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 20):
The method according to  claim 10 , wherein:\n the edge region includes a transition region and a terminal protection region adjacent to the transition region; and the transition region is located between the cell region and the terminal protection region, wherein before forming the gate structures, forming the insulated gate bipolar transistor includes: forming a ballast structure in the bulk layer in the transition region, and forming a protection structure in the bulk layer in the terminal protection region.
