Fully ultrahigh-vacuum-compatible fabrication of submicrometer-spaced electrical contacts

Gärtner, C.; Hoffman, R.; Pérez-Willard, F.; Sauter, M.; Sürgers, Christoph; Löhneysen, Hilbert von

We present an approach by which submicrometer-spaced electrical contacts can be fabricated on virtually any surface under ultrahigh-vacuum conditions. The metallic contacts are formed by subsequent deposition through a macroscopic mask and a nanostructured stencil mask. The stencil mask with a high aspect ratio was obtained by nanopatterning of suspended low-stress Si3+xN4−x membranes with a focused ion-beam system. The fabricated contacts can be electrically connected in situ by simply exchanging the mask carrier by a second, spring-loaded, carrier.
