Rigaku Launches XTRAIA MF-3400 to Advance Precision Measurement for Next-Generation Semiconductor Manufacturing
Rigaku Corporation, a global leader in X-ray analytical technology and a key member of Rigaku Holdings Corporation (headquartered in Akishima, Tokyo; CEO: Jun Kawakami), has officially announced the launch of the XTRAIA MF-3400, a cutting-edge measurement instrument designed for use in semiconductor manufacturing. The device is engineered to precisely measure wafer thickness and material composition, supporting the increasingly complex requirements of next-generation semiconductor production. Through advanced measurement capabilities and improved throughput, the XTRAIA MF-3400 is positioned to substantially enhance manufacturing productivity for memory and AI-driven semiconductor devices.
As global demand for high-performance chips continues to accelerate—driven by expanding applications such as generative AI, large-scale data centers, and high-speed communication infrastructure—the semiconductor industry faces unprecedented pressure to deliver faster processing capability, higher density integration, and improved energy efficiency. Modern semiconductor structures now incorporate billions of microscopic transistors within a single chip, arranged in intricate three-dimensional designs. This rapid evolution requires extremely accurate measurement tools capable of handling ultra-fine film structures essential for mass production.
The launch of the XTRAIA MF-3400 addresses one of the industry’s most critical needs: stable and nondestructive measurement of advanced materials and thin-film layers with nanoscale precision. This innovation represents a major advancement for semiconductor manufacturers seeking to maintain high yields while introducing new materials and device architectures.
Responding to the Growing Demands of Advanced AI and Memory Technologies
The explosive growth in AI-driven applications has dramatically changed the types of semiconductors required for future digital infrastructure. For example, generative AI models process and store massive datasets, requiring memory chips that are not only larger in capacity but also significantly faster and more power-efficient. This shift is visible in markets like 3D NAND flash memory, DRAM, and logic semiconductor devices, where uniform film thickness, precise material layering, and consistent crystallinity directly impact overall performance and reliability.
As device structures become more three-dimensional, the challenge of maintaining uniformity across multilayer stacks increases substantially. Manufacturers must validate and control thin metal films measured in nanometers—thousands of times thinner than a human hair—without damaging the wafer or slowing down production. Traditional measurement solutions face limitations in speed, accuracy, and nondestructive evaluation capability.
Recognizing these industry challenges, Rigaku leveraged decades of expertise in X-ray science to design the XTRAIA MF-3400. The system introduces multiple advancements in speed, sensitivity, and automated analysis, enabling semiconductor manufacturers to achieve tighter control across high-volume production environments. Among its new capabilities is its ability to measure molybdenum, a material gaining attention for emerging memory applications and anticipated to play a significant role in next-generation designs.
Key Features and Technological Advantages of the XTRAIA MF-3400
The XTRAIA MF-3400 incorporates a collection of advanced measurement and analysis functions that significantly enhance capability over previous models. These features are engineered to support efficiency and accuracy at scale, helping manufacturers improve yield rates and accelerate time-to-market.
1. Dramatically Increased Measurement Throughput
The system delivers up to double the throughput of previous Rigaku devices. By increasing the X-ray dose and integrating a newly designed high-speed wafer transport system, the XTRAIA MF-3400 can process a much greater number of wafers per hour. This improvement directly reduces manufacturing time and increases productivity for high-volume semiconductor facilities.
2. Nondestructive Measurement with Sub-Nanometer Precision
With measurement capability on fields as small as 50 μm—narrower than the width of an individual human hair—the instrument achieves thickness measurement accuracy at the sub-nanometer level, finer than the thickness of a single atom. Such precision is essential for ensuring uniformity and insulation characteristics in advanced semiconductor structures.
3. Multiple X-Ray Analytical Functions on One Device
The system integrates three primary X-ray analytical techniques into a single platform:
- X-ray fluorescence (XRF) for composition analysis
- X-ray reflectance (XRR) for ultra-thin film thickness measurement
- X-ray diffraction (XRD) for evaluating crystalline structure
This multi-analysis capability allows a single device to perform a wide range of evaluation tasks that previously required multiple instruments. Additionally, users can automate processes by registering measurement conditions into recipe-based workflows tailored for objectives such as thickness determination, crystallinity, or structural analysis. This automation reduces operator workload and ensures consistent results across multiple production lines.
Industry Adoption and Future Market Prospects
The XTRAIA MF-3400 has already attracted early adoption from leading semiconductor manufacturers. KIOXIA Corporation and KIOXIA Iwate Corporation—key players in the global memory market—have decided to implement the system for mass-production of 3D NAND flash memory, a memory technology widely used in smartphones, computers, and data centers. With increasing demand for storage capacity and speed, 3D NAND continues to expand in importance across the semiconductor industry.
Looking beyond NAND flash, applications of the XTRAIA MF-3400 are expected to extend to:
- DRAM (volatile main-memory devices known for high-speed operation)
- Logic semiconductor devices (used for processing, control, and data handling)
As these segments head toward next-generation architectural transitions, measurement accuracy becomes critical for maintaining performance and production stability.
Rigaku anticipates strong commercial outcomes based on early market interest. When combined with sales of the device’s predecessor model, the company forecasts net sales of more than JPY 6 billion in FY2026. This projected growth reflects an expanding need for versatile and scalable instrumentation solutions capable of supporting modern semiconductor development.
Modular Design and Future Expansion
A key advantage of the XTRAIA MF-3400 is its flexible and customizable modular configuration, allowing manufacturers to build optimal measurement environments tailored to diverse production requirements. Through interchangeable units and application-specific options, semiconductor producers can scale functionality in alignment with product complexity or process changes.
This adaptability allows organizations to respond quickly to evolving technology trends—particularly important in an industry where process techniques, materials, and architecture are rapidly changing.
Leveraging this versatility, Rigaku plans to continue developing new applications for material and process evaluation. The company is targeting sustainable growth of 20% annually beginning in FY2027 for both the XTRAIA MF-3400 and its predecessor platform, demonstrating its long-term commitment to advancing semiconductor metrology and process control technologies.
