Image: Intel Wired Up: This Intel transistor, seen in cross section, uses cobalt for lower-resistance wiring. Today’s computer chips contain tens of kilometers of copper wiring, built up in 15 or so layers. As the semiconductor industry has shrunk the size of transistors, it has also had to make these interconnects thinner. Today, some wiring layers are so fine that electrical current can actually damage them. And chipmakers are running out of new ways to deal with this problem. Companies are now eyeing other materials, such as cobalt, ruthenium, even graphene, to replace copper for on-chip wiring. In December at the IEEE International Electron Devices Meeting (IEDM), in San Francisco, some seemed ready to anoint cobalt as the chosen metal. Intel described adopting the metal in its ­10-nanometer chips’ finest interconnects; Intel and ­GlobalFoundries both presented details...
