An insulated gate bipolar transistor (IGBT) includes a gate trench, an emitter trench, and an electrically insulative layer coupled to the emitter trench and the gate trench and electrically isolating the gate trench from an electrically conductive layer. A contact opening in the electrically insulative layer extends into the emitter trench and the electrically conductive layer electrically couples with the emitter trench therethrough. A P surface doped (PSD) region and an N surface doped (NSD) region are each located between the electrically conductive layer and a plurality of semiconductor layers of the IGBT and between the gate trench and the emitter trench. The electrically conductive layer electrically couples to the plurality of semiconductor layers through the PSD region and/or the NSD region.
