  • Patent number: 8152933
    Abstract: A substrate processing apparatus includes a substrate holding member configured to rotate along with a wafer (W) held thereon and a drain cup (51) configured to surround the wafer (W). A cleaning process is performed by rotating the wafer (W) while supplying a process liquid onto the wafer (W), and then a rinsing process is performed by rotating the wafer (W) in a similar way while supplying a rinsing liquid onto the wafer (W). The rinsing process is performed by first adjusting a rotational speed of the wafer (W) to be the same as the rotational speed used in the cleaning process while supplying the rinsing liquid, and then raising a liquid level of the rinsing liquid inside the drain cup (51) by decreasing the rotational speed of the wafer (W) or increasing a flow rate of the rinsing liquid, and raising a reach position of the rinsing liquid on the outer sidewall of the drain cup (51) by increasing the rotational speed of the wafer (W).
