…virtually maintenance free. WAFER INSPECTION Wafer inspection is also performed by scanning one or more focused laser spots over the test surface. However, wafers are highly reflective, so only reflected or scattered light can be captured. In addition, when examining patterned wafers, light is scattered by…

…of surface being examined (pattern or unpatterned wafer), and the type of defect being sought (pattern defects, contaminants, voids, etc.). Broadly, laser wafer inspection schemes can be classed as either "brightfield" or "darkfield," where the wafer appears bright with defects showing as dark areas…

…technology for inspecting unpatterned wafers often lags a generation behind the technology used for lithography. This means that the inspection wavelength need not be identical to the size of killer defects, particularly if those defects manifest either as foreign material on the wafer or as a raised…
