AwesomeRay commercializes carbon nanotubes for semiconductors and defense in South Korea

South Korean startup AwesomeRay is turning carbon nanotubes (CNT) from a lab material into real products for semiconductors, defense, and mobility. The company produces CNT in fiber and membrane form, not powder, which has been the main barrier to industrial use. Its first target is EUV protective films for advanced chipmaking, a market that could grow as high performance semiconductor production ramps up. AwesomeRay has raised about 27 billion won to date and expects full scale revenue in the second half of 2026, aiming for 10 billion won in annual sales by 2028. The company was founded in 2018 by researchers from Seoul National University and has filed 113 IP applications. It recently won an innovation award at Techtextil Frankfurt for its CNT membrane technology. After pivoting from X-ray and air purification businesses, AwesomeRay now focuses on CNT fibers and membranes for semiconductors, defense, aerospace, and mobility. The article does not specify the carbon footprint or lifecycle impact of CNT production, which would be relevant for assessing its environmental benefit.

Interesting to see CNT finally moving past the lab stage. The EUV pellicle application is a real market need. But I wonder what the energy cost of producing these fibers is compared to the alternatives.

Good point. The article says they raised 27 billion won and aim for 10 billion won sales by 2028. That is a long runway. Would be useful to know the carbon footprint per kg of CNT fiber versus traditional materials.

CNT membranes for EUV pellicles is a niche but high value application. The real question is whether they can scale production without massive energy input. The article does not mention energy use or yield rates.

They claim to be the only company producing both CNT fibers and membranes. That is a strong moat if true. But the article is light on technical details about the synthesis process and its energy intensity.

The pivot from X-ray and air purification to semiconductors and defense makes sense given market timing. But I would like to see how South Korean industrial policy or subsidies support this kind of advanced materials startup. The article does not mention any government backing.

Agreed. Without policy support, scaling CNT production for defense and aerospace will be capital intensive. The 7-9 billion won bridge round is modest for industrial scale up. Curious about their production cost per square meter of membrane.
