    摘要: For a substrate having a diameter of 300 millimeters and a main surface on which a lot of pattern elements standing upright are formed, a processing using a processing liquid is performed on the main surface. After the processing using the processing liquid, a filler solution is applied onto the main surface. In the application process of the filler solution, pure water is supplied onto the main surface which faces upward while the substrate is in a horizontal state, and a liquid film of the pure water which covers the main surface and has a thickness not larger than 5 micrometers is formed by rotating the substrate. Then, the filler solution containing a water-soluble filler is supplied onto a center portion of the main surface while the substrate is rotated at the number of rotation not smaller than 300 times and not larger than 500 times per minute.
