  • Patent number: 9581907
    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: 8580340
    Abstract: After a solvent is discharged onto a substrate in a period from a time point t0 to a time point t1, rotation of the substrate is started at a time point t2. A resist liquid is discharged onto a center portion of a target surface of the substrate at a time point t3. A rotation speed of the substrate starts to decrease at a time point t4, and attains a first speed after a certain period of time. The discharge of the resist liquid is stopped at a time point t5. The rotation of the substrate is accelerated in a period from a time point t6 to a time point t7, and the rotation speed of the substrate attains a second speed at the time point t7. The rotation of the substrate is decelerated in a period from the time point t7 to a time point t8, and the rotation speed of the substrate attains a third speed at the time point t8.

    Abstract: A substrate processing apparatus comprises an indexer block, an anti-reflection film processing block, a resist film processing block, a development processing block, and an interface block. An exposure device is arranged adjacent to an interface block. The interface block comprises a drying processing group including two drying processing units and an interface transport mechanism. After a substrate is subjected to exposure processing by the exposure device, the substrate is transported to the drying processing units in the drying processing group by the interface transport mechanism, where the substrate is subjected to cleaning and drying processings.

  • 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: 7017658
    Abstract: A heating unit having a heat pipe structure includes a heater and a cooling pipe disposed in an inner space of a holding table. The holding table and the cooling pipe are thermally insulated by a heat-insulating member, so that it is possible to prevent direct heat transfer from the cooling pipe to the holding table. Therefore, it is possible to rapidly perform a cooling processing while keeping the evenness of the temperature distribution of the mounting face and the temperature distribution of the substrate mounted on the mounting face, and consequently to appropriately keep the evenness of the film thickness and the line width of a wiring layer formed on the substrate upon heat processing.

  • Publication number: 20050220985
    Abstract: A substrate processing apparatus is provided with a film quality measuring device that measures the density of a resist film on a substrate as the film quality. Measurement of the density of the resist film is performed after resist-coating or during or after heat-treatment followed by the resist-coating. The film quality measuring device also measures the thickness of the resist film on the substrate before exposure after the heat-treatment followed by the resist-coating. A controller controls a processing condition in a coater or a heating device so that each of the density and thickness of the resist film on the substrate falls within an acceptable range.
