Rigaku to Showcase X-Ray Metrology for Semiconductor Manufacturing at SEMICON West 2026 - EE Times Asia

Rigaku's SEMICON West 2026 appearance is not a product demo—it is a declaration that optical metrology has hit its physical ceiling below 2nm. With GAA and CFET architectures demanding 3D measurement through stacked layers, X-ray penetration shifts from optional to existential for yield. The chain reaction is structural. Upstream, it pulls demand for high-brightness microfocus X-ray sources and pixelated detectors. Downstream, it embeds directly into AI-driven process control loops at leading-edge fabs in Taiwan, China and South Korea. More critically, it carves a new measurement axis that erodes the two-decade optical metrology moat built by KLA and AMAT. On compliance: Japan's METI export controls create a paradox—Rigaku must navigate approval for advanced X-ray systems while its core tube and detector components remain single-sourced. Meanwhile, domestic Chinese players like Skyverse and Jingce are rapidly penetrating mature-node metrology, compressing Rigaku's window. Strategic response: AMAT, post-KLA integration, will almost certainly bundle X-ray capability into its metrology portfolio within 12 months. ASML, defending its EUV metrology franchise, will accelerate in-house R&D. Rigaku has roughly 18 months to own the "X-ray equals Rigaku" association before the field consolidates. The 12-to-24-month trajectory: X-ray metrology becomes a mandatory PDK specification. The long-tail effect—measurement data itself becomes a new asset class, feeding yield-prediction models and opening IP-licensing revenue for equipment vendors.
