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.
