TrueADC® Software
TrueADC software enhances defect classification accuracy and efficiency by combining deep learning, real-world defect modeling, and intuitive workflows—reducing manual review and improving decision-making across all wafers and surfaces.
Product Overview
TrueADC software sets a new standard in defect classification by combining advanced analytics with intuitive usability. Seamlessly integrated with Onto Innovation’s AOI tools and Discover platforms, TrueADC software enhances inspection value through a proprietary hybrid decision-making process across all wafers and surfaces.
With over 70% reduction in manual review, TrueADC software intelligently flags low-confidence defects as “unknown” to avoid misclassification. Its dynamic defect library method uses real defect examples—unlike traditional ADCs that rely on approximations—delivering more accurate and efficient results.
Supporting adder, repeater, SPR codes, and region-of-interest data, it enables precise tool sampling and binning. Operators can quickly classify new defects without altering recipes, while the software’s multi-engine mode leverages deep learning to reduce overkill and underkill.
From model development to identifying hard-to-isolate defects, TrueADC software empowers engineers with greater clarity, control, and confidence.
Applications
- On-tool with Onto AOI systems
- Inline defect classification
- Dynamic defect library utilization
- Support for advanced defect types

Discover® Patterns Software
Discover Patterns software quickly and easily traces patterns back to yield-killing process issues.
Product Overview
Discover Patterns software combines sort and defect spatial patterns utilizing proprietary machine learning (ML) algorithms, to uncover hidden patterns that would have been otherwise lost. Segmentation allows users to eliminate noise and extract definitive patterns from a larger pattern or a seemingly random array of defects. Wafer stacking enables the handling of faint defect trends to more clearly isolate patterns.
Combining Discover Patterns software with the Discover Defect platform multiplies the value of your defect management infrastructure by intelligently identifying and acting upon known patterns in real time. It marks defects and die affected by patterns for deeper understanding of processes and reduces the need for human intervention.

Highlight all patterns, not just the dominant ones
