Patent ID: 8546937

Claim:
A semiconductor device comprising: a first die pad having a conductivity and electrically connected to one end of a power source to supply high potential power; a second die pad having a conductivity and electrically connected to another end of the power source to supply a low potential power; a first switching element provided on the first die pad, receiving the high potential power from the power source via the first die pad, and having a terminal connected to a first output terminal, the terminal being opposite to the first die pad; and a second switching element provided on the second die pad, receiving the low potential power from the power source via the second die pad, and having a terminal connected to the first output terminal, the terminal being opposite to the second die pad, wherein the first switching element includes a first main electrode which is formed on a side of the first die pad and receives the high potential power, a second main electrode which is formed at a position opposite to the first main electrode and is electrically connected to the first output terminal, the first switching element having a vertical structure in which a current flows vertically on the front surface of the first die pad; and the second switching element includes a substrate electrode which is formed on a side of the second die pad and receives the low potential power, a third main electrode which is formed at a position opposite to the substrate electrode and is electrically connected to the substrate electrode, and a fourth main electrode electrically connected to the first output terminal, the second switching element having a horizontal structure in which a current flows horizontally on the surface of the second die pad.
