Abstract:
A semiconductor device comprising:a first conduction type semiconductor substrate in which a plurality of first conduction type semiconductor areas and a plurality of second conduction type semiconductor areas are alternately formed adjacent to each other;a first transistor having the second conduction type semiconductor areas as a source area and a drain area, with the first conduction type semiconductor area between them forming a channel section; anda second transistor having the first conduction type semiconductor areas as a source area and a drain area, with the second conduction type semiconductor area between them forming a channel section, the source or drain area of the second transistor being formed adjacent to the first transistor so as to serve as the channel section of the first transistor in a shared manner, one of the first and second transistors having a reversely biased coupling between the first and the second conduction type semiconductor areas while the other transistor is being operated.
