backside alignment (using transmitted IR light). The aligner has
soft contact, hard contact, and vacuum contact modes. The tool has a
350 Watt I-line Near UV lamp calibrated to 20 mW/cm^2 intensity at
I-line (365 nm). Additional energy will be present at h-line and g-line
bringing the total NUV exposure intensity to approximately 45 mW/cm2 (uncalibrated).
