    摘要: A method for fabricating a semiconductor device is provided, the method includes forming a plug conductive layer over an entire surface of a substrate, etching the plug conductive layer to form landing plugs, etching the substrate between the landing plugs to form a trench, forming a gate insulation layer over a surface of the trench and forming a buried gate partially filling the trench over the gate insulation layer.
