    摘要: A semiconductor power device having shielded gate structure integrated with a trenched clamp diode formed in a semiconductor silicon layer, wherein the shielded gate structure comprises a shielded electrode formed by a first poly-silicon layer and a gate electrode formed by a second poly-silicon layer. The trenched clamp diode is formed by the first poly-silicon layer. A shielded gate mask used to define the shielded gate is also used to define the trenched clamp diode. Therefore, one poly-silicon layer and a mask for the trenched clamp diode are saved.
