Abstract:
1. A manufacturing method of a semiconductor device comprising: forming a semiconductor thin film on a substrate; processing the thin film to a predetermined shape; executing an ion implantation process on the thin film processed to the predetermined shape; executing an anneal treatment on the thin film on which the ion implantation process has been executed to create a resistor element; calculating a predicted value of a sheet resistance of the resistor element; and adjusting one or both of a dose amount of ions in the ion implantation process and a treatment temperature in the anneal treatment, wherein the calculating includes one or both of: calculating the predicted value based on a film thickness of the thin film formed in the forming and a film-thickness/resistance function, which shows a relation between a film thickness of the thin film and the sheet resistance; and calculating the predicted value based on a size of the thin film processed in the processing and a size/resistance function, which shows a relation between a size of the thin film and the sheet resistance, and the adjusting includes one or both of: adjusting the dose amount based on a dose-amount/resistance function, which shows a correspondence relation between the dose amount and the sheet resistance, to reduce a difference between an object value and the predicted value of the sheet resistance; and adjusting the treatment temperature based on a treatment-temperature/resistance function, which shows a correspondence relation between the treatment temperature and the sheet resistance, to reduce a difference between an object value and the predicted value of the sheet resistance.
