TLDR
In this paper, a technique for patterning a self-assembled monolayer (SAM) on a gold substrate using an elastomer stamp was described, followed by selective etching in an aqueous, basic solution of cyanide ion and dissolved dioxygen (1M KOH, 0.1 M KCN).Abstract:
This letter describes a technique that can be used to produce well‐defined features of gold. The technique involves patterning of a self‐assembled monolayer (SAM) on a gold substrate using an elastomer stamp (fabricated either from a phenol‐formaldehyde polymer or polydimethylsiloxane), followed by selective etching in an aqueous, basic solution of cyanide ion and dissolved dioxygen (1M KOH, 0.1 M KCN). Electrically conductive structures of gold with dimensions as small as 1 μm have been produced using this procedure. Once a rubber stamp is fabricated, patterning and etching of gold substrates is straightforward. This method is convenient, does not require routine access to clean rooms and photolithographic equipment, and can be used to produce multiple copies of a pattern.read more

Fabrication of large-area stamps, moulds, and conformable photomasks for soft lithography
TL;DR: In this article, it was proposed that extending flexography into the micrometre-size resolution regime may provide an economical commercialization path for plastic devices, and the use of these plates for three representative soft lithographic processes: microcontact printing, replica molding, and phase shift lithography.

The use of self-assembled monolayers and a selective etch to generate patterned gold features
TL;DR: Using a number of techniques, such as micromachining, microwriting, electron-beam lithography, ion-beam, and ion beam, it is possible to form patterns of SAMs on the Au surface.
