Abstract:
A diode includes a first-conductivity-type barrier region disposed between a drift region and a second impurity region and having an impurity concentration higher than that of the drift region and a second-conductivity-type field extension prevention region disposed between the barrier region and the drift region. The diode also includes a trench gate disposed to extend from a second main surface of a semiconductor substrate through the second impurity region and the barrier region and reach the field extension prevention region. The trench gate has a gate electrode for applying a gate voltage. A gate electrode is applied with a parasitic gate voltage, as the gate voltage. The parasitic gate voltage has an absolute value of a potential difference with a second electrode being equal to or greater than a threshold voltage of a parasitic transistor formed of the second impurity region, the barrier region, and the field extension prevention region.

Claim (Index 8):
The semiconductor device according to  claim 3 ,\n wherein the drive unit applies the parasitic gate voltage as the gate voltage on condition that a power source voltage supplied to the reverse conducting switching element is a predetermined threshold or less.
