Market Overview

The market is expanding alongside global semiconductor capacity additions and node shrink roadmaps. With dozens of new fabs planned or under construction through the next decade, demand for advanced in-line metrology and process control tools is rising steadily. OCD measurement systems are now deeply integrated into advanced logic and memory manufacturing flows, supporting tighter tolerances and complex multi-pattern structures.

Advanced Node Development
Migration to 7nm, 5nm, and more advanced nodes requires ultra-precise dimensional measurement and profile control. OCD systems provide non-destructive, high-throughput metrology needed for these process generations.

Skilled Metrology Workforce Shortage
Operation and calibration of advanced OCD systems require deep expertise in optics, materials science, and semiconductor physics. A shortage of trained professionals is creating deployment and scaling bottlenecks across fabs.

Accuracy Limits at Sub-5nm Dimensions
At extremely small geometries, measurement reliability faces physical and modeling limits. Quantum and material interaction effects introduce variability, increasing recalibration needs and operational complexity.

Competitive Landscape

Mergers and portfolio consolidations have also shaped the landscape, strengthening end-to-end process control offerings.
