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

Enhanced molecular patterning via microdisplacement printing
TL;DR: Here it is demonstrated the versatility of “microdisplacement printing,” a soft lithographic patterning technique that employs microcontact printing to replace pre-formed self-assembled monolayers (SAMs) selectively.

Composition for an Etching Mask Comprising a Silicon-Containing Material
TL;DR: In this article, a composition for a silicon-containing material used as an etch mask for underlying layers is presented, where the material can selectively etch the protrusions and the segments of the patterned imprinting layer in superimposition therewith, while minimizing the etching of the segments in superposition with the recessions.

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.
