Abstract:
1. A discharge apparatus for discharging droplets of fluid material on a substrate that has at least one target discharge area, the discharge apparatus comprising: a stage on which the substrate is adapted to be placed such that the target discharge area is positioned to extend in a X-axis direction; a first discharge head unit having a plurality of first discharge heads, each of the first discharge heads including at least one first nozzle row having a plurality of first discharge nozzles, all of the first discharge nozzles disposed in the first nozzle heads being arranged on different X-axis direction positions so as not to overlap each other when viewed in a Y-axis direction, the Y-axis direction intersecting with the X-axis direction; a second discharge head unit having a plurality of second discharge head, each of the second discharge heads including at least one second nozzle row having a plurality of second discharge nozzles, the second discharge head unit being separated from the first discharge head unit in the Y-axis direction by a first distance; and a scanning unit for moving at least one of the stage and the discharge head unit in the Y-axis direction with respect to the other, when any one of the plurality of first discharge nozzles is at an area above the target discharge area due to the relative movement between the stage and the discharge head unit, the first nozzle being configured to discharge a first droplet of the fluid material to the target discharge area, when any one of the plurality of second discharge nozzles is, due to the relative movement in the Y-axis direction, at the area above the target discharge area to which the first droplet has been discharged, the second nozzle being configured to discharge a second droplet of the fluid material to the target discharge area.
