The 75th anniversary celebration of ECTC in Dallas showcases a remarkable evolution in advanced packaging technologies, revealing how semiconductor priorities have dramatically shifted. Rather than the relentless miniaturization of the smartphone era, today’s AI-driven applications demand larger packages with more functionality and sophisticated thermal management solutions.
Glass core substrates emerged as the star technology of the conference, with standing-room-only sessions demonstrating the industry’s intense interest in this promising material platform. The excitement is justified – glass offers superior dimensional stability and enables higher-density interconnects than traditional organic substrates. Meanwhile, co-packaged optics generated similar enthusiasm as engineers tackle the monumental challenge of powering AI server racks that consume between 0.5-1 megawatt each, making energy efficiency a critical concern.

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
Applications
- Memory
- Logic
- Foundry
- Compound-Semi
- LED
- Advanced Packaging

StepFAST® Software
An advanced feed-forward lithography software solution for fan-out panel level packaging that enhances yield and throughput by correcting die placement errors through external measurements, predictive analytics and adaptive shot control.
Product Overview
StepFAST® software is Onto Innovation’s advanced lithography software solution tailored for fan-out panel-level packaging, where die placement errors and material instability can significantly impact yield and productivity. StepFAST® software uses a feed-forward adaptive shot approach, integrating high-speed die placement measurements from the Firefly® system and applying real-time corrections to every shot of the JetStep® lithography tool. This external measurement strategy doubles throughput compared to traditional on-tool (self-metrology) methods. The software also incorporates predictive yield analysis, enabling dynamic adjustment of exposure field sizes to balance throughput and overlay accuracy. By automating reticle selection and optimizing field coverage, StepFAST® software ensures efficient panel exposure while minimizing registration errors—from ±50µm down to under ±3µm. With advanced analytics, StepFAST® software transforms lithography into a flexible, high-efficiency process, delivering substantial improvements in yield, throughput, and cost of ownership for panel-level packaging applications.
