  • Patent number: 7431038
    Abstract: The flow of a processing liquid poured onto the surface of a substrate at a standstill to process the substrate from the surface to the back surface of the substrate is suppressed to achieve satisfactory cleaning. When a processing liquid is poured onto a substrate held in a horizontal position by a substrate holding unit to carryout a predetermined process, for example, a cleaning liquid is discharged through a discharge opening corresponding to the entire circumference of the back surface of the substrate before pouring the processing liquid onto the surface of the substrate, and the cleaning liquid discharged on the back surface of the substrate and a liquid flowing from the surface to the back surface of the substrate are sucked through a suction opening corresponding to the entire circumference of the back surface of the substrate and included in a first suction means. Thus an outward flow of the cleaning liquid is produced on the back surface of the substrate.

  • Patent number: 7387455
    Abstract: Rinsing nozzles 310a to 310e are moved on a wafer W while they are discharging rinsing solution 326. At that point, discharging openings 317a to 317e are contacted to developing solution 350 coated on the wafer W or rinsing solution 326 on the wafer W. Thus, the impact against the wafer W can be suppressed. As a result, pattern collapse can be prevented. In addition, a front portion of the developing solution 350 can push away the developing solution 350.

  • Publication number: 20060086460
    Abstract: In the present invention, an outer peripheral plate is provided in a manner to surround a held substrate. A small gap exists between the outer peripheral plate and the outer peripheral portion of the substrate. Gas blowout ports are formed on the upper surface of an inner cup on the rear face side of the substrate. During cleaning of the substrate by a cleaning solution supplied onto the substrate, a gas is blown out from the gas blowout ports to form a gas flow that flows from the rear face side of the substrate and passes by the lower side of the gap outward to the outer peripheral plate side. The liquid such as the cleaning solution leaking through the gap is swept outward by the gas flow and flows along the rear face of the outer peripheral plate to be drained. According to the present invention, the liquid can be prevented from running around to the rear face side of the substrate during developing treatment.

  • Patent number: 6551400
    Abstract: A solvent of a resist solution is dropped from a solvent supply nozzle onto the surface of a semiconductor wafer held by a spin chuck. The semiconductor wafer is rotated by the spin chuck to spread the resist solution over the entire surface of the semiconductor wafer W. Simultaneously, the resist solution is dropped from a resist solution supply nozzle onto the semiconductor wafer and spread following the solvent. During the processing, the processing space is isolated from the outer atmosphere by closing a lid of a processing vessel and a sprayed solvent is supplied into the processing space. The processing space is thus filled with the mist of solvent. In the processing space supplied with the solvent, evaporation of the solvent from the resist solution is suppressed. A film of the resist solution is formed with a uniform film thickness to the edge of the semiconductor wafer W.
