The Applied Materials Complus 4 T is a darkfield defect inspection system. The Complus 4 T supports 12-inch wafers. The Complus 4 T is categorized as a Metrology & Inspection tool.[1][2]
What it is
General reference — not yet source-verifiedA darkfield defect inspection system detects surface anomalies by optical inspection rather than by device electrical test. Darkfield inspection tools are used to find particles, scratches, and other surface defects on wafers before later manufacturing steps depend on those surfaces.
How it works
General reference — not yet source-verifiedA darkfield inspection system illuminates the wafer at an angle that suppresses specular reflection from the surface. A defect scatters light into the collection optics, which allows the tool to detect and locate irregularities that stand out from the background surface.
An inspection tool of this class typically scans the wafer surface in a patterned or rasterized manner. The system compares detected scattering signals against threshold criteria so that defect candidates can be flagged for review or process monitoring.
Where it fits in the process flow
General reference — not yet source-verifiedA darkfield defect inspection system fits into wafer metrology and inspection flow between process steps that can introduce contamination or surface damage and later steps that require a clean surface. The tool supports process monitoring and excursion detection on production wafers.
