[0066] Such as figure 1 As shown, the present invention provides a multi-scenario multi-performance index prediction method for semiconductor production lines, including a production scene quantitative division module, a main prediction network construction module, and a multi-scenario prediction model construction module. The production scene quantitative division module is driven by data, quantitatively maps the production line's WIP value, product average processing cycle, and utilization rate of each equipment, and divides the production line into three scenarios: light load, normal load, and heavy load; the main forecasting network construction module , taking the divided normal load data as sample data, combining the deep neural network algorithm with semiconductor production line performance prediction to construct a prediction network under normal load scenarios; multi-scenario prediction model building blocks: apply the idea of transfer learning to production line pr...
