Semiconductor metrology system Iris™ series

The Iris series of tools, which include the Iris C1, T1 and R1 models, enable process control across a broad range of applications in high volume manufacturing with excellent performance as well as cost-of-ownership. Product Overview The Iris series is targeted to provide our customer the best cost-of-ownership with a dedicated application-specific optical configuration for HVM applications in semiconductor manufacturing. The Iris C1 system combines a proprietary spectroscopic ellipsometry solution from the Atlas® family with Onto Innovation’s industry leading AI-Diffract™ OCD analysis software, enabling high precision control of every critical semiconductor process step. The system incorporates a dual-arm robot, high-precision stage and high-speed focus system. The system also features advanced pattern recognition, improved thickness reproducibility and throughput. The N2000™ software interface and advanced automation are compliant with standards adopted by SEMI and other organizations. The Iris system and AI-Diffract solution provides insight of complex structure profiles across etch, clean, deposition, CMP and thin films. The Iris T1 is a spectroscopic ellipsometer system that provides accurate, repeatable in-line thickness and optical constant measurements of single and multi-layer dielectric films for fab-wide applications. Built on the same field-proven Atlas platform, the Iris T1 system leverages the most recent advances in optics and algorithms, making it best-in-class for performance and cost-of-ownership. The SEMI/CE compliant N2000™ software interface enables recipe sharing between the Iris series of tools.
