  • Publication number: 20170084470
    Abstract: A drying time after cleaning a surface of a cleaning target including a wall which constitutes a processing chamber of a substrate processing apparatus and a device provided within the processing chamber can be shortened. After performing a cleaning process of dissolving a removal target adhering to the surface of the cleaning target with water by discharging the water into the processing chamber 20 and allowing the surface of the cleaning target 42, 20a and 53 to be wet with the water, a solvent supplying process of supplying a solvent having higher volatility than the water toward the water adhering to the surface of the cleaning target is performed by discharging the solvent into the processing chamber. Then, a drying process of drying the surface of the cleaning target is performed.

  • Patent number: 7182531
    Abstract: In this developing method and apparatus, a concentration measuring unit 222 picks part of developing fluid in a blending tank 186 to measure the resist concentration by an absorption photometry and feeds the detected resist concentration to a control unit 240. The control unit 240 controls respective valves 210, 212, 216 of a TMAH concentrate solution 200, a solvent pipe 204 and a drain pipe 208 in a manner that the developing fluid in the blending tank 186 has a TMAH concentration corresponding to a measured resist-concentration value to accomplish a constant developing rate, performing component control of the developing fluid. The developing fluid transferred from the blending tank 186 to a supply tank 188 is fed to a developer nozzle DN in a developing section 126 through a developer pipe 224 owing to the drive of a pump 228. Accordingly, even if the developing fluid is reused in the developing process in multiple times, it is possible to make sure of the uniformity in development.

  • Patent number: 6749688
    Abstract: A coating apparatus has a spin chuck for attracting and holding a semiconductor wafer in a horizontal state by means of vacuum. A movable beam is arranged above the spin chuck. The movable beam includes first and second nozzles integrally formed. The first nozzle is used for supplying a photo-resist liquid while the second nozzle is used for supplying a solvent for the photo-resist liquid. When a coating process is performed, the movable beam above the wafer is horizontally moved in one direction. The solvent is first supplied onto the wafer from the second nozzle, and the coating or photo-resist liquid is then supplied from the first nozzle, following the solvent. Wettability of the wafer relative to the photo-resist is increased by the solvent, prior to supply of the photo-resist liquid.

  • Publication number: 20020187423
    Abstract: A substrate coated with a coating solution, for example, a resist solution is heated at a predetermined temperature, thereafter putted in a non-heated state, and then heated at a second predetermined temperature. Alternatively, a heating process in which a substrate coated with a resist solution is heated and a non-heated process in which the substrate is putted in a non-heated state are repeated a plurality of times. The adoption of the above treating methods can prevent the occurrence of transfer which is an index of ununiformity of film thickness of a resist solution and the like and change in line width of a circuit pattern, thus improving yield in substrate treatment.

  • Patent number: 6443641
    Abstract: Just after resist solution is coated on a substrate, it is dried substantially in a non-heating state. In reality, inertia gas or the like is blown from a shower head to the substrate. Thus, the resist solution coated on the substrate is dried. Consequently, transfer marks that cause the film thickness of resist film to be unequal and the line width of a circuit pattern to fluctuate can be prevented.
