Abstract:
1. A method of fabricating a data storage or semiconductor device or array of devices by processing a substrate having a plurality of aligned and substantially parallel features, the plurality of features having at least one common critical dimension, the method comprising: (a) supplying an energetic particle beam having a major dimension and a minor dimension that is smaller than the major dimension, the energetic particle beam having a substantially uniform flux distribution over at least a portion of the major dimension and divergence of the energetic particle beam defines the minor dimension; (b) indexing the substrate about an azimuthal axis by an angular increment which is an integer fraction of 360 degrees, to orient the at least one critical dimension of the plurality of features on the substrate with a first fixed angular orientation relative to the major dimension of the energetic particle beam; (c) translating the substrate relative to the energetic particle beam substantially perpendicular to the substantially parallel features; and (d) exposing the substrate to the energetic particle beam in a treatment zone during at least a portion of the translation.
