Cohu’s Eclipse platform is specifically engineered to handle complex data center chips utilized in intensive AI compute workloads. The system accommodates high-power graphics processing units (GPUs), central processing units (CPUs), and high-bandwidth memory (HBM) architectures. During the back-end testing phase, high-performance logic and memory devices generate significant heat, requiring advanced thermal control interfaces to prevent thermal runaway while validating chip performance under simulated peak operational loads. The Eclipse system provides the mechanical positioning, contact stability, and precise thermal management required to execute rigorous electrical and operational tests on high-value AI components.
The Neon Metrology Platform and 1-Micron Defect Detection
Complementing physical chip handling is Cohu’s Neon inspection and metrology platform. Specialized for memory chip production, the Neon platform analyzes the physical conditions of advanced memory dies prior to and following chip assembly. The system integrates proprietary AI software algorithms alongside high-resolution infrared vision hardware to inspect internal and surface structural integrity.
By utilizing infrared illumination, the Neon platform can penetrate silicon structures to identify subsurface cracks, voiding, edge chipping, and alignment anomalies. The platform achieves physical resolution capabilities capable of detecting defects as small as 1 micron. In high-density memory stack architectures such as HBM, where micro-defects can compromise an entire multi-chip package, micron-level metrology serves as a primary yield protection mechanism for semiconductor fabricators.
