Abstract
A semiconductor device is proposed. An example of the semiconductor device includes a semiconductor body having a first main surface. A trench structure extends into the semiconductor body from the first main surface. The trench structure includes a trench electrode structure and a trench dielectric structure. The trench dielectric structure includes a gate dielectric in an upper part of the trench dielectric structure and a gap in a lower part of the trench dielectric structure. The semiconductor device further includes a body region adjoining the gate dielectric at a sidewall of the trench structure in the upper part of the trench dielectric structure. The gate dielectric extends deeper into the semiconductor body along the sidewall than the body region.
