## Onto Innovation Acquires 27% Stake in Japan's Rigaku, Targeting Next-Gen Chip X-Ray Metrology
In a strategic move to solidify its position in the semiconductor supply chain, U.S.-based Onto Innovation has acquired a significant 27% stake in Japan's Rigaku Corporation. This investment is a direct play to enhance capabilities in X-ray metrology, a critical technology for measuring and inspecting the increasingly complex structures of next-generation chips. The deal signals a targeted consolidation of expertise as the industry races to overcome the physical limits of semiconductor manufacturing.

The partnership directly links Onto Innovation's process control and metrology solutions with Rigaku's established strength in X-ray analysis equipment. The focus is on developing advanced metrology tools essential for high-volume manufacturing of leading-edge logic and memory chips, where nanometer-scale precision is non-negotiable. This collaboration is not a full acquisition but a strategic equity investment designed to accelerate joint technology development and secure a competitive edge in a high-stakes, capital-intensive market.

The move underscores the intense pressure and collaboration required across the global semiconductor equipment sector to enable future chip nodes. By aligning with Rigaku, Onto Innovation is not just buying a stake but is investing in a specialized technological pathway, potentially altering competitive dynamics in the metrology segment. It reflects a broader industry trend where forming deep, strategic partnerships is becoming as crucial as internal R&D to keep pace with the roadmap defined by chipmakers like TSMC, Intel, and Samsung.
