Samenvatting
Electroplating of gold is often used in optoelectronic and microelectronic devices
for air-bridges, heat-sinks or gold-bumps for flip-chip techniques. The gold-cyanide
electrolytes, which are commonly used in gold-electroplating, are toxic and attack resist
patterns causing cracks during the plating process. In this paper we report our experimental
results of gold-electroplating using a sulfite-based electrolyte (NH4)3{Au(SO3)2}. This
product is environment- and userfriendly and moreover the electroplating rate is good (10-50
µm/hour). Results varying current density and stirring rate will be reported.
