Chips make them rich
even for the most rich and famous, every penny counts. So is the case with the Silicon Valley that is troubled by the rising cost of making silicon chips. The soaring costs are due to a complicated process known as photolithography which is used for fixing transistors and wires on silicon. Recently a group of electrical engineers have come up with a technique that could be the answer to the valley's woes.
Stephen Chou, Chris Keimel and Jian Gu of the us-based Princeton University claim that it is possible to stamp minute features on to melted silicon, just as a seal is stamped on to softened wax. To perform their trick, which they have dubbed
