Abstract

A method for forming an array of nanostructures is presented. The method comprising: providing a layer structure including an array of first sacrificial nanostructures arranged on a supporting layer structure comprising at least a first material layer and a substrate; selectively applying spacer structures on sidewalls of the array of first sacrificial nanostructures; selectively etching away the array of first sacrificial nanostructures such that the spacer structures form an array of second sacrificial nanostructures; etching the first material layer using the array of second sacrificial nanostructures as an etching mask; and removing the array of second sacrificial nanostructures thereby exposing an array of nanostructures formed from the first material layer
