2.4.3 Atomic Force Microscope Lithography

Since the meniscus shape is driven by the shape of the needle tip, it can be concluded that the tip shape is the main factor which determines the oxide width dimensions []. Several ICM versus CM comparative studies have observed that ICM lithography enjoys a higher aspect ratio, allowing for the generation of smaller oxide widths, and produces higher oxidation rates [ 53 ], [ 55 ], [ 209 ].
