<p>A control device of a semiconductor device is provided. The control device of a semiconductor device is capable of reducing both ON resistance and feedback capacitance in a hollow-gate type planar MOSFET to which a second gate electrode is provided or a trench MOSFET to which a second gate electrode is provided. In the control device controlling driving of a hollow-gate type planar MOSFET to which a second gate electrode is provided or a trench MOSFET to which a second gate electrode is provided, a signal of tuning ON or OFF is outputted to a gate electrode in a state of outputting a signal of turning OFF to the second gate electrode.</p> |
