Key Takeaways
- • Indus Capital Partners Managing Partner Byron Gill told the Sohn Tokyo 2026 conference that a recently listed Japanese X-ray equipment maker in chip metrology is mispriced, valued by the market as a lab instrument business rather than a semiconductor production supplier.
- • Gill argues a new strategic shareholder could carry the company into high-volume chip production, with roughly 100% upside cited in the presentation.
- • Gill frames the thesis around the shift to 3D chip stacking, where optical inspection only reads the top layer and X-ray inspection, though precise, is slower and more expensive.
- • Gill identifies a hybrid of X-ray and optical metrology, enabled by machine learning and high-performance computing, as a potential breakthrough that combines precision with factory-line speed.
- • The pitch is presented by a hedge fund manager with a long Japan track record, including a current independent director seat at Fujitsu since June 2023.
Summary
Byron Gill, Managing Partner and Founder of Indus Capital Partners, presented an investment thesis at Sohn Tokyo 2026 arguing that a recently listed Japanese X-ray equipment maker is mispriced. According to Hedge Fund Alpha's coverage of the presentation, Gill contends the market still values the company as a lab instrument business, while a new strategic shareholder could move it into high-volume chip production, with roughly 100% upside cited.
Gill described semiconductor metrology as the diagnostic step between the hundreds of manufacturing stages required to produce an advanced chip, which can take several months. He noted that a defect discovered late can result in the loss of a chip worth $100,000. Optical inspection, which relies on light reflecting off a surface, sufficed when chips were flat and scaling followed Moore's law, because it is inexpensive, fast and well suited to in-line production.
The industry's shift to vertically stacked, three-dimensional chip architectures undermines that approach, according to Gill, because optical light reflects only from the top layer. Detecting defects deep within a 3D stack requires X-ray metrology, which can reach sub-nanometer precision but is slower and costlier. Gill argued that machine learning and high-performance computing make a hybrid of X-ray and optical inspection feasible, combining the precision of one with the throughput of the other. He called this "the holy grail of metrology right now."
Gill's background underpins the presentation. He was born in Japan, spent six years as a research analyst covering Japanese retail and consumer companies at SBC Warburg and Salomon Smith Barney, and ran Soros Fund Management's Tokyo office before founding Indus, where he manages the Indus Pacific Opportunities Fund. He has invested in Asian equities for more than 25 years and has served as an independent director of Fujitsu Ltd (TYO:6702) since June 2023.
