MWL200 Wafer Inspection Machine
Smagics' MWL200 wafer inspection machine efficiently and safely handles 6-inch(150mm) and 8-inch(200mm) wafers. Noncontact optical centering minimizes contact during handling to preserve cleanliness and integrity. Integrated 360-degree macroscopic inspection observes both wafer faces without blind spots to identify surface defects and dust. Recipe management stores up to 10 process-parameter sets for rapid product switching, improving throughput and convenience. The system meets SEMI S2/S8 international safety and ergonomics standards for reliable front-end and back-end wafer handling.

Applications
Optical inspection before wafer dicing; automated loading/unloading for pre-dicing Wafer optical inspection
Key Features
High-resolution imaging detects minute defects/structures. Automated transfer and rapid imaging improve throughput. AI and 3D algorithms automatically identify/classify defects, analyze 3D morphology and generate detailed reports for process optimization. Strict quality/reliability validation ensures stable long-duration operation. Compatible with standard microscopes. Expandable LIBS elemental analysis and laser marking/repair. Pre-dicing wafer optical inspection supports 150mm/200mm wafers, thickness 80-1700μm and transparent, translucent or opaque materials. Macroscopic inspection: front surface with 360° rotation at different angles; back center/edge inspection. Microscopic inspection: 5X, 10X, 20X, 50X and 100X objectives, motorized switching, manual/motorized stage (motorized required for AOI). Optional automatic AOI defect detection, 3D profile analysis/measurement, LIBS elemental analysis and laser repair.
