Classification: CPC G  H | IPC G

Claim 0:
1. 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,, wherein
the (D) comprises:
(c) rotating the substrate while supplying the rinse liquid to the substrate on which the hydrophilic layer has been formed; and
(d) after the (c), rotating the substrate in a state of not supplying the rinse liquid, to dry the substrate,
the (d) comprising:
(m) accelerating the rotation speed of the substrate while supplying gas so as to form a recessed part in a film of the rinse liquid at a center on the substrate to spread the recessed part; and
(n) after the (m), decelerating the rotation speed of the substrate according to a spread of the recessed part and maintaining the decelerated rotation speed for a predetermined time.
