Abstract

This method involves the deposition of free metal atoms (4) from the apex (5) of a pointed tip (1) supported at a distance of 10 to 20 nm from a substrate (2). The atoms (4) are being field-desorbed under the influence of a strong electric field existing between the tip (1) and the substrate (2). With the tip (1) being moved across the substrate (2), a narrow trace (6) of metal atoms will be deposited on the substrate.
