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 17):
The method as claimed in  claim 12 , wherein performing the etching process further includes pre-treating the mask patterns to remove at least a portion of the mask patterns before etching the lower layer,\n wherein the mask patterns include at least one of a silicon oxide, a silicon nitride, or a metal nitride, and the lower layer includes a metal, and wherein the tilt angle of the ion beam is adjusted to an angle greater than 0 degree and equal to or less than 60 degrees.
