Claim:
1. A semiconductor device comprising: a first MOS transistor of a first conductivity type including a first main electrode connected to a first potential and a second main electrode connected to a second potential; and a second MOS transistor of a second conductivity type including a first main electrode connected to a control electrode of said first MOS transistor and a second main electrode connected to said second potential, wherein said control electrode of said first MOS transistor and a control electrode of said second MOS transistor are connected in common, said first and second MOS transistors are formed on a common wide bandgap semiconductor substrate, in said first MOS transistor, a main current flows in a direction perpendicular to a main surface of said wide bandgap semiconductor substrate, and in said second MOS transistor, a main current flows in a direction parallel to the main surface of said wide bandgap semiconductor substrate.
