FABRICATION TOOL CALIBRATION

Original (Chinese)

A method for calibrating a fabrication system including selecting, from multiple recipes, a calibration recipe including a first process parameter for performing a fabrication process on a substrate, including: for each recipe and for two or more substrates, characterization data representative of the fabrication process performed on the two or more substrates using the recipe is received. A second process parameter is determined from the first and second states of the substrates, and a process relationship is determined between the first process parameter and the second process parameter for the recipe. The calibration recipe is selected from the multiple recipes based on the respective process relationships, a threshold variation for the process relationship is determined between the first and the second process parameter; and the calibration recipe and the threshold variation are provided for calibrating the fabrication system.
