pads are distributed about portions of the periphery of the chip recess,
- wherein the plurality of first bond pads and the plurality of second bond pads correspond in position to one another when the semiconductor chip is located in the chip recess;
- a plurality of wires to connect the first bond fingers and the second bond fingers;
- an encapsulant to seal the plurality of wires;
- and
- a first plurality of solder balls attached to the first plurality of solder ball pads and to the plurality of second solder ball pads.
