Claim 8:
9. A developing treatment method for performing a developing treatment on a resist film on a substrate, the developing treatment method comprising:
(A) supplying a developing solution to the substrate and developing the resist film to form a resist pattern;
(B) supplying a water-based cleaning liquid to the developed substrate to clean the substrate with the water-based cleaning liquid;
(C) applying an aqueous solution of a water-soluble polymer to the substrate cleaned with the water-based cleaning liquid to form a hydrophilic layer having a hydrophilic property on a surface of the substrate; and
(D) cleaning the substrate on which the hydrophilic layer has been formed, with a rinse liquid,
the (B) comprising:
(a) accelerating a rotation speed of the substrate; and
(b) after the (a), decelerating the rotation speed of the substrate until a start of the (C), and

the (C) comprising:
(e) rotating the substrate while supplying the aqueous solution of the water-soluble polymer to the substrate cleaned with the water-based cleaning liquid; and
after the (e), maintaining a rotation of the substrate in a state of not supplying the aqueous solution of the water-soluble polymer, wherein

the aqueous solution of the water-soluble polymer and the rinse liquid are acidic, and wherein
an execution time of the maintaining the rotation is longer than an execution time of the (e).
