  • From Lab to Fab: Rigaku Brings Process-Specific Metrology to SEMICON Taiwan 2025

    Comprehensive X-ray and optical solutions powering every stage of semiconductor manufacturing—from ingot to advanced packaging.

    Booth S7153 | TaiNEX Hall 1 & 2 | September 10–12, 2025

        By Jeanette Paz-Alegretti, Marketing Director, Semiconductor Metrology Division, Rigaku Corporation

    As devices become smaller, smarter, and more interconnected, the semiconductor industry faces growing complexity across materials, structures, and integration. From the front end of line through advanced packaging, manufacturing success depends on what happens below the surface, where hidden defects, stress, and impurities can compromise everything.

    At SEMICON Taiwan 2025, Rigaku Corporation is proud to make its first appearance, showcasing a comprehensive range of process-specific X-ray and optical metrology tools. These solutions span the entire semiconductor lifecycle, from crystal growth to final packaging, and empower engineers to see what others miss, optimize yield, and shorten development cycles.

    Crystal Growth and Ingot Orientation

    Metrology begins with the crystal. Rigaku’s FSAS II and FSAS III systems deliver high-throughput X-ray orientation analysis of silicon and compound semiconductor ingots. These tools verify alignment and crystal integrity before wafer slicing, critical for front-end quality.

    Crystal Growth and Wafer Inspection

    Post-slicing, Rigaku’s XRTmicron Lab and XRTmicron Near Fab platforms use advanced X-ray topography to detect dislocations, slip lines, and other structural defects in bare wafers up to 300 mm. These early-stage inspections help prevent defective substrates from entering the line.

    Wafer Preparation and Contamination Control

    Surface contamination is one of the most yield-critical issues in semiconductor fabrication. Rigaku’s TXRF 3760TXRF V310, and TXRF 310Fab systems perform ultra-trace elemental analysis using total reflection X-ray fluorescence (TXRF). These tools are optimized for cleanroom and inline fab environments, enabling contamination monitoring across wafer cleaning, transport, and process equipment.

    Photomask and Lithography

    As lithography advances to EUV and sub-10 nm nodes, precise inspection becomes increasingly essential. Rigaku offers XTRAIA XD-2000RXD-3000RCD-3010G, and CD-3200T platforms for multilayer mask inspection, CD metrology, strain mapping, and pattern fidelity verification, ensuring that both masks and patterned wafers meet design specifications.

    Etch Process Control

    Etched features must be clean, uniform, and reliable. The XTRAIA CD-3200T and XD Series provide high-resolution measurements of CDs, sidewall angles, and profile shapes. These insights support critical process tuning after deep etch steps, especially for high-aspect ratio features in 3D devices.

    Epitaxy and Thin Film Characterization

    Layer quality is fundamental to device performance. Rigaku’s XTRAIA MF-2000MF-3000WaferX 310, and XD Series offer advanced X-ray diffraction (XRD) and X-ray reflectometry (XRR) capabilities for monitoring epitaxial layers and thin films. These tools measure thickness, composition, stress, strain, and defect density with sub-nanometer precision.

    Labs and Fab Support

    Whether in a university lab or a pilot line, flexibility and accuracy are key. Rigaku’s SmartLab Series and XTRAIA TF-2000 offer versatile capabilities for crystal structure evaluation, material identification, and process development—bridging the gap between research and production.

    Advanced Packaging

    At the back end, interconnect integrity defines system performance. Rigaku’s ONYX 3000 and ONYX 3200 systems deliver precise measurements of bump height, under-bump metallization (UBM) thickness, and void detection. These tools support 2.5D and 3D packaging schemes, including chiplets, memory stacks, and hybrid bonding.
