Abstract

A semiconductor package without a chip carrier includes an insulating structure having an opening; an electroplated die pad provided in the opening; a chip attached to the electroplated die pad by a thermally conductive adhesive; a plurality of electrical contacts formed around the electroplated die pad, wherein at least one of the electrical contacts is provided on a top surface of the insulating structure, and the chip is electrically connected to the electrical contacts; and an encapsulant for encapsulating the chip, the insulating structure and the electrical contacts, wherein bottom surfaces of the insulating structure, the electroplated die pad and the electrical contacts, except the at least one electrical contact provided on the top surface of the insulating structure, are exposed from the encapsulant and are flush with a bottom surface of the encapsulant. A fabrication method of the semiconductor package is also provided.
