    摘要: The invention provides a trench gate type transistor in which the gate leakage current is prevented and the gate capacitance is reduced. A trench is formed in an N− type semiconductor layer. A thin silicon oxide film is formed on a region of the N− type semiconductor layer for the active region of the transistor in the trench. On the other hand, a silicon oxide film which is thicker than the silicon oxide film is formed on a region not for the active region. Furthermore, a leading portion extending from inside the trench onto the outside thereof forms a gate electrode contacting the silicon oxide film. This provides a long distance between the gate electrode at the leading portion and the corner portion of the N− type semiconductor layer, thereby preventing the gate leakage current and reducing the gate capacitance.
