  • Publication number: 20090073394
    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: 20090071940
    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.

  • Publication number: 20090074402
    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: 7500781
    Abstract: The temperature of a wafer is measured using thermal sensors that are embedded in elastomeric diaphragms positioned in holes formed in a support layer of a bake plate. A pressure differential caused by heating the bake plate causes the elastomeric diaphragms to contact the wafer. The thermal sensors determine the temperature of the wafer at the locations where the elastomeric diaphragms contact the wafer.

  • Publication number: 20090060686
    Abstract: A chilled arm that transports a substrate to and from a heating plate for performing a heating process on the substrate is formed with a flow passage pipe therein, and cools the entire holding area thereof opposed to the substrate held by the chilled arm to a predetermined reference temperature by supplying circulating cooling water through the flow passage pipe. Six polyimide heaters are affixed to the holding area to control the temperature of at least a portion of the holding area at a temperature different from the reference temperature. These two temperature control mechanisms intentionally provide a temperature distribution to the holding area to thereby provide an intentional temperature distribution to the substrate before and after the heat treatment by the heating plate. This reduces the nonuniformity of a temperature distribution which typically occurs in the heating plate to accomplish a uniform heat treatment throughout the heat treatment process step.

  • Publication number: 20090014126
    Abstract: A substrate processing apparatus includes a development part for performing a development process on a substrate after being subjected to exposure and a cleaning part. When the processing time in the development part is shorter than the reference time determined in advance, the development part performs all the process steps for development. On the other hand, when the processing time in the development part is longer than the reference time, the development process is split into a first half process step and a second half process step, and the development part performs a processing including the first half process step and the cleaning part performs a processing including the second half process step. Even if the development process takes a long time, it is possible to prevent deterioration in processing capability of the substrate processing apparatus on the whole by splitting the development process.
