WDI Wise Device Inc., a leader in microscopy automation and precision imaging solutions, is transforming semiconductor manufacturing with next generation autofocus sensors and configurable inspection platforms. With over 20 years of engineering expertise, WDI’s solutions enhance wafer metrology, defect detection, and overall fab throughput—helping manufacturers achieve operational excellence, higher production yield, and more efficient process control.

A key differentiator is WDI’s co-engineering development model, which enables seamless integration of autofocus sensors, motion stages, and illumination modules tailored to each customer’s semiconductor inspection workflow. This ensures every system is optimized for real-world production demands, not just off-the-shelf performance, allowing fabs to meet tight tolerances while maintaining high yield, reliability, and long-term operational stability.

At the heart of WDI’s offerings is the PFA-LN (Precision Focus Automation) autofocus sensor, engineered for high-speed automated optical inspection (AOI) and semiconductor metrology. Advanced optical processing, multi-segment data acquisition, and long-term calibration stability allow the PFA-LN to maintain sub-micron focus accuracy—even on patterned or reflective wafers during continuous production—supporting the precise, repeatable measurements modern fabs demand.

WDI’s modular microscopy ecosystem—including SEMI-compliant motion stages, interchangeable objectives, and flexible illumination sources—reduces development overhead, accelerates system validation, and allows manufacturers to scale inspection capabilities efficiently as device geometries shrink and yield requirements increase. Its flexible architecture also enables rapid adoption of emerging inspection techniques, keeping fabs ahead of evolving production challenges.

Looking ahead, WDI is expanding into semiconductor inspection, micro-LED manufacturing, and biomedical markets, cementing its position as a trusted cross-industry partner. Its autofocus and imaging platforms help manufacturers achieve higher yields, improved uptime, and long-term reliability, making WDI Wise Device Inc. a critical enabler of advanced semiconductor production and technological innovation.
