Nanometrics Releases NanoDiffract 4

Latest software extends process control capabilities for advanced 3D devices

MILPITAS, Calif., July 10, 2017 (GLOBE NEWSWIRE) -- Nanometrics Incorporated (NASDAQ:NANO), a leading provider of advanced process control systems, today announced the release of NanoDiffract® 4, the latest version of its industry-leading optical critical dimension (OCD) modeling and analysis software with an optimized user interface. NanoDiffract 4 enhances user productivity with added features and options resulting in reduced time-to-solution for the most complex devices. The software is designed to improve modeling and analysis for the latest-generation high-aspect-ratio structures used in DRAM and 3D-NAND, as well as handling the most complex 3D FinFET logic/foundry structures. The NanoDiffract 4 analysis engine coupled with its high-fidelity modeling accuracy greatly improves metrology performance, enabling enhanced in-line sensitivity to critical steps, leading to better factory control.

"Nanometrics' OCD metrology has been broadly adopted by our customers across all device types and key unit operations in R&D and production for its productivity and sensitivity," commented Adrian Wilson, vice president and general manager of the software & analytics business unit at Nanometrics. "Our customers have to manage very narrow process tolerances, and with the latest Diffract 4 they get rapid visibility in-line to control their most challenging processes."

NanoDiffract 4 is in production on the latest Nanometrics Atlas®, IMPULSE® and NanoGen™ systems for thin film and OCD metrology and currently deployed across numerous customer sites for advanced memory and logic/foundry devices. Combined with the company's advanced metrology platforms, the latest NanoDiffract 4 software further extends Nanometrics' comprehensive solutions in process control metrology for the most challenging 3D device structures, including a new SRAM optimizer and 3D-NAND configuration for support of 100+ layers.

For a review of NanoDiffract 4 and the full suite of process control metrology systems, visit Nanometrics at SEMICON West July 11-13, Moscone Center, San Francisco, booth #5844 North hall.
