Abstract: PURPOSE: A method for manufacturing a pattern capable of preventing a misalignment is provided to improve planarity by entirely etching an oxide layer having high etching uniformity, and to prevent an inside of a contact from being contaminated by slurry or a polishing solvent without a chemical mechanical polishing method in a dual damascene process. CONSTITUTION: An oxide layer(22) is formed on a substrate having a lower interconnection. An etching mask for defining a contact hole(C) formation region is formed on the oxide layer. The oxide layer is selectively etched to form the first contact hole exposing the lower interconnection while a bowing part(B) is formed on a sidewall of the first contact hole separated from the lower interconnection by the length of a vertical interconnection. The etching mask is removed. The oxide layer is entirely etched to a central region of the bowing part. The second contact hole is formed to define a vertical interconnection region, in which the bowing part is located at the entrance of the second contact hole.
