A semiconductor device includes a semiconductor material, the
semiconductor material including a base region and a field stop zone
including a first side adjacent the base region and a second side
opposite the first side. The field stop zone includes a first dopant
implant and a second dopant implant. The first dopant implant has a first
dopant concentration maximum and the second dopant implant has a second
dopant concentration maximum with the first dopant concentration maximum
being less than the second dopant concentration maximum, and being
located closer to the second side than the second dopant concentration
maximum.
