Gigaphoton Launches Neon Recycling Technology for Advanced Semiconductor Lithography
Gigaphoton has introduced hTGM for ArF, an on-site gas recycling system designed to recycle neon used in ArF excimer lasers critical to advanced semiconductor manufacturing. The system achieves a 50% neon gas recycling rate and can reduce annual gas consumption by up to 470,000 liters while supporting up to five ArF laser units. The innovation addresses supply chain vulnerabilities caused by geopolitical risks affecting neon availability while helping semiconductor manufacturers maintain stable production operations.
Neon gas serves as a critical component in ArF excimer lasers, which are essential tools for manufacturing the most advanced semiconductor chips. Recent geopolitical tensions have created unpredictable supply disruptions, forcing chipmakers to seek alternative strategies for securing this rare resource. Gigaphoton's recycling system addresses this vulnerability by capturing and reprocessing spent neon directly within manufacturing facilities, rather than relying solely on external suppliers.
The hTGM for ArF system represents an extension of Gigaphoton's earlier work with similar recycling technology for KrF lasers. By designing the new system with compatible hardware components, the company aims to streamline manufacturing and deployment across multiple fab installations. The 50% recycling rate substantially reduces the volume of fresh neon required annually while allowing a single unit to serve multiple laser systems simultaneously.
This technology could help semiconductor manufacturers reduce their dependence on volatile international neon markets, potentially stabilizing production timelines and costs. Chipmakers may experience improved operational resilience during supply disruptions, which could indirectly benefit industries reliant on chip availability—from consumer electronics to automotive and data centers. The environmental impact may be positive through reduced resource consumption, though the broader geopolitical supply chain challenges would persist without complementary diversification efforts across the industry.
