The Flat and Notch Finding System is a type of equipment used in the semiconductor industry for the inspection and analysis of wafers. The system identifies the orientation flat or notch on the wafer, which serves as a reference point for dicing and other processing steps. The system typically uses a combination of visual and automated inspection methods to accurately locate the flat or notch on the wafer, ensuring consistent and accurate results. This helps to minimize processing errors and improve the overall yield of the semiconductor production process.
