概要（Overview）

The Nanometrics Atlas™ is an advanced metrology system that can accommodate both 200 or 300 mm wafer metrology. It features a dual-arm robot, high-precision stage, and high-speed focus system. The system also boasts robust pattern recognition, improved thickness reproducibility, and superior throughput. The N2000 software interface and advanced automation are compliant with industry standards, and the NanoNet feature provides system-to-system matching and seamless recipe transferability. The Atlas can be configured with a combination of metrology modules, including Spectroscopic Reflectometer (SR), Spectroscopic Ellipsometer (SE), Optical Critical Dimension (OCD), Diffraction Based Overlay (DBO), and Wafer Stress/Bow.
