Abstract
A single semiconductor power module includes a power semiconductor chip including an embedded IGBT (the power semiconductor switching-device) and a control semiconductor chip. The power semiconductor chip also includes a gate series resistor integrated therein as a resistor through which the control semiconductor chip drives the power semiconductor chip. In such a configuration, a gate wire between the gate series resistor and a gate has a small lead inductance and a small parasitic capacitance with respect to the ground.
