Semiconductors made in space may be better than those made on Earth. A U.K. based start-up is preparing to send a satellite to space that will manufacture new semiconductor materials that could be used in electronic devices on Earth. The company, Space Forge, lost their first experimental satellite in the failed launch of Virgin Orbit's LauncherOne rocket from Cornwall, the U.K., in January. Their new satellite, called ForgeStar-1, is about to ship to the U.S. for a launch at the end of this year or in early 2024.
Semiconducting materials are essential for all sorts of electronic technologies, but their manufacturing on Earth is costly and energy intensive. The vacuum and microgravity conditions of space, however, could allow completely new semiconductor materials to be developed much more efficiently. Space Forge has recently signed a collaboration agreement with American aerospace giant Northrop Grumman to provide space-made semiconductor substrates that Northrop can then further develop in their foundries.
Producing compound semiconductors is a very intense and very slow process, they are literally grown by atoms. And so, gravity has a profound effect, basically shifting the bonds between those atoms. In space you're able to overcome that barrier, because there's an absence of gravity. Space also provides a perfect vacuum, which is necessary to protect the sensitive material from contamination. The combination of the microgravity and vacuum of space can enable researchers to create semiconductors that are 10 to 100 times more efficient semiconductors than you have on Earth.
The microwave-sized ForgeStar-1 satellite contains a miniature, automated chemistry lab that will allow the team to remotely mix various chemical compounds and develop new semiconducting alloys once the satellite is in orbit. But rather than sending the materials back to the planet, ForgeStar-1 will beam the results of these experiments to scientists digitally as this satellite is not designed to return to Earth. But the company's subsequent mission will be built to survive the fiery return through the atmosphere and bring its products back to Earth.
