Tech Brief: Elements of Electroplating


Electroplating is a common manufacturing process that applies a thin layer of one metal onto another. The U.S. penny, for example, has been made of zinc with a thin, electroplated coating of copper since 1982. Jewelry and flatware are also frequently electroplated to improve visual appearance or provide wear and corrosion resistance. Today, electroplating is widely performed in the electronics ... » read more

How To Deal With Electromigration


The replacement of aluminum with copper interconnect wiring, first demonstrated by IBM in 1997, brought the integrated circuit industry substantial improvements in both resistance to electromigration and line conductivity. Copper is both a better and more stable conductor than aluminum. Difficult though the transition was, it helped extend device scaling for another eighteen years (and counting... » read more
