摘要： The disclosed technology relates to methods of patterning elongated structures. In one aspect, a method of forming pillars includes providing a substrate and providing a plurality of beads on a surface of the substrate. Regions of the surface without a directly overlying bead are exposed. The method additionally includes selectively etching the exposed regions of the substrate between the beads such that a plurality of pillars is formed under areas masked by the beads. Selectively etching completely removes at least some of the beads. The pillars that are not covered by beads are etched, thereby leaving some pillars taller than others, with the pillar height pending on the amount of time a pillar was left exposed to etchant by a removed bead.
