Zusammenfassung:A system and method for inline detection of defects on a semiconductor wafer surface during a semiconductor device manufacturing process is disclosed herein. In one embodiment, a method includes: automatically transporting the wafer from a first processing station to an inspection station; scanning a wafer surface using a camera in the inspection station; generating at least one image of the wafer surface; analyzing the at least one image to detect defects on the wafer surface based on a set of predetermined criteria; if the wafer is determined to be defective, automatically transporting the wafer from the inspection station to a stocker; and if the wafer is determined to be not defective, automatically transporting the wafer to a second processing station for further processing in accordance with the semiconductor device manufacturing process.
