Abstract:
A substrate processing method of processing a substrate using a block copolymer containing a hydrophilic polymer and a hydrophobic polymer, the substrate processing method includes: a block copolymer coating step of applying the block copolymer onto the substrate on which a predetermined projecting and recessed pattern is formed, to form a coating film of the block copolymer; a polymer separation step of phase-separating the block copolymer into the hydrophilic polymer and the hydrophobic polymer; a polymer removal step of selectively removing the hydrophilic polymer from the phase-separated block copolymer; and after the block copolymer coating step and before the polymer removal step, a film thickness reduction step of reducing a film thickness of the coating film of the block copolymer.

Claim (Index 3):
The substrate processing method according to  claim 1 ,\n wherein in the film thickness reduction step, the film thickness of the coating film of the block copolymer is reduced by: irradiating the substrate in an atmosphere containing an oxygen gas with an ultraviolet ray and exposing the substrate on which the coating film of the block copolymer is formed to an active oxygen atmosphere; and thereafter performing plasma processing with oxygen gas-containing plasma on the substrate on which the coating film of the block copolymer is formed.
