Scientists at Rice University have developed a new silicon oxide chip manufacturing technology that involves filaments as thin as five nanometers. The inventors claim that within five years, the research may lead to tiny chips that store as much as today's highest capacity HDDs:
More important, the advance is based on silicon oxide, one of the basic building blocks of today’s chip industry, thus easing a move toward commercialization. The scientists said that PrivaTran, a Texas startup company, has made experimental chips using the technique that can store and retrieve information.
These chips store only 1,000 bits of data, but if the new technology fulfills the promise its inventors see, single chips that store as much as today’s highest capacity disk drives could be possible in five years. The new method involves filaments as thin as five nanometers in width — thinner than what the industry hopes to achieve by the end of the decade using standard techniques. The initial discovery was made by Jun Yao, a graduate researcher at Rice. Mr. Yao said he stumbled on the switch by accident.
