    摘要: A method for fabricating gate electrodes (7) in a field plate trench transistor (1) having a cell array with a plurality of trenches (3) and a plurality of mesa regions (8) arranged between the trenches comprises the following steps: application of a gate electrode layer (7) to the cell array in such a way that the gate electrode layer (7) has depressions within or above the trenches (3), application of a mask layer (10) to the cell array, etching-back of the mask layer (10) in such a way that mask layer residues (10) remain only within the depressions of the gate electrode layer (7), and etching-back of the gate electrode layer (7) using the mask layer residues (10) as an etching mask in such a way that gate electrode layer residues (7) remain only within/above the trenches (3).
