"NANOTECH: Deposition technique spins metal salt into pure gold"
Researchers at Purdue University have tapped an inexpensive wet-chemistry method to deposit nanoscale patterns of gold, platinum or palladium directly on top of semiconductor chips. While limited at present to gallium arsenide and germanium substrates, the work could enable a low-cost alternative to current metal deposition methods in chip manufacturing. It may also hold promise for the development of single-chip biohazard sensors to combat terrorism.
