Researchers have developed a novel virtual metrology approach to predict phototransistor gain using a hierarchical, uncertainty-aware method. This technique is designed for small production datasets, addressing the challenge of lengthy cleanroom times required for physical device measurement. The study decomposes gain variance, revealing significant variation between process runs, and introduces a forward gain predictor, an inverse search for target gain, and a multi-level data-quality assessment.
