Abstract:
An air curtain system for forming an air curtain dividing two processing spaces and for spraying gas on a substrate to remove any impurities remaining on the substrate, the air curtain system, comprisinga gas supplier for supplying gas;a main body having a gas inlet passage for receiving gas from the gas supplier, a gas flow space defined within the main body and communicating with the inlet passage, and a slit extending from the gas flow space;an air distributor supported within and across the gas flow space downstream from the gas inlet passage, the air distributor distributing the gas to be sprayed uniformly toward the entire substrate through the slit; andan inpurity remover to primarily remove impurities form the substrate, the impurity remover being mounted on the main body and arranged adjacent to the slit, whereby the impurities on the substrate are sequentially removed by the impurity remover and then by the gas sprayed from the slit of the main body.
