摘要:
A trench transistor structure having a field electrode arrangement formed in trenches is disclosed. In one embodiment, the field electrode arrangement is conductively connected to subvoltage taps of a voltage divider for the purpose of stabilizing the potentials on a longer time scale than dynamic charge reversal processes.
