| 摘要 |
Semiconductor device structures and related fabrication methods are provided. An exemplary semiconductor device structure includes a first vertical drift region of semiconductor material, a second vertical drift region of semiconductor material, and a buried lateral drift region of semiconductor material that abuts the vertical drift regions. In one or more embodiments, the vertical drift regions and buried lateral drift region have the same conductivity type, wherein a body region of the opposite conductivity type overlies the buried lateral drift region between the vertical drift regions. |
