Abstract: A transistor device includes an individual transistor cell arranged in a transistor cell field on a semiconductor body, the individual transistor cell having a gate electrode. The transistor device further includes a gate contact, electrically coupled to the gate electrode and configured to switch on the individual transistor cell by providing a gate current in a first direction and configured to switch off the individual transistor cell by providing a gate current in a second direction, the second direction being opposite to the first direction. The transistor device also includes a gate-resistor structure monolithically integrated in the transistor device. The gate-resistor structure provides a first resistance for the gate current when the gate current flows in the first direction, and provides a second resistance for the gate current, which is different from the first resistance, when the gate current flows in the second direction.

The semiconductor device further includes a drift or base zone in the first semiconductor region. The semiconductor device further includes an emitter region in the second semiconductor region. The second semiconductor region includes at least one type of deep-level dopant. A solubility of the at least one type of deep-level dopant is higher in the second semiconductor region than in the first semiconductor region.
