Transparent film error correction pattern in wafer geometry system
Abstract:
A system includes one or more wafer geometry measurement tools configured to obtain geometry measurements from a wafer. The system also includes one or more processors in communication with the one or more wafer geometry measurement tools. The one or more processors are configured to apply a correction model to correct the geometry measurements obtained by the one or more wafer geometry measurement tools. The correction model is configured to correct measurement errors caused by a transparent film positioned on the wafer.
