HIGH-SPEED SELECTIVE JET ELECTRODEPOSITION OF GOLD AND COPPER

High Speed Selective Jet Electrodeposition (HSSJE) is a process by which metals may be electrodeposited in a spatially selective manner without the need for masking. This paper discusses the principles that underlie HSSJE and the factors that influence the rates of deposition, selectivity and deposit quality for both copper and gold. Also presented is an empirical model of how the hydrodynamic and electrochemical factors influence growth mechanisms and limit deposition rates. Potential applications of the process are also discussed.
