Atlas® G6 System
The Atlas G6 system is an OCD and thin film metrology tool engineered for the most advanced logic and memory devices. Designed to meet the demands of next-generation AI applications and beyond, it delivers enhanced optics, AI-driven recipe development, and tighter tool matching for superior process control.
Product Overview
As semiconductor manufacturers push into next-generation GAA nodes and next-gen HBM and vertical DRAM architectures, process control requirements are tightening. Smaller nanosheet structures and denser DRAM cells demand higher measurement precision, faster recipe development, and tighter tool-to-tool matching.
The Atlas® G6 system is engineered to meet these challenges with a new optics design that improves signal-to-noise ratio, spectral stability, and measurement precision. Enhanced software algorithms and data management tools deliver better fleet-wide spectra matching, while a new data channel and next-generation model-guided machine learning in Ai Diffract™ software enable faster, more robust recipe development. A smaller optical spot size ensures accurate measurements on today’s most compact DRAM structures.
Fully integrated with Onto Innovation’s Discover® ecosystem, the Atlas G6 system empowers fabs with predictive process control and smart manufacturing capabilities—accelerating yield and time to market for the industry’s most advanced devices.
