[Industry News] Bridging the Gap to Mass Production: Enlitech Partners with iST to Build Advanced CPO Optoelectronic Verification Platform

With the explosive growth in demand for Artificial Intelligence (AI) and High-Performance Computing (HPC), “Silicon Photonics (SiPh)” and “Co-Packaged Optics (CPO)” technologies—designed to breakthrough the physical limits of electronic transmission—have become the focal point of the global semiconductor industry. However, as signal transmission transitions from “electrical” to “optical,” verification complexity multiplies, creating a significant threshold that must be crossed before mass production.

To assist the industry in overcoming this critical bottleneck, Enlitech announced a deep technical collaboration with iST (Integrated Service Technology), a leading electronic verification and analysis laboratory. iST has adopted Enlitech’s Night Jar™ Silicon Photonics Testing Solution. By integrating Enlitech’s expertise in optics with iST’s strength in electronics, the partnership aims to build a comprehensive, one-stop high-end optoelectronic verification platform for the semiconductor supply chain, accelerating the transition of Silicon Photonics from the lab to high-volume manufacturing (HVM).

Industry Pain Points: Undetectable Optical Loss and Hidden Hotspots

Current CPO R&D and mass production introduction processes face immense challenges in the heterogeneous integration of Photonic Integrated Circuits (PIC) and Electrical Integrated Circuits (EIC). Traditional Optical Wafer Acceptance Tests (OWAT) often rely on total value measurements, which typically only indicate that “optical signal loss exists” without precisely pinpointing “where the leakage is” or “the exact location of the loss.”

This “speculative” testing blind spot prevents R&D teams from locking onto defect sources early in the process. Additionally, Silicon Photonics components are extremely sensitive to temperature. If microscopic, invisible thermal sources within the module are not detected before packaging, it can lead to the scrapping of costly advanced process chips post-packaging, severely impacting yield and cost.

Technical Value: Replacing Vague Speculation with “Visualized Data”

Through this collaboration, Enlitech has assisted industry partners in establishing comprehensive optoelectronic measurement capabilities ranging from component and wafer to module levels. The introduction of the Night Jar™ system delivers three key breakthroughs for CPO verification:

• Optical Loss Visualization for Precise Defect Positioning: Unlike traditional testing that yields only singular values, Enlitech’s solution provides high-resolution optical loss distribution imaging. This technology enables research and engineering teams to directly “see” the location and intensity of optical signal loss within chip structures, transforming debugging from vague empirical speculation into precise data-driven evidence.

• Increased Throughput to Meet Mass Production Demands: Facing the rapid iteration of the AI chip market, traditional optical testing speeds struggle to keep up. Night Jar™ features high-speed scanning and automated measurement capabilities, significantly reducing testing time for individual components, helping clients quickly converge design issues during R&D, and providing sufficient capacity support for future mass production.

• Pre-empting Thermal Risks to Ensure Packaging Reliability: Beyond optical characteristic analysis, the platform supports internal module hotspot detection. Before heterogeneous integration packaging, it assists engineers in identifying potential waveguide drift or performance shifts caused by thermal accumulation, eliminating potential risks at an early stage.

Partnering to Accelerate the Silicon Photonics Ecosystem

Enlitech is dedicated to providing cutting-edge optoelectronic measurement equipment. This collaboration with iST not only validates Enlitech’s technical strength in the Silicon Photonics domain but also demonstrates a shared commitment to solving industry challenges.

Leveraging iST’s profound experience in reliability verification and physical failure analysis combined with Enlitech’s professional technology in optical measurement, the partnership will assist leading global semiconductor and AI chip companies in shortening the time-to-market for CPO products, preparing for the next generation of light-speed computing.
