Dimethylamine Borane as the Reducing Agent in Electroless Plating Systems

Abstract

composition of such a complex cannot be deduced from our results. We only know that the Sn: Pd ratio is about 2:1 and that an excess of C1 is present before heating in water. Whether the Pd occurs in a univalent or a bivalent state is not known.No suggestion can be made about the mechanism of initiation of the nickel deposition of the nucleated glass surface. We could not detect a metallic film after a treatment with a hypophosphite solution. Possibly the Sn-Pd complex reduces the nickel-ions. Further study is necessary to solve this problem. AcknowledgmentThe authors wish to thank J. R. ABSTRACTA chemical plating technique has been devised for the preparation of semitransparent photomasks. The deposited thin film meets the optical requirement of being opaque in the ultraviolet range and transparent enough in the visible range for see-through applications. Suitable etchants are available to provide good edge definition of photolithographically delineated semitransparent films without deteriorating common resist compositions. Analytical characterization of the deposited films revealed that they are primarily composed of cuprous oxide. The major advantage of the present approach is the low cost. Masks made by the present system are more durable (harder) than emulsiontype masks, but less durable than iron oxide semitransparent masks.In the manufacturing of electronic parts, photomasks are widely used in defining images on photosensitive * Electrochemical Society Active Member.

Recent advances in electroless nickel‑boron coatings

“…In the case of EN-B reduced by dimethylamine borane, this issue is less significant as the bath works in acid media, and most parts of the baths are stabilized by organic acids such as boric acid [140], sodium citrate [141], sodium lauryl sulfate [10] and gluconic acid [142].…”

Efficient surface modification of carbon nanotubes for fabricating high performance CNT based hybrid nanostructures

“…Such non-uniform silver growth is likely a result of the fast reaction between the silver cations and glucose. Besides using conventional glucose for reduction, previously reported silver growth methods employing, for example, sodium borohydride or dimethylamine borane species as reducing agents unavoidably lead to the generation of hydrogen gas during the reactions [32,33]. Hydrogen bubbles can take over the nucleation sites on the surface of the CNTs and interfere in the morphology and coverage ratio of silver nanoparticles.…”

Kinetic studies of gold(III) chloride complex reduction and solid phase precipitation in acidic aqueous system using dimethylamine borane as reducing agent

“…It shows good reactivity towards noble metals at ambient temperature. This reductant has been widely used in electroless deposition of gold (Sadik et al, 2005; or palladium (Lelental, 1973), although application for synthesis of platinum or gold nanoparticles was also reported (Hüttl et al, 2009;.…”
