Abstract: A substrate liquid processing apparatus includes an inner tub 34A having a top opening and storing a processing liquid therein; an outer tub 34B provided outside the inner tub; a first cover body 71 configured to move between a closing position where a first region of the top opening is closed and an opening position where the first region is opened; and a second cover body 72 configured to move between a closing position where a second region of the top opening is closed and an opening position where the second region is opened. The first cover body has a bottom wall 711R and a sidewall 712R extended upwards therefrom, and the second cover body has a bottom wall 721R and a sidewall 722R extended upwards therefrom. Further, when being placed at the closing positions, the sidewalls closely face each other with a gap G having a height H.

Abstract: A substrate liquid treatment apparatus includes an inner tank configured to store a treatment liquid and having an upper opening, an outer tank disposed outside the inner tank, and a lid movable between a close position for closing the upper opening of the inner tank and an open position for opening the upper opening of the inner tank. The lid includes a main portion that covers the upper opening of the inner tank when the lid is positioned at the close position, and a splash shielding portion connected to the main portion. When the lid is positioned at the close position, the splash shielding portion extends from a position higher than an upper end of a side wall of the inner tank adjacent to the splash shielding portion to a position which is lower than the upper end of the side wall and which is on the outer tank side of the side wall.

Abstract: A substrate processing apparatus according to an embodiment includes a substrate processing tank, a processing liquid supply nozzle, and a pressure regulating plate. The processing liquid supply nozzle is provided in a lower portion within the substrate processing tank, and ejects the processing liquid from a plurality of ejection ports. The pressure regulating plate is provided between the processing liquid supply nozzle and the substrate in the substrate processing tank and has a plurality of holes through which the processing liquid flows. The pressure regulating plate is configured to adjust the inflow pressure of the processing liquid ejected from the processing liquid supply nozzle. In addition, the pressure regulating plate includes ribs that protrude from a processing liquid supply nozzle side surface thereof so as to partition the processing liquid supply nozzle side surface into a plurality of partitioned regions.
