Abstract:
1. A substrate liquid processing apparatus comprising: a placement table configured to hold a substrate; a rotary driving unit configured to rotate the placement table; a liquid supply unit configured to supply a liquid to the substrate placed on the placement table; an outer upper liquid guide cup, a central liquid guide cup, and an inner lower liquid guide cup which are disposed in this order from the top and are configured to guide downward the liquid scattering from the rotating substrate being placed on the placement table; and a driving mechanism configured to move up and down the upper liquid guide cup, the central liquid guide cup, and the lower liquid guide cup, wherein the driving mechanism is connected to the central liquid guide cup and the upper liquid guide cup is moved upward in a manner of being supported by the central liquid guide cup, and wherein while the driving mechanism moves upward the central liquid guide cup, the central liquid guide cup moves upward independently and spaced apart from the upper liquid guide cup and the lower liquid guide cup in a partial range of an upward movement range and moves upward together with the upper liquid guide cup supported by the central liquid guide cup in another partial range of the upward movement range.
