UK company shoots a 1000-degree furnace into space to study off-world chip manufacturing — semiconductors made in space could be 'up to 4,000 times purer' than Earthly equivalents

A team from Cardiff, Wales, is experimenting with the feasibility of building semiconductors in space, and its most recent success is another step forward towards its goal. According to the BBC, Space Forge’s microwave-sized furnace has been switched on in space and has reached 1,000°C (1,832°F) — one of the most important parts of the manufacturing process that the company needs to validate in space.

“This is so important because it’s one of the core ingredients that we need for our in-space manufacturing process,” Payload Operations Lead Veronica Vera told the BBC. “So being able to demonstrate this is amazing.” Semiconductor manufacturing is a costly and labor-intensive endeavor on Earth, and while putting it in orbit might seem far more complicated, making chips in space offers some theoretical advantages. For example, microgravity conditions would help the atoms in semiconductors line up perfectly, while the lack of an atmosphere would also reduce the chance of contaminants affecting the wafer.
