Abstract
A coating device includes a box-shaped processing chamber. Slits are respectively provided on four side surfaces of the processing chamber. A box-shaped housing is provided so as to surround the processing chamber. A space is formed between the processing chamber and the housing. A fan filter unit for forming downflow in the space is provided on the top of the housing. Air supplied to the fan filter unit is cleaned by the fan filter unit, and is supplied to the space. The air supplied to the space is supplied to the processing chamber through each of the slits in the processing chamber. This causes a twister-shaped air current to be generated within the processing chamber.
