KLA

A macro defect inspection system is used to find visible surface defects and to support inspection workflows on semiconductor wafers. A machine in this class belongs in wafer inspection rather than process modification, and it is used to review patterned or unpatterned wafer surfaces for anomalies.
The KLA INS 3000 Macro Defect can be configured with bright field and dark field illumination. The KLA INS 3000 Macro Defect can also be configured with macro illumination, auto focus, a motorized stage, image capture software, and a PC with Ethernet connectivity.[2]
The KLA INS 3000 Macro Defect can support microscope objective sizes of 2.5X, 5X, 10X, 20X, 50X, and 100X. The KLA INS 3000 Macro Defect can also be configured with a wobbler microscope inspection function.[2]
The KLA INS 3000 Macro Defect is used in wafer inspection workflows after a wafer has received process steps that could introduce particles, scratches, or other visible defects. The KLA INS 3000 Macro Defect supports review and classification of surface issues before the wafer moves to later inspection, analysis, or downstream manufacturing steps.

Macro-defect inspection looks at whole wafers or large areas at low magnification to find defects such as scratches, stains, chips, and large particles. Micro-defect inspection uses high magnification to detect very small sub-micron defects that cannot be resolved by macro inspection. The two methods are complementary.
The system captures images of the wafer surface under controlled illumination and compares different regions, such as adjacent dies or a reference pattern, to identify unexpected changes in reflectivity or topography. Suspect locations are flagged and classified based on their visual signature and coordinates.
Yes, macro-defect inspection systems of this class generally support both patterned and unpatterned wafers. Patterned-wafer inspection uses die-to-die or die-to-database comparisons, while unpatterned-wafer inspection relies on background comparison and defect-detection algorithms adapted to bare surfaces.
Because macro inspection operates at low resolution, very small defects, defects buried below the surface, and defects that do not alter reflected light may be missed. Macro inspection is therefore used as a screening step and is often paired with higher-resolution review tools for confirmation and characterization.
No, systems in this class are used in production as well as research and development, process development, and failure analysis. In R+D settings, macro-defect inspection helps evaluate new processes, qualify materials, and study the origin of yield-limiting defects.
