Abstract:
A method of manufacturing a power semiconductor device includes: creating a doped contact region on top of a surface of a carrier; creating, on top of the contact region, a doped transition region having a maximum dopant concentration of at least 0.5*10 15  cm −3  for at least 70% of a total extension of the doped transition region in an extension direction and a maximal dopant concentration gradient of at most 3*10 22  cm −4 , wherein a lower subregion of the doped transition region is in contact with the contact region and has a maximum dopant concentration at least 100 times higher than a maximum dopant concentration of an upper subregion of the doped transition region; and creating a doped drift region on top of the upper subregion of the doped transition region, the doped drift region having a lower dopant concentration than the upper subregion of the doped transition region.

Claim (Index 5):
The method of  claim 1 , further comprising introducing dopants of the doped contact region during the at least one epitaxy processing step.
