Pattern-multiplication via a multiple step ion beam etching process utilizing multiple etching steps. The ion beam is stationary, unidirectional or non-rotational in relation to the surface being etched during the etching steps, but sequential etching steps can utilize an opposite etching direction. Masking elements are used to create additional masking elements, resulting in decreased spacing between adjacent structures and increased structure density.
