Nanotechnology Now - Press Release: Nanometrics Delivers 100th: Atlas III System for Advanced Process Control Metrology Atlas III: Systems are qualified and in production for advanced devices in DRAM, 3D-NAND and Foundry/Logic

'We are excited to achieve this milestone with the Atlas III, just two years after we started shipping systems,' stated Dr. Pierre-Yves Lesaicherre, president and chief executive officer of Nanometrics. 'The rapid adoption and ramp of the Atlas III reflects Nanometrics' technology leadership as the pioneer of optical critical dimension (OCD) metrology and the close partnerships we have with our key customers. The Atlas III provides our customers additional insight to control and debug their most complex device manufacturing processes and is instrumental to the ramp of leading-edge devices.'

'The Atlas III is the fastest-ramping product in Nanometrics' history,' commented Sudhakar Raman, vice president and general manager of the automated metrology systems business unit at Nanometrics. 'The Atlas III is the third generation in the Atlas family, first introduced in 2004, and is our flagship automated system supporting advanced OCD and thin films metrology with our proprietary ellipsometry and reflectometry technologies. The Atlas III delivers best-in-class precision and repeatability at faster overall system throughput, supporting a broad variety of process control applications. These systems are qualified at the top five 3D-NAND manufacturers, two of the largest DRAM manufacturers, and leading foundry customers for sub-10nm devices.' When combined with NanoDiffract, the Atlas III enables high-fidelity metrology on the most complex three-dimensional structures. When utilizing SpectraProbe, the Atlas III provides unique insight into on-device and in-die control for advanced yield learning and process optimization.
