Accordingly, the semiconductor package becomes very thin and its heat spreading performance is improved.

A circuit board for semiconductor package is designed to provide a complete grounding with corresponding equipment in the manufacture of the semiconductor package based on a circuit board, thereby preventing a breakdown of the circuit board or semiconductor chip caused by electrostatic charges. The printed circuit board for semiconductor package includes: a resinous substrate; a chip mounting region formed on the top surface of the resinous substrate for mounting a semiconductor chip thereon; a plurality of fine circuit patterns radially disposed in the circumference of the chip mounting region and extending to the edge of the chip mounting region; a plurality of ball lands formed in an array on the bottom surface of the resinous substrate, to be fused to conductive balls; a conductive via hole connecting the circuit patterns on the top surface of the resinous substrate to the ball lands on the bottom surface of the resinous substrate; a cover coat applied to the top and bottom surfaces of the resinous substrate to protect the circuit patterns from an external environment and make the ball lands open to the exterior; and a means for removing electrostatic charges provided at the edge of the substrate and connected to the plural circuit patterns to remove electrostatic charges in the manufacture of semiconductors.
