“…[21][22][23][24] In the present study an Au-NP film pattern on Si substrate was immersed in a Cu electroless deposition liquid. After electroless deposition for 3 min at 25 8C, a Cu film pattern was obtained, as shown in Figure 4.…”
Summary: In this report an ultrathin Au nanoparticle (AuNP) film composed of photosensitive diazoresin (DR) and mercaptophenol (MP) capped AuNPs (MP‐AuNPs) was fabricated by self‐assembly (SA). The DR/MP‐AuNP film was then patterned through a photomask by selective exposure to UV light and instantly developed in sodium dodecyl sulfate (SDS) aqueous solution. After sintering at 550 °C to remove the organic components, the DR/MP‐AuNPs formed AuNPs. Taking advantage of the catalytic susceptibility of AuNPs toward electroless deposition of Cu, a Cu film micropattern with fine resolution (ca. 2–3 μm) and considerable thickness (ca. 130 nm) was prepared.SEM image of the micropatterned Cu film on a silicon substrate; scale bar: 10 μm.magnified imageSEM image of the micropatterned Cu film on a silicon substrate; scale bar: 10 μm.
“…In the SEM microphotographs, shown in Figs. 9-12, the exposed T4 emulsion has been fixed after removing the gelatin and subsequently treated with the physical developer FC 3 -a so-called surfactant stabilized developer -according to Jonker et al (1971). Figs.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
