Disclosed are a chip scale package and a method of fabricating the chip scale package. The chip scale package comprises conductive layers with a designated depth formed on an upper and a lower surfaces of a chip, and electrode surfaces formed on the same side surfaces of the conductive layers, which are connected to corresponding connection pads of a printed circuit board. The chip scale package is miniaturized in the whole package size. Further, the method of fabricating the chip scale package does not require a wire-bonding step or a via hole forming step, thereby simplifying the fabrication process of the chip scale package and improving the reliability of the chip scale package.

Chip scale package and method of fabricating the same

A chip scale package has an insulating layer formed on the upper surface of a chip provided with a plurality of terminals on its one surface, a plurality of conductive layers formed on the insulating layer and spaced from each other by a designated distance so as to be connected to each of a plurality of the terminals, and a plurality of electrode surface layers formed on each of the upper surfaces of a plurality of the conductive layers.

A method of fabricating a chip scale package includes: preparing a wafer including a plurality of chips; forming an insulating layer on the upper surface of the wafer except in areas of two upper terminals of each chip; forming an upper conductive layer on the insulating layer so as to be connected to the upper terminals of the chips; forming a lower conductive layer on the lower surface of the wafer so as to be connected to a lower terminals of each chip; first dicing the wafer so that one side of the chip scale package is formed; forming electrode surfaces on side surfaces of the upper and the lower conductive layers which are defined by the side of the chip scale package formed in the first dicing step; dividing the upper conductive layer of each chip into two areas each connected to one of the two upper terminals; and second dicing the wafer into package units.
