  • Publication number: 20120001328
    Abstract: A chip-sized package and a fabrication method thereof are provided. The method includes forming a protection layer on an active surface of a chip and attaching a non-active surface of the chip to a carrier made of a hard material; performing a molding process and removing a protection layer from the chip; performing an RDL process to prevent problems as encountered in the prior art, such as softening of adhesive films, an encapsulant overflow, a pliable chip and chip deviation or contamination caused by directly adhering the active surface of the chip to the adhesive film that may even lead to inferior electrical contacts between a circuit layer and a plurality of chip bond pads during subsequent RDL process, and cause the package to be scraped. Further, the carrier employed in this invention can be repetitively used in the process to help reduce manufacturing costs.
