Abstract
An adjacent active trench in an IGBT region and an adjacent capacitance adjustment trench in a diode region are each provided in a stripe shape extending in a Y direction in a plan view. Each of a plurality of crossing trenches extends in an X direction orthogonal to the Y direction in a plan view and is provided in a stripe shape. Each of the plurality of crossing trenches is provided from the adjacent capacitance adjustment trench to the adjacent active trench in a plan view. Therefore, the gate electrode of the adjacent active trench and the capacitance adjustment electrode of the adjacent capacitance adjustment trench are electrically connected via the electrode for the crossing trench in the crossing trench.
