Abstract:
An insulated gate bipolar transistor and a method for fabricating the insulated gate bipolar transistor are provided. The insulated gate bipolar transistor includes a semiconductor layer including a bulk layer and a cell region including a first region and a second region. The insulated gate bipolar transistor also includes a well region, a drift region, and a plurality of gate structures in the bulk layer associated with the cell region. Further, the insulated gate bipolar transistor includes source and drain doped regions and an ohmic contact region in a top region of the well region. A size of the source and drain doped regions in the second region is smaller than a size of the source and drain doped regions in the first region. A size of the ohmic contact region in the second region is larger than a size of the ohmic contact region in the first region.

Claim (Index 4):
The insulated gate bipolar transistor according to  claim 3 , wherein:\n the source and drain doped regions in the second region have a first maximum size; the ohmic contact region in the second region has a second maximum size; the size of the source and drain doped regions between the adjacent gate structures in the second region is the same along the direction from the cell region to the edge region; the reduced size of the source and drain doped regions on one side of the gate structure in the second region compared to the source and drain doped regions on the other side of the gate structure in the second region is in a range of approximately \u2153-\u2155 of the first maximum size along the direction from the cell region to the edge region; and the increased size of the adjacent ohmic contact regions in the second region is in a range of approximately \u2153-\u2155 of the second maximum size along the direction from the cell region to the edge region.
