Method for fabricating a trench MOS power transistor |
摘要 |
A method for fabricating a trench MOS transistor includes the step of at least partly filling the trench with a conductive material which is isolated from the inner surface of the trench by an insulating layer. The insulating layer has a layer thickness that is larger in the region of the lower end of the trench than at the upper end of the trench.
