Abstract
A developing process for obtaining a resist pattern on a semiconductor wafer includes puddling a developer on a wafer and holding a wafer inclined at a predetermined tilt angle in the puddled condition and repeating alternately stoppage and slow rotation plural times. This can make the central pattern width narrower selectively simply by apparatus adjustment, in case where, otherwise the pattern width of a wafer's central portion becomes wide, thereby achieving an increased pattern uniformity of the wafer and serve as improving the performances.
