In a method for producing a trench transistor, a substrate of a first conduction type is provided and a trench in the substrate and a gate dielectric in the trench are formed. A first conductive filling in the trench as a gate electrode on the gate dielectric and first source and drain regions are formed. An etched-back first conductive filling is produced by etching back the first conductive filling down to a depth below the first source and drain regions and second source and drain regions are formed. The second source and drain regions adjoin the first source and drain regions and extend to a depth at least as far as the etched-back first conductive filling. An insulation spacer above the etched-back first conductive filling is formed in the trench and a second conductive filling is provided in the trench as an upper part of the gate electrode.

A transistor is provided which advantageously utilizes a part of the area which, in conventional transistors, is provided for the isolation between the transistors. In this case, the channel width can be enlarged in a self-aligned manner without the risk of short circuits. The field-effect transistor according to the invention has the advantage that it is possible to ensure a significant increase in the effective channel width for the forward current ION compared with previously used, conventional transistor structures, without having to accept a reduction of the integration density that can be attained. Thus, by way of example, the forward current ION can be increased by up to 50%, without having to alter the arrangement of the active regions or of the trench isolation.
