    摘要: A method of manufacturing a semiconductor device includes providing a semiconductor wafer and forming at least one first trench in the wafer having first and second sidewalls and a first orientation on the wafer. The first sidewall of the at least one first trench is implanted with a dopant of a first conductivity at a first implantation direction. The first sidewall of the at least one first trench is implanted with the dopant of the first conductivity at a second implantation direction. The second implantation direction is orthogonal to the first implantation direction. The first and second implantation directions are non-orthogonal to the first sidewall.

    摘要: A method of manufacturing a semiconductor wafer having at least one device trench extending to a first depth position includes providing a semiconductor substrate having first and second main surfaces and a semiconductor material layer having first and second main surfaces disposed on the first main surface of the semiconductor substrate and determining an etch ratio. The least one device trench and at least one monitor trench are simultaneously formed in the first main surface of the semiconductor material layer. The at least one monitor trench is monitored to detect when it extends to a second depth position. A ratio of the first depth position to the second depth position is generally equal to the etch ratio.
