Abstract:
1. A pattern forming apparatus, comprising: a substrate holder which holds a substrate; a nozzle which has a discharge port which is capable of continuously discharging an application liquid which contains a photo-curing material; a light emitter which emits light toward the application liquid discharged from the discharge port, wherein the light emitter moves in a vertical direction relative to the nozzle; and a moving mechanism which moves the nozzle in a predetermined scan direction along and relative to a surface of the substrate which is held by the substrate holder while moving the light emitter, as if to follow the nozzle, along and relative to the surface of the substrate in the scan direction, wherein as the nozzle which is moved by the moving mechanism relative to the substrate arrives at a predetermined application end position, the nozzle stops discharging of the application liquid from the discharge port and the moving mechanism moves the nozzle away from the surface of the substrate in a direction that a gap in the vertical direction between the nozzle and the substrate increases while maintaining a gap in the vertical direction between the light emitter and the surface of the substrate constant, and after the nozzle moves away, the moving mechanism moves the light emitter relative to the substrate in the scan direction, whereby the light emitter irradiates light to a terminating end of the application, liquid which is terminated by the discontinued discharging from the discharge port.
