TOOL DRIFT COMPENSATION WITH MACHINE LEARNING
20230296987 · 2023-09-21 ·

Methods and systems for predictively determining tool drift in a digital lithography tool for early warning, and/or adjusting the tool in-situ to mitigate the effects of drift. Drift is measured during manufacturing by measuring alignment marks from eye-to-eye a bridge-to-bridge, among other methods. Measured drift is decomposed into three components: trend—trending drift over time, increment—rate of change of drift over time, and remaining—the difference between the drift, the trend, and the increment. Each component is provided to a machine learning engine, that predicts the next measurement of each component. Predicted measurements may be provided to the tool for use as adjustment parameters to modify how an eye module shoots a pattern onto a substrate, and/or as an early warning when predicted parameters are outside of a desired processing parameter window.
