  • 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: 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: 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.

  • Publication number: 20080226830
    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.

  • Publication number: 20080053487
    Abstract: A method capable of eliminating occurrence of a development failure when a DI water discharge nozzle 20 is scanned to dry a substrate by spinning is provided. A substrate W is held in a horizontal posture by a spin chuck 10 and rotated about a vertical axis by a rotation motor 14, and when an outlet of the nozzle 20 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 20 has started to move, only one dried core is produced in the vicinity of the center of the substrate W, and thus production of not less than two dried cores in the vicinity of the center of the substrate W is prevented. The dried region is spread all over the surface of the substrate W.

  • Publication number: 20070274711
    Abstract: A cleaning substrate for use in the cleaning operation for a substrate stage in an exposure unit compatible with immersion exposure and a dummy substrate for use during the adjustment of an exposure position of a pattern image in the exposure unit are held in a cleaning substrate housing part and a dummy substrate housing part, respectively, which are provided in a substrate processing apparatus. For the cleaning operation for the substrate stage or an alignment operation in the exposure unit, the cleaning substrate or the dummy substrate is transferred from the substrate processing apparatus to the exposure unit. A back surface cleaning process on the cleaning substrate or the dummy substrate is performed in a back surface cleaning unit of the substrate processing apparatus immediately before or immediately after the cleaning operation for the substrate stage or the alignment operation.

  • Publication number: 20070253710
    Abstract: In an exposure unit compatible with immersion exposure, a dummy substrate to be used for an alignment process for adjustment of an exposure position for a pattern image is transferred to a substrate processing apparatus for performing a resist coating process before exposure and a development process after exposure. In the substrate processing apparatus, the received dummy substrate is reversed and transferred to a back surface cleaning unit, to be subjected to a back surface cleaning process. After that, the dummy substrate is reversed again and transferred to a front surface cleaning unit, to be subjected to a front surface cleaning process. The dummy substrate after being cleaned is transferred back from the substrate processing apparatus to the exposure unit. Since the alignment process can be performed by using a clean dummy substrate in the exposure unit, it is possible to reduce contamination of mechanisms in the exposure unit, such as a substrate stage and the like.

  • Publication number: 20070147832
    Abstract: Immediately before or immediately after an alignment process for adjusting an exposure position of a pattern image in an exposure unit compatible with immersion exposure, a dummy substrate for use in the alignment process is transported from the exposure unit to a substrate processing apparatus. In the substrate processing apparatus, a cleaning processing unit cleans and dries the received dummy substrate. The cleaned dummy substrate is transported from the substrate processing apparatus back to the exposure unit. The use of the clean dummy substrate for the execution of the alignment process in the exposure unit reduces contamination of mechanisms within the exposure unit, such as a substrate stage. When the dummy substrate is water-repellent, the cleaning in the substrate processing apparatus restores the water repellency of the dummy substrate.

  • Publication number: 20070147831
    Abstract: A substrate processing apparatus for performing an exposure process by printing a pattern on a substrate coated with a photosensitive material includes an exposure part for performing an immersion exposure process, a cleaning part and a transport mechanism which are provided within an exposure chamber. After the exposure part performs the immersion exposure process on the substrate, the substrate is transported to the cleaning part and is cleaned therein. If the liquid used during the immersion exposure process remains on the substrate after the exposure process, the substrate is cleaned in the cleaning part immediately after the exposure process. This prevents the remaining liquid from adhering to and contaminating mechanisms within the substrate processing apparatus. Also, the cleaning part is able to clean a dummy substrate for use in an alignment process in the exposure part.
