N2 purge in between the wafer and mask and wafer.
UV expose and the Nano imprint aspect ratio can be 10:1 with 300 um thickness PR (option item).
Operation system:
PLC or computer with Touch panel control interface, plus the operator control switch box.
Pneumatics & electronics valve control system
Timer: 0.1-999 sec / Emergency StopMask Vacuum : 0~ 25” Hg

Auto leveling in between Mask vs. substrate
Auto Z axis: auto gape adjustment—only input the gape value in between mask and wafer—i.e. 100um, then optical encoder and step motor system will automatically do the leveling and also gape tuning.
System power (light source, illuminator, power supply ,) integrate at same panel
Control the Nano Imprint pressure by motor and also Air Cylinder (option item).
Vibration proof table (option):
1)Integrate 4 vibration pads with Al. or SUS frame to support Aligner
2) Option with the granite plate for Vibration isolation is available.
3) Integrate TMC or New Port vibration proof table with Aligner
- Could integrate auto light shutter Performance:
