    Overview: Silicon Photonics Wafer-Level Test Solutions for AI and CPO Applications

    Driven by the escalating bandwidth demands of AI servers and modern data centers, the transition toward optical interconnects and Co-Packaged Optics (CPO) has become an industry imperative. However, with the increasing complexity of heterogeneous integration, accurately screening for Known Good Die (KGD) prior to advanced packaging is now a critical prerequisite for effective yield management and mitigating subsequent packaging losses. 

    Enlitech’s NightJar™ Silicon Photonics Wafer-Level Test Solution is engineered to overcome the bottlenecks of PIC defect feature detection, anomaly coordinate localization via Hyperspectral Inspection Technology, and testing throughput in SiPh high-volume manufacturing. The system supports comprehensive O-to-O (Optical-to-Optical) evaluations and integrates seamlessly with customers’ existing automated probers, facilitating a highly efficient automated test flow from the R&D lab to the production floor.

    Comprehensive On-Wafer Test Coverage from WAT, CP to FT

    NightJar™ is a highly versatile test platform capable of upgrading existing electrical probe stations into systems with advanced optical testing capabilities, supporting the full lifecycle testing requirements of silicon photonics chips:

    • WAT (Wafer Acceptance Test): Performs optical and electrical parameter acceptance testing on PCM structures before wafer shipment.
    • CP (Chip Probing): Executes wafer-level functional testing to perform KGD screening, reducing scrap costs in backend advanced packaging (e.g., CoWoS, CPO).
    • FT (Final Test): Verifies the final optical performance of diced or packaged SiPh modules.

    Supported Wafer Sizes and Test Phases

    Test phases: WAT wafer acceptance, CP probing, FT final test

    The system supports the integration and upgrade of various mainstream probers and ATEs (Automated Test Equipment) for silicon photonic chips. It has extensive multi-brand integration and upgrade capabilities, supporting brands like TEL, Accretech, Formfactor, Advantest, and MPI. 

    4–12 inch silicon photonics wafer test support

     Compatible with various wafer sizes ranging from 4 to 12 inches.

    System design

    Reference Cells

    Enlitech provides the world’s most comprehensive selection of reference cells, compliant with WPVS types and IEC 60904 standards. The purpose of reference cells is to assist in accurate solar cell characterization, keeping pace with the rapid development of various emerging solar cell technologies. Unique optical filter embedding technology helps establish different spectral wavelength response ranges for reference cells, which can reduce spectral mismatch between solar simulators and emerging solar cells. Calibrated reference cells are an indispensable part of solar simulator calibration and accurate solar cell characterization. Enlitech’s calibration laboratory is certified to ISO/IEC 17025 standards. All SRC-2020 series reference cells are calibrated with traceability to NIST. Enlitech also provides reference cell recalibration services. 09_SRC-2020_標準電池 Enlitech provides various solar reference cells for calibrating the irradiance intensity of solar simulators or daylight simulators. Spectral response curves are shown below. Each reference cell kit includes a WPVS-packaged silicon reference cell with optical window, two Lemo connector cables, and a certified daylight intensity calibration report.

    IVS-KA6000: The Most Powerful Current-Voltage Measurement Software

    2024Enlitech-Reference-Cell-Spectral-Chart-1
    2024Enlitech-Reference-Cell-Spectral-Chart2

    All SS-X series solar simulators can be controlled by IVS-KA6000, the most powerful current-voltage (IV) measurement software for precise photovoltaic characterization analysis. Not only optical shutters, but output irradiance can also be controlled by IVS-KA6000 software. This enables users to easily complete complex IV testing under different irradiance levels or solar cell open-circuit voltage (Sun-Voc) testing. All data from IVS-KA6000 can be read and analyzed through IVS-KA-Viewer, another versatile analysis software.

    Previously, measuring and fitting the ideality factor n of solar cells was not easy and time-consuming. For example, it typically required one hour to obtain 10 IV curves under 10 different irradiance levels, followed by approximately another hour to organize the data. However, with our testing solution combining SS-X Solar Simulators, IVS-KA6000, and IVS-KA-Viewer, ideality factor N can be measured and fitted within minutes.
