概要（Overview）

Based on a common HBLS optical design derived from our seventh generation Atlas platform and best-in-class deep ultraviolet (DUV) optics, the Iris R1 system offers maximum sensitivity and accuracy to CMP process excursions and enables device makers to establish APC control solutions with high-accuracy feedback. With SpectraProbe and NanoDiffract analysis solutions enabling direct measurements within device and active areas, users are now able to monitor minor process excursions and optimize their processes for higher yields.
