Abstract
A method for fabricating a semiconductor device includes forming electrode patterns over a substrate, wherein the electrode patterns include a hard mask, forming a passivation layer on the electrode patterns, forming an insulation layer on the passivation layer, filling a space between the electrode patterns, planarizing the insulation layer until shoulder portions of the hard mask are planarized, forming a mask pattern on a resultant structure, and etching a portion of the insulation layer to form a contact hole.
