Abstract

PROBLEM TO BE SOLVED: To prevent ununiform coating of developer due to bending of the peripheral parts on four corners of substrate, while a square substrate with a square shape is sucked to hold at its rotating central part. SOLUTION: This developing apparatus applies specified treatments to a flat and square substrate W, while its processing plane is kept upward and coats it with a developer. In this case, it is provided with a suction plane for sucking and holding the rotating central part, by which a substrate after development is obtained by rotating the substrate at a high speed and removing the waste developer which becomes unnecessary after the development toward a recovery means, a suction rotational disc 8 which is elevated between a first position for taking in the substrate and a second position for applying the developer and is rotated at a high speed at the second position, an exhaust head 11 of developer for applying the developer uniformly, while it moves on the processing plane, and an air cylinder 22 for driving a support pin 20 so as to be almost flush with the suction plane, and then the supporting pin 20 is elevated up to support the parts of substrate which are not held by suction, so that a uniform coating is made over the entire surface.

In the case of a developing apparatus for developing a semiconductor wafer in each of the above-mentioned processing steps, for example, the circular substrate is exposed to light with the processing surface of the substrate facing upward, and then conveyed to the developing apparatus to attract and hold the circular substrate. Then, an alkaline solution, which is a developing solution, is uniformly applied on the exposed surface, and a high-speed rotation is performed to dissolve a portion other than the exposed portion of the resist film to form a desired pattern. After being shaken off by a centrifugal force toward a certain cup, washed with water, and dried, the development processing of the desired pattern is finished, and the resist film is melted in the etching step to obtain a metal film pattern. Thus, in order to perform the application of the developer and the high-speed rotation, the circular substrate is configured to be suction-held by a suction rotary plate having a suction surface having a diameter slightly smaller than the diameter of the circular substrate, and provided in a robot device. The circular substrate can be taken in and out by a fork and the back surface near the outer peripheral surface of the circular substrate can be washed with water.

On the other hand, a glass substrate used in a liquid crystal display device or the like is a flat rectangular substrate having a rectangular shape, and since the thickness is as thin as 1 mm or less, the glass substrate tends to be bent downward by its own weight. When such a rectangular substrate is suction-held at the center of rotation by using the above-mentioned suction rotary plate, the degree of bending at the edges of the four corners becomes so large that it cannot be ignored. In this state, if the developer is applied, uniform application cannot be performed, and uneven development occurs at four corners. Therefore, it is conceivable to prepare a suction rotary plate having a diameter equal to the size of the diagonal line of the rectangular substrate and hold it by suction. However, with such a configuration, the diameter of the suction holding plate becomes considerably large. As a result, the cup gets bigger,
The developing device provided with the cup becomes very large. Further, it cannot be adopted because there is a problem that a nozzle for washing or drying the back surface of the substrate cannot be provided.

Further, when a chemical solution, pure water, air nitrogen gas, or the like is discharged to the back side of the substrate during the developing process, the nozzle is fixed according to the conventional developing device. Since there was a case where setting could not be performed, there was a problem that unevenness in application and cleaning or unevenness in drying during drying occurred.

Further, in order to allow the drainage collected by the cup to flow evenly into the drainage ditch, approximately 60 through holes having a diameter of about 1 mm are formed in the ring above the drainage ditch. In such a configuration, the resist is fixed to the through-hole, so that the hole needs to be cleaned. This cleaning is quite difficult and takes time, and the disassembly of the cup is unexpectedly troublesome. Further, the flow rate of the drainage cannot be adjusted.
