发明名称 Method for fabricating semiconductor device with vertical channel
摘要 A method for fabricating a semiconductor device with a vertical channel includes providing a substrate over which a hard mask pattern is formed, forming pillars over the substrate using the hard mask pattern thereby forming a resultant structure, forming an insulation layer over the resultant structure, planarizing the hard mask pattern and the insulation layer until the pillars are exposed, and forming a storage electrode over the exposed pillars.
