摘要： A semiconductor device includes a trench extending into a drift zone of a semiconductor body from a first surface. The semiconductor device further includes a gate electrode in the trench and a body region adjoining a sidewall of the trench. The semiconductor device further includes a dielectric structure in the trench. The dielectric structure includes a high-k dielectric in a lower part of the trench. The high-k dielectric includes a dielectric constant higher than that of SiO2. An extension of the high-k dielectric in a vertical direction perpendicular to the first surface is limited between a bottom side of the trench and a level where a bottom side of the body region adjoins the sidewall of the trench.

摘要： A semiconductor device includes a first trench and a second trench extending into a semiconductor body from a surface. A body region of a first conductivity type adjoins a first sidewall of the first trench and a first sidewall of the second trench, the body region including a channel portion adjoining to a source structure and being configured to be controlled in its conductivity by a gate structure. The channel portion is formed at the first sidewall of the second trench and is not formed at the first sidewall of the first trench. An electrically floating semiconductor zone of the first conductivity type adjoins the first trench and has a bottom side located deeper within the semiconductor body than the bottom side of the body region.
