  • Patent number: 10134610
    Abstract: After a development liquid on a substrate is washed away with a rinse liquid, the rotational speed of the substrate is reduced, so that a liquid layer of the rinse liquid is formed over a top surface of the substrate. Thereafter, the rotational speed of the substrate is increased. The increase in the rotational speed of the substrate causes a centrifugal force to be slightly greater than tension, thereby causing the liquid layer to be held on the substrate with the thickness thereof in its peripheral portion increased and the thickness thereof at the center thereof decreased. Then, gas is discharged toward the center of the liquid layer from a gas supply nozzle, so that a hole is formed at the center of the liquid layer. This causes tension that is balanced with a centrifugal force exerted on the peripheral portion of the liquid layer to disappear. Furthermore, the rotational speed of the substrate is further increased while the gas is discharged. Thus, the liquid layer moves outward from the substrate.

  • Patent number: 9687886
    Abstract: A method and apparatus capable of eliminating occurrence of a development failure when a DI water discharge nozzle 20 is scanned to dry a substrate by spinning. A substrate is held in a horizontal posture by a spin chuck and rotated about a vertical axis by a rotation motor, and when an outlet of the nozzle is scanned from a position opposed to a center of the substrate W to a position opposed to a circumferential edge while a cleaning solution being discharged, immediately after the nozzle has started to move, only one dried core is produced in the vicinity of the center of the substrate, and thus production of not less than two dried cores in the vicinity of the center of the substrate is prevented. The dried region is spread all over the surface of the substrate.

  • Patent number: 9477162
    Abstract: A substrate processing apparatus comprises an indexer block, an anti-reflection film processing block, a resist film processing block, a development processing block, a resist cover film processing block, a resist cover film removal block, a cleaning/drying processing block, and an interface block. An exposure device is arranged adjacent to the interface block in the substrate processing apparatus. The exposure device subjects a substrate to exposure processing by means of an immersion method. In the edge cleaning unit in the cleaning/drying processing block, a brush abuts against an end of the rotating substrate, so that the edge of the substrate before the exposure processing is cleaned. At this time, the position where the substrate is cleaned is corrected.

  • Patent number: 8894775
    Abstract: After a substrate is cleaned, a liquid layer of a rinse liquid is formed so as to cover one surface of the substrate. Then, a liquid supply nozzle moves outward from above the center of the substrate. The liquid supply nozzle is stopped once at the time point where it moves by a predetermined distance from above the center of the substrate. In this time period, the liquid layer is divided within a thin layer region by a centrifugal force, so that a drying core is formed at the center of the liquid layer. Thereafter, the liquid supply nozzle moves outward again, so that a drying region where no rinse liquid exists expands on the substrate with the drying core as its starting point.

  • Patent number: 8218124
    Abstract: After a substrate is cleaned, a liquid supply nozzle moves outward from above the center of the substrate while discharging a rinse liquid with the substrate rotated. In this case, a drying region where no rinse liquid exists expands on the substrate. When the liquid supply nozzle moves to above a peripheral portion of the substrate, the rotational speed of the substrate is reduced. The movement speed of the liquid supply nozzle is maintained as it is. Thereafter, the discharge of the rinse liquid is stopped while the liquid supply nozzle moves outward from the substrate. Thus, the drying region spreads over the whole substrate so that the substrate is dried.

  • Publication number: 20120037593
    Abstract: A substrate processing apparatus includes an anti-reflection film processing block, a resist film processing block, and a resist cover film processing block. In the processing blocks, an anti-reflection film, a resist film, and a resist cover film are formed on a substrate, respectively. Additionally, a film formed at a peripheral edge of the substrate is removed. The film formed at the peripheral edge of the substrate is removed by supplying a removal liquid capable of dissolving and removing the film to the peripheral edge of the substrate during rotation. When the peripheral edge of the film is removed, the position of the substrate is corrected such that the center of the substrate coincides with the center of a rotation shaft.
