Abstract:
A method of forming a pattern includes forming a lower layer on a substrate, forming a mask pattern on the lower layer, the mask pattern extending in a first direction parallel to a top surface of the substrate, and performing an etching process using an ion beam on the substrate, such that the ion beam is irradiated in parallel to a plane defined by the first direction and a direction perpendicular to the top surface of the substrate, and is irradiated at a tilt angle with respect to the top surface of the substrate, wherein performing the etching process includes adjusting the tilt angle of the ion beam to selectively etch the lower layer or the mask pattern.

Claim (Index 5):
The method as claimed in  claim 1 , wherein forming the mask pattern includes forming a plurality of mask patterns extending in the first direction and spaced apart from each other in a second direction intersecting the first direction,\n wherein the second direction is parallel to the top surface of the substrate, and the direction perpendicular to the top surface of the substrate is a third direction, and wherein performing the etching process further includes adjusting a rotation angle of the ion beam in such a way that the ion beam is irradiated in parallel to the plane defined by the first direction and the third direction.
