ABSTRACT:
A substrate placed on a movable table movable in the X-direction and a spreading nozzle swingable in the Y-direction are relatively moved such that an extended line of the center axis of the spreading nozzle draws a zigzag trace on the substrate. During this relative movement, spacers are spread from the spreading nozzle while the substrate is sequentially discharged by a discharging bar in the moving direction of the substrate by a discharging bar. When the spreading nozzle passes each of folded portions where the trace is folded, the spread amount of the spacers from the spreading nozzle is reduced.
