The E25/B20 combines both edge and backside inspection into one enclosure. It retains all the capabilities of the proven E25 and B20 System in one small footprint. The Class 1 certified system can automatically detect defects on the entire edge, from zone 1 to 5, and the entire backside. The ability to inspect the entire backside allows for faster root-cause analysis of zone 5 defects since such defects can migrate from the wafer interior.
