EM-6729B and EM-6729-0,25 Automatic mask inspection systems |
|
|
|
EM-6729B and EM-6729-0,25 systems are designed for automatic inspection of reticles and work photomasks having transparent and opaque defects: pindots, pinholes, protrusions, mouse bites, shorts between features, breaks, corner roundings, size shifts, half-tone defects, etc.
The automatic defect inspection is realized through a die-to-database comparison method. After completion of inspection cycle, the defect list is formed and the operator can observe the defects on the display screen.
