A semiconductor device that does not include a molded body or package. The semiconductor
device includes a substrate and a die coupled to the substrate. The die is coupled
to the substrate such that the source and gate regions of the die, assuming a MOSFET-type
device, are coupled to the substrate. Solder balls are provided adjacent to the
die such that when the semiconductor device is coupled to a printed circuit board,
the exposed surface of the die serves as a drain connection while the solder balls
serve as the source and gate connections.
