Machine learning-based material optimization is often performed as a black box process, making it difficult to explain the rationale behind the optimized process conditions. In this study, the amorphous silicon nitride (a-SiN) deposition parameters for an optimal GaN high electron mobility transistor device were determined by also considering the interpretability by correlation analysis and causal discovery.
