Case Studies
Atomscale accelerates time-to-insight for atomic-scale engineering across a broad range of material systems.
Case Study
Composition metric accuracy
Predicted versus XPS-measured composition across 24 process conditions. The customer's best existing metric scatters widely around the ideal line at an RMSE of 1. The Atomscale metric tracks the ideal line across the whole process window at an RMSE of 0.1.

Case Study
Process similarity trace
Material state over time after a setpoint change. Both actual inputs overshoot the target and ring, while the ideal response settles at the target. The measured system lag is 75% longer than the assumed lag.
