Patent ID: 8741070

Claim:
A liquid processing method of processing an object to be processed which includes a main body, a plurality of convex portions protruding from the main body and a base surface formed between the convex portions on the main body, the method comprising: supplying a chemical liquid to the object to be processed; supplying a rinsing liquid to the object to be processed thereby removing the chemical liquid from the object to be processed; after removing the chemical liquid from the object to be processed, processing a surface of the object to be processed with a chemical liquid containing ozonized water such that the base surface of the object to be processed which is made of a Si-based water-repellent material becomes selectively hydrophilic, and processing the surface of the object to be processed with a water-repellent liquid such that the surfaces of the convex portions each of which is made of a metallic hydrophilic material become selectively water-repellent; supplying a rinsing liquid to the object to be processed which has been subjected to the surface processing; and removing the rinsing liquid from the object to be processed thereby drying the object to be processed.
