Semiconductor device and method for fabricating semiconductor device

A semiconductor device fabricating method comprising:

• providing a transistor portion in a semiconductor substrate;
• providing a current sensing portion for detecting current flowing through the transistor portion;
• providing an emitter electrode set to an emitter potential of the transistor portion;
• providing a sense electrode electrically connected to the current sensing portion;
• providing a Zener diode electrically connected to the sense electrode;
• providing an emitter potential electrode that is set to the emitter potential and is electrically connected to the Zener diode such that the Zener diode is electrically connected between the emitter potential electrode and the sense electrode;
• arranging for the emitter potential electrode to surround the sense electrode;
• providing one or more of a gate pad and an anode pad between the emitter potential electrode and at least a portion of the emitter electrode;
• providing a well region of a second conductivity type that is provided in the semiconductor substrate and set to the emitter potential;
• providing an interlayer dielectric film between the emitter potential electrode and the well region;
• providing a contact hole in the interlayer dielectric film;
• and
• providing, in the contact hole, a contact portion that electrically connects the emitter potential electrode and the well region in order to set the emitter potential electrode to the emitter potential.
