Patent ID: 7968278

Claim:
A rinsing method for performing a rinsing process on a substrate, after a developing process is performed on a light-exposed pattern disposed thereon, the method comprising, in a following order: a first step of throwing off a developing solution from the substrate after development; a second step of supplying a water-based cleaning liquid onto the substrate, the second step is arranged to supply, as the water-based cleaning liquid, purified water along with the developing solution onto the substrate to perform rinsing on the substrate; a third step of supplying a rinsing liquid onto the substrate without supplying the developing solution to replace liquid remaining on the substrate with the rinsing liquid; and a fourth step of rotating the substrate without out supplying either the developing solution or the rising liquid to expand and throw off the rinsing liquid on the substrate, wherein the rinsing liquid consists essentially of purified water containing a surfactant at a concentration of 10,000 ppm or less, the third step is arranged to supply the rinsing liquid through a rinsing liquid supply nozzle for a supply time of 5 seconds or less, the rinsing liquid supply nozzle has a double tube structure formed of an inner tube and an outer tube such that the inner tube has delivery holes formed on the sidewall and the outer tube has a constriction portion formed at a distal end, and is configured to deliver the rinsing liquid through the constriction portion so as to weaken an impact of a delivery flow of the rinsing liquid, and the fourth step is arranged to include a first period with a lower rotation number and a second period with a higher rotation number set in this order, such that the first period is a period of rotating the substrate at a first rotation number of more than 300 rpm and less than 1,000 rpm for a time of 5 to 15 seconds and the second period is a period of rotating the substrate at a second rotation number of 1,000 to 4,000 rpm for a time of 10 to 20 seconds.
