PURPOSE:To make the size of the pattern of photoresist uniform in the surface of a wafer and to remove material yielded in development sufficiently, by fixing and holding a wafer so that the surface of the photoresist faces downward, and making it possible to move the wafer in a container containing specified liquid such as developer. CONSTITUTION:A discharge port 5 is closed, and developer is stored in a cup 1. A wafer fixing means 2 is moved downward, and a wafer 10 is immersed in the developer in the cup 1. A surface 11 of the photoresist of the wafer 10 is uniformly contacted with the developer, and the photoresist is developed. Then the discharge port 5 is opened so as to discharge the developer, and the discharge port 5 is closed. Pure water is injected through a nozzle 4 and stored in the cup 1. The wafer fixing means 2 is lowered as in the case of the developer. The wafer 10 is washed with the pure water. The discharge port 5 is opened again, and the pure water is discharged. The wafer fixing means 2 is lifted upward and turned, and the surface of the wafer 10 is dried. The entire surface of the photoresist is uniformly contacted with the developer. The photoresist pattern is uniformly formed. Material yielded in developing can be readily removed.

[Problems to be Solved by the Invention] According to the conventional photoresist developing apparatus described above, when the developer is discharged from the developer nozzle 3 onto the surface 11 of the photoresist on the wafer 10, the developer is discharged onto the wafer 10. Since the surface 11 of the photoresist is not uniformly applied, the dimensions of the photoresist pattern formed by development become non-uniform within the surface of the wafer 10, and the surface of the wafer 10 on which the photoresist pattern is formed is uneven. Since the photoresist is facing upward, there is a problem in that substances insoluble in the developer generated from the photoresist during development are not sufficiently removed by rinsing with pure water.
