Abstract |
In this paper, a gradient boosting model is used to analyze the impact of parameter changes in nanosheet field effect transistor (NSFET). The data is extracted by a technical-computer aided design (T-CAD) simulation to learn machine-learning. Among the gradient tree boosting models, the accuracy of XGBoost and LightGBM (LGBM) algorithm were compared, and the importance was also analyzed. Through the combination of T-CAD simulation and machine-learning, the time and cost should be saved for development of semiconductor devices |
