A Touch Of Titanium Helps Chips Take Off

In their endless quest to boost computer-processing speeds, engineers may turn to a material now used to build advanced aircraft. Researchers at Georgia Institute of Technology have used titanium, a lightweight metal, to help speed up computer chips. A thin layer of titanium oxide acts as an adhesive between diverse materials in the chip. It allows engineers to replace the tiny aluminum wires inside the chips with wiring made of copper, gold, or silver. These metals, which don't bond to other electronic materials, are more conductive and let electrical signals travel faster.
