The silicon oxide layer applied using inert barrier technology is around 500 times thinner than a human hair.
Therefore, instead of soft silicon hydroxide, a silicon oxide layer is speculated to form on processed protuberance and groove surfaces.
A voltage run across a thin sheet of silicon oxide strips oxygen atoms away from a channel 5 nanometers (billionths of a meter) wide, turning it into conductive metallic silicon.
Unlike other silicon oxide chips currently in development, the UCL chip does not require a vacuum to work, and is therefore potentially cheaper and more durable.
recently announced they have co-launched a working chip built on a new, 65-nanometer silicon oxide nitride oxide silicon (SONOS) technology for embedded Flash memory.
"I was disappointed why I could see a clear picture, and I was confused why other people didn't see it." Thus did Jun Yao of Rice University describe his path toward elucidating the conducting and memory properties of silicon oxide (Si[O.sub.x]) as a graduate student studying carbon memory devices.
