Abstract
The application relates to a semiconductor die including a device in an active area of the die. The device includes a field electrode region formed in a field electrode trench extending vertically into a semiconductor body. The field electrode region includes a first and a second field electrode stacked vertically above each other in the field electrode trench. An edge termination structure laterally between the active area and a lateral edge region of the die includes a first and a second shield electrode arranged laterally consecutive between the active area and the lateral edge region to stepwise decrease an electrical potential between the edge region and the active area.
