Abstract:
1. A method comprising: forming a nanodot material on a substrate; forming an oxide block on the nanodot material; forming a nitride film on the substrate; patterning the nitride film to form a nitride spacer; removing the oxide block to form a free standing nitride spacer removing exposed portions of the nanodot material and then the free standing nitride spacer to form nanowires; forming an orthogonal oxide block at a substantially orthogonal angle to a length of the nanowires; forming an orthogonal nitride spacer on the orthogonal oxide block; removing the orthogonal oxide block to form an orthogonal free standing nitride spacer; and removing an exposed portion of the nanowires and then the orthogonal free standing nitride spacer to form an ordered array of nanodots on the substrate.
