Wafer inspection and sorting machine Rudolph Technologies

The Rudolph Wafer device 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.
