Abstract:
A bipolar semiconductor device with a hole current redistributing structure and an n-channel IGBT are provided. The n-channel IGBT has a p-doped body region with a first hole mobility and a sub region which is completely embedded within the body region and has a second hole mobility which is lower than the first hole mobility. Further, a method for forming a bipolar semiconductor device is provided.
