发明名称 Liquid processing apparatus, liquid processing method and storage medium
摘要 A liquid processing apparatus and method capable of separately collecting first and second processing liquids from each other, and preventing a formation of a defect (such as watermarks and particles) on a target substrate are disclosed. In one embodiment, the liquid processing apparatus includes a substrate holding device, a processing liquid supply device to supply a first processing liquid and a second processing liquid, a rotating cup, an outer discharge portion and an inner discharge portion to respectively discharge the first processing liquid and the second processing liquid received from the first receiving surface of the rotating cup, and a discharge portion switch device to open/close the outer discharge portion. The lower end of the first receiving surface of the rotating cup extends to a lower position than the position of the substrate held by the substrate holding device. The first processing liquid is discharged toward the outer discharge portion when the discharge portion switch device moves up, and the second processing liquid is discharged toward the inner discharge portion 16 when the discharge portion switch device moves down.
