Abstract
In a method of manufacturing a semiconductor device, a target layer to be patterned is formed over a substrate, a mask layer having an opening is formed over the target layer, the opening is enlarged in a first direction without enlarging the opening in a second direction crossing the first direction by a directional process, where the first and second directions are parallel to an upper surface of the substrate, and the target layer is patterned to form a hole corresponding to the opening.
