Tokyo University spin‑off Gaianixx is accelerating capacity expansion to capture rising AI-driven demand for chip materials. CEO Kento Nakao said the company will enlarge its Yamanashi technical centre southwest of Tokyo, which currently processes about 15,000 8‑inch wafers a year. Nakao said the firm’s most advanced project could enter trial production by year‑end, and that one Japanese customer and one overseas customer have committed to use Gaianixx materials to develop devices. The expansion comes as chipmakers increasingly seek performance gains from advanced materials amid slowing transistor‑scaling improvements.
