  • Patent number: 8286576
    Abstract: A thermal processing unit of a thermal processor for anti-reflection films includes: a covering nozzle for covering a substrate from above supported by a thermal processing plate and discharging an adhesion enhancing agent to a periphery of a substrate supported by the thermal processing plate; and a vaporization processor for supplying an adhesion enhancing agent in the vapor phase to the covering nozzle. While a substrate placed over the thermal processing plate is being subjected to thermal process, a control part causes the covering nozzle to discharge an adhesion enhancing agent in the vapor phase onto a periphery of a substrate to realize adhesion enhancement process. Thus, the adhesion between a resist coating film and a substrate surface in the periphery of a substrate is enhanced. Further, parallel implementation of thermal process and adhesion enhancement process exerts no influence on throughput.

  • 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: 20120122038
    Abstract: A method for developing a substrate includes spinning the substrate with a spin holder and discharging a developer to the substrate from a plurality of exhaust ports arranged in a row on a developer feeder. The method also includes causing a moving mechanism to move said developer feeder in one direction extending to a center of the substrate in plan view while maintaining a direction of arrangement of said exhaust ports in said one direction, thereby to move said developer feeder between substantially the center and an edge of the substrate. The method further includes causing the developer discharged from said exhaust ports to impinge in separate streams on the substrate, and causing each of the separate streams to impinge spirally on the substrate, thereby to develop the substrate. At least two of loci of positions of impingement of the developer corresponding to said exhaust ports overlap each other.

  • Patent number: 8166985
    Abstract: When a substrate is subjected to bevel cleaning processing, a first magnet plate is arranged at a lower position, and a second magnet plate is arranged at an upper position. In this case, each of chuck pins enters a closed state in a region outside the first magnet plate, while entering an opened state in a region outside the second magnet plate. That is, a holder in each of the chuck pins is maintained in contact with an outer edge of the substrate when it passes through the region outside the first magnet plate, while being spaced apart from the outer edge of the substrate when it passes through the region outside the second magnet plate.

  • Patent number: 8137576
    Abstract: A method for developing a substrate includes a developing step for supplying a developer to the substrate, and a neutralizing and removing step for supplying a treating solution containing a neutralizing material to the substrate to neutralize the developer, and neutralizing the developer and removing the developer from the substrate. In the neutralizing and removing step, the developer is neutralized by the treating solution. This neutralization reaction forms a product (salt) which easily melts into the treating solution and does not precipitate. Thus, the product is removable from the substrate along with the treating solution. Therefore, the developer is inhibited from remaining on the substrate. As a result, it is possible to prevent post-develop defects due to “residues of the developer” or the developer remaining on the substrate.

  • Patent number: 8122851
    Abstract: A substrate processing apparatus is configured to provide in series a plurality of processing blocks, each block including a processing unit and a transport robot transporting a substrate. A substrate rest is provided in a connecting portion of adjacent processing blocks. A sensor plate with sensor coils is provided spanning over support pins of the substrate rest. Once a temperature-measurement substrate with temperature-measuring elements, each element formed by connecting a coil to a quartz resonator, is placed on the support pins, a transmitter-receiver transmits transmission waves corresponding to the characteristic frequencies of the quartz resonators to the temperature-measuring elements through the sensor coils. After the stop of the transmission, the transmitter-receiver receives electromagnetic waves from the temperature-measuring elements through the sensor coils, and the temperature computer computes the substrate temperature based on the frequencies of the electromagnetic waves.

  • 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.
