Abstract:
An insulated gate bipolar transistor (IGBT) includes a substrate, including a device region and a collection region, arranged into a bilayer structure. The device region includes a plurality of control regions and a plurality of turn-off regions. The IGBT also includes a drift region formed in the control regions and the turn-off regions, and electrically connected to the collection region; a well region formed in the control regions and the turn-off regions, and in contact with the drift region; a plurality of first gate structures formed in the control regions, and in contact with the drift region and the well region; and a plurality of emission regions formed in the well region of the control regions, and on at least one side of each first gate structure. The emission regions are isolated from the drift region, and are electrically connected to the well region of the turn-off regions.

Claim (Index 18):
The method for fabricating the IGBT according to  claim 17 , further including:\n forming a gate electrode connection structure in the connection region to connect the plurality of first gate structures.
