Silicon carbide device with trench gate structure and method of manufacturing
A silicon carbide device includes a silicon carbide body having a hexagonal crystal lattice with a c-plane and with further main planes. The further main planes include a-planes and m-planes. A mean surface plane of the silicon carbide body is tilted to the c-plane by an off-axis angle. The silicon...

| Zusammenfassung: | A silicon carbide device includes a silicon carbide body having a hexagonal crystal lattice with a c-plane and with further main planes. The further main planes include a-planes and m-planes. A mean surface plane of the silicon carbide body is tilted to the c-plane by an off-axis angle. The silicon carbide body includes a columnar portion with column sidewalls. At least three of the column sidewalls are oriented along a respective one of the further main planes. A trench gate structure is in contact with the at least three of the column sidewalls. |
