    摘要: A method for fabricating a semiconductor device includes forming at least one body having two sidewalls by vertically etching a semiconductor substrate, forming a protective layer having open parts that expose portions of the both sidewalls of the body, forming a buffer layer that fills the open parts, and forming a buried bit line in the body by siliciding the buffer layer and a portion of the body between the buffer layer.
