发明名称 Method for fabricating semiconductor device including recess gate
摘要 A method for fabricating a semiconductor device includes forming a hard mask pattern over a substrate having a field oxide layer, etching the substrate to form a recess by using the hard mask pattern, forming a first conductive layer over the recess and the hard mask pattern, planarizing the first conductive layer, and forming a second conductive layer over the planarized first conductive layer.
