Abstract
In the case of the cost-effective method according to the invention for fabricating a power transistor arrangement, a trench power transistor arrangement () is fabricated with four patterning planes each containing a lithography step. The power transistor arrangement according to the invention has a cell array () with cell array trenches () each containing a field electrode structure () and a gate electrode structure (). The field electrode structure () is electrically conductively connected to the source metallization () by a connection trench () in the cell array ().
