Zusammenfassung: | A method and an apparatus of patterning a substrate are provided. The method may include providing a cavity in a layer, disposed on the substrate, the cavity having a first length along a first direction and a first width along a second direction, perpendicular to the first direction, and wherein the layer has a first height along a third direction, perpendicular to the first direction and the second direction. The method may include depositing a sacrificial layer over the cavity in a first deposition procedure; and directing angled ions to the cavity in a first exposure, wherein the cavity is etched, and wherein after the first exposure, the cavity has a second length along the first direction, greater than the first length, and wherein the cavity has a second width along the second direction, no greater than the first width. |
