나. Utility and operation environment requirement
1) Clean compressed air
■ Pressure : 6~10 bar, variation ≤0.5 bar
■ Flow : Continuos flow 10 SL/min, Incidentally up to 70 SL/min
2) Vacuum
■ Pressure : Min. 0.5 bar
■ Capacity : Min. 5 SL/min
■ Connector : 6mm inner diameter (ID), 8mm outer diameter (OD) hose
3) Temperature : 18 ~ 24 ℃, stability ±1℃
4) Humidity : 30 ~ 50 % during operation, variation ±5%
5) Cleanness : class 1000 or under
6) Electrical Power requirement : 230 VAC (50/60Hz), Single phase, 20A

다. Safety
1) Emergency stop: system shut down by pushing Emergency stop button
2) Door open sensor: user cannot start to exposure while the sample loading door is open. If user opens the sample loading door while the system is initializing the stages or is operating exposure, system turns off the light source and stops all the stages.
