Defect Inspection and Review
KLA’s defect inspection and review systems cover the full range of yield applications within the chip and wafer manufacturing environments, including incoming process tool qualification, wafer qualification, research and development, and tool, process and line monitoring. Patterned and unpatterned wafer defect inspection and review systems find, identify and classify particles and pattern defects on the front surface, back surface and edge of the wafer. This information allows engineers to detect, resolve and monitor critical yield excursions, resulting in faster yield ramp and higher production yield.
