Abstract
A coating treatment method includes: a first step of rotating a substrate at a first rotation number; a second step of rotating the substrate at a second rotation number being slower than the first rotation number; a third step of rotating the substrate at a third rotation number being faster than the second rotation number and slower than the first rotation number; a fourth step of rotating the substrate at a fourth rotation number being slower than the third rotation number; and a fifth step of rotating the substrate at a fifth rotation number being faster than the fourth rotation number. A supply of a coating solution to a central portion of the substrate is continuously performed from the first step to a middle of the second step or during the first step, and the fourth rotation number is more than 0 rpm and 500 rpm or less.
