摘要： According to a disclosed semiconductor device fabrication method according to one embodiment of the present invention, a layer having a line-and-space pattern extending in one direction is etched using another layer having a line-and-space pattern extending in another direction intersecting the one direction, thereby obtaining a mask having two-dimensionally arranged dots. An underlying layer is etched using the mask, thereby providing two-dimensionally arranged pillars.
