Signing ceremony with imec held on April 9

As part of this initiative, Rigaku is working with imec, a world-leading semiconductor research and innovation hub headquartered in Belgium, under a three-year development program. Through this effort, Rigaku will advance its core X-ray technologies, including 3D device metrology, high-sensitivity detection of ultrathin films and trace elements, and non-destructive inspection of microscopic defects.

As semiconductor devices evolve toward advanced architectures such as Gate-All-Around (GAA) and Complementary FET (CFET)¹, along with increasing memory density, manufacturing processes are becoming more complex. These drives growing demand for highly accurate, non-destructive measurement and inspection technologies to support stable mass production. Rigaku addresses these needs by delivering high-value, differentiated metrology and inspection solutions.

Key focus areas

• Advanced logic: Metrology and inspection technologies for CFET devices
• Reticle metrology: Evaluation of photomask degradation used in EUV² lithography
• Advanced wiring and packaging³: Non-destructive inspection technologies
• Advanced memory: Evaluation of nanostructures in 3D DRAM (a next generation memory device)

Markus Kuhn, Executive Officer and General Manager of Semiconductor Metrology Division of Rigaku, commented, “The serviceable available market (SAM) for Rigaku’s metrology and inspection products in the advanced AI semiconductors is expected to reach approximately US$1 billion by 2030. To address this market growth, Rigaku will continue introducing high‑value, differentiated products, with the goal of achieving a 50% share of this SAM. Strengthening our collaboration with imec will further enhance our competitiveness in high value-added measurement and inspection, supporting medium- to long-term growth.”

1 GAA/CFET: Gate-All-Around / Complementary Field-Effect Transistors. A next-generation device architecture in which n-type and p-type transistors are vertically stacked to increase device density beyond nanosheet (GAA) technology.
2 EUV exposure: A core technology for advanced semiconductor manufacturing that enables the formation of ultrafine circuit patterns.
3 Advanced packaging: Packaging technologies that integrate multiple semiconductor chips to enhance performance and reduce power consumption
