Abstract:
A method of manufacturing a semiconductor device includes forming a first trench and a second trench on a surface of a semiconductor substrate, the second trench being narrower than the first trench; forming an emitter connecting part and a trench gate that are separated from each other in the first trench and forming an embedded electrode in the second trench; forming a center insulating film in the first trench between the emitter connecting part and the trench gate; forming an interlayer insulating layer on the semiconductor substrate; forming a contact hole in the interlayer film at a location corresponding to the second trench; and forming an electrode material on the insulating layer so as to connect the electrode material and the embedded electrode in the second trench via the contact hole.

Claim (Index 2):
The method of manufacturing the semiconductor device according to  claim 1 ,\n wherein the second trench is provided in a plurality, and the plurality of the second trenches include an emitter contact trench that has an embedded emitter electrode electrically connected to the emitter connecting part, and a gate contact trench that has an embedded gate electrode electrically connected to the trench gate, wherein the forming of the contact hole includes forming a gate contact hole at a location corresponding to the gate contact trench, and forming an emitter contact hole at a location corresponding to the emitter contact trench, and wherein the forming of the electrode material includes forming a gate electrode and an emitter electrode on the insulating layer, the gate electrode and the embedded gate electrode in the gate contact trench are connected via the gate contact hole, and the emitter electrode and the embedded emitter electrode in the emitter contact trench are connected via the emitter contact hole, respectively.
