In the conventional continuous transport type processing apparatus, as shown in Fig. 6, the processing liquid such as the developing liquid, the rinsing liquid, and the cleaning liquid is fixed to the top plate portion of the outer cover of the device, and is then treated as a shower from the nozzle. supply. SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] Γ C* ^ -5- (2) 1335616 However, once the rebounded or evaporated treatment liquid adheres to the top plate portion, water droplets are dropped onto the surface of the substrate during processing. If it happens, the adverse effects such as mottled images will occur. Therefore, the present invention has been made in order to solve the above problems, and to provide a substrate processing apparatus which does not require a reduction in processing speed of a substrate and which does not cause development mottle on the substrate.

At this time, the setting position can be the same position on the left and right, or some gaps can be used. Further, the nozzles which are disposed on the left and right while holding the transport line are rotated when the substrate is transported, and are stopped at a position parallel to the transport roller on the transport path of the substrate, and are transported while the substrate is being transported. The supply operation of the treatment liquid such as the rinse liquid is also performed. When the substrate passes, it will rotate back to its original position. There is no need to return the nozzle during continuous processing. Further, the present invention is directed to a process in which a direction in which the axis is orthogonal to the conveyance direction is a long direction by a roller which is formed by a plurality of rollers which are aligned in a direction orthogonal to the direction in which the substrate is conveyed. The liquid supply slit nozzle is configured to move back and forth along the transport direction, and the slit nozzle has a length equal to a length which is approximately equal to a width dimension orthogonal to a transport direction of the transport line of the substrate, and At the time of supply, the substrate is moved upward from the standby position for preventing the liquid droplets from dropping before the substrate passes, and the processing liquid is supplied onto the substrate. In this way, since the nozzle for supplying the treatment liquid such as the developing liquid, the rinsing liquid, and the cleaning liquid supplied to the transport line or the slit nozzle is a rotary type or a movable type, the fixed nozzle is used. In comparison, there is no need to provide a top plate portion in the substrate processing apparatus, so that it is possible to prevent the drop of water droplets from adversely affecting the substrate. [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Here, the first drawing is a general plan view of the substrate processing apparatus according to the present invention, and along the transport line 1 of the substrate (4) 1335616, the developing liquid supply unit 2 and the developer liquid are sequentially disposed from the upstream side. The portion 3, the rinsing liquid supply and recovery unit 4, and the drying unit 5, and the developing solution supply unit 2 and the rinsing liquid supply and recovery unit 4 are each provided with a rotary processing liquid supply nozzle 6, which is provided 6 is rotated on the substrate as shown by the solid line at the time of supply, and stands by at a position directly above the substrate as shown by the broken line when not supplied. The transport line 1 is formed by a plurality of rollers (cylindrical rollers) 7 which are equidistantly spaced apart and arranged in a direction orthogonal to the transport direction of the substrate. This length is set to be longer than the width dimension of the substrate W to be transported, and is synchronously rotated by a motor (not shown). As shown in Fig. 2, among the plurality of rollers 7 disposed in the developing liquid recovery unit 3 or the rinse liquid supply and recovery unit 4, the roller 7a located at the intermediate portion is freely movable up and down, and The roller 7a is provided on the upstream side and the downstream side, and a tubular collecting member (not shown) is provided below the position of about 1/2 of the length of the long side of the substrate. Next, a method of processing the substrate will be specifically described. First, as shown in FIG. 3, when the substrate conveyed by the roller 7 approaches the developing liquid supply unit 2, the nozzle 6 that is waiting on both sides of the transport line 1 starts to rotate and becomes a substrate. The transport direction is almost vertical, and the developer is mounted on the surface of the substrate. Further, as shown in Fig. 4, the nozzles 6 may be placed at different positions along the transport direction by sandwiching the transport line. In addition, as shown in FIG. 5, instead of the rotary nozzle 6, it is also possible to reciprocate m -8 - (5) (5) 1335616 ft ί 沿着 along the transport direction, and the length is sufficient to cover the substrate. When the substrate is close to the developing liquid supply unit 2, the slit nozzle 8 of the width dimension moves horizontally from the standby portion indicated by the broken line in the drawing in a direction opposite to the conveying direction. The developing solution is mounted on the surface of the substrate. After standing for a predetermined period of time, the image is processed by a roller, and then transported to the adjacent developing liquid recovery unit 3 by a roller, and the roller 7a that can be lifted and lowered is placed in the middle of the substrate in the transport direction (longitudinal direction). Stop the substrate. Next, as shown in Fig. 2, the roller 7a is raised. As a result, the center of the substrate is convex, and the mountain shape bent at both ends is curved, and the developer liquid supported on the surface of the substrate flows from both ends. • Thereafter, as shown in Fig. 1, the substrate is transported by the rollers, and is moved until the supply and recovery portion 4 of the rinse liquid is stopped. Next, as shown in Fig. 2, in the supply and recovery portion 4 of the rinse liquid, the nozzle 6 is moved from the standby position to the highest state while the roller 7a is raised and the substrate is bent into a mountain shape. The center of the substrate is supplied with a rinse liquid. The supplied rinsing liquid flows down the substrate surface toward both ends. Finally, the substrate is transported by the rollers toward the drying section 5. In the illustrated example, the configuration in which the roller is moved up and down has been described. However, the roller may be moved up and down, and a rod-shaped or rod-shaped lifting member may be provided between the roller and the roller. Further, the rollers on the upstream side and the downstream side of the rollers at the intermediate position may be lowered to bend the substrate, and the intermediate position may be replaced by the replacement. <Effects of the Invention> -9- (6) 1335616 - As described above, the nozzle of the present invention capable of supplying a treatment liquid such as a developing liquid, a rinsing liquid, or a cleaning liquid provided on a conveying line, or a slit nozzle - It is a rotary or mobile type. Therefore, if it is compared with a fixed nozzle, there is no need to add a top plate portion to the substrate processing device. This prevents dripping of water droplets and adversely affects the substrate.
