Abstract

A semiconductor chip package and a method of fabricating a semiconductor chip package provide a reduced chip size package. The semiconductor chip package includes a semiconductor chip; a plurality of pads disposed on an upper surface of the semiconductor chip; a thermosetting resin formed on the upper surface of the semiconductor chip such that through-holes in the thermosetting resin expose the pads; a multi-layer wiring pattern formed on the thermosetting resin; a connecting unit electrically connecting the multi-layer wiring pattern with the pads; a solder resist on the thermosetting resin and at least on of the multi-layer wiring pattern and the connecting unit, such that at least one through-hole in the solder resist exposes a portion of at least one of the multi-layer wiring pattern and the connecting unit; and a solder ball mounted on the through-hole of the solder resist in contact with the exposed portion of the at least one of the multi-wiring pattern and the connecting unit.
