Defect Inspection Module
EB40 - Onto Innovation
The Class 1 certified E40 and B40 modules (available separately or combined in one module) 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.
