ABSTRACT:
A liquid processing apparatus includes a substrate holding member configured to rotate along with a substrate held thereon in a horizontal state; a rotary cup configured to surround the substrate and to rotate along with the substrate; a liquid supply mechanism configured to supply a process liquid onto at least a front surface of the substrate; and an exhaust/drain section configured to perform gas-exhausting and liquid-draining out of the rotary cup; and a guide member disposed to surround the substrate, having an upper surface to be substantially continued to the front surface of the substrate, and configured to rotate along with the substrate holding member and the rotary cup, such that a process liquid supplied onto the front surface of the substrate and thrown off from the substrate is guided by the upper surface of the guide member from the rotary cup to the exhaust/drain section.
