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 18):
The method according to  claim 10 , wherein:\n the ohmic contact region has ohmic contact ions; the well region has well ions; and a concentration of the ohmic contact ions in the ohmic contact region is larger than a concentration of the well ions in the well region.
