Power semiconductor devices having gate trenches with implanted sidewalls and related methods |
| abstract |
Semiconductor devices include a semiconductor layer structure having a wide band-gap semiconductor drift region having a first conductivity type. A gate trench is provided in an upper portion of the semiconductor layer structure, the gate trench having first and second opposed sidewalls that extend in a first direction in the upper portion of the semiconductor layer structure. These devices further include a deep shielding pattern having a second conductivity type that is opposite the first conductivity type in the semiconductor layer structure underneath a bottom surface of the gate trench, and a deep shielding connection pattern that has the second conductivity type in the first sidewall of the gate trench. The devices include a semiconductor channel region that has the first conductivity type in the second sidewall of the gate trench. |
