Predicting defect density of semiconductor wafer is a critical process in the manufacturing of semiconductor products since it has direct effect on product yield, cost-effectiveness and effort in process optimization. In this research work, we present a data-driven ensemble learning framework to predict defect density accurately by combining the process parameters, inline metrology, and environmental explanatory obtained through the process. It has a main four-step structure, preprocessing of data, feature engineering, training of a model, and evaluation. Each individual lot of wafers at a 300mm semiconductor fabrication facility was collected as the set of 150,000 data points that were selected, and advanced data-reduction and exploration methods have been used to combat the high dimensionality and complexity of manufacturing data with principal component analysis (PCA) and stacking ensembles. According to the experimental results, the stacking ensemble model has provided better results as compared with singular learning schemes, such as Random Forest, XGBoost and LightGBM, where its R 2 value is 0.92 and an RMSE of 0.038. The feature importance analysis identified lithography overlay error, the change of the deposition temperature, and humidity in the environment, as having the highest impact on defect density. The study will develop a strong predictive model that will facilitate active process variability and minimize defects and ultimately overall semicon moderately processes efficiency.
