Working with the Korea Advanced Institute of Science and Technology (KAIST), NASA is pioneering the development of tiny spacecraft, each made from a single silicon chip, that could slash interstellar exploration times.
Speaking at the IEEE International Electron Devices Meeting in San Francisco last December, NASA’s Dong-Il Moon detailed this new technology, which is aimed at ensuring such spacecraft survive the potentially powerful radiation they’ll encounter on their journey.

This study uses KAIST’s experimental “gate-all-around” nanowire transistor. These devices use nanoscale wires as the transistor channel instead of today’s fin-shaped channels. The gate-all-around device may not be well known today, but production is expected to rocket in the early 2020s. [See “ Transistors Could Stop Shrinking in 2021,” IEEE Spectrum, August 2016]. |
