  • Patent number: 11084072
    Abstract: Contamination of a bottom surface of a substrate caused by a processing liquid used for cleaning a top surface of the substrate can be suppressed. After performing a liquid processing on the top surface of the substrate and a liquid processing on the bottom surface of the substrate in parallel while rotating the substrate by a substrate holding/rotating unit, when stopping the liquid processing on the top surface of the substrate and the liquid processing on the bottom surface of the substrate, a control unit 18 stops a supply of the processing liquid onto the top surface of the substrate by a first processing liquid supply device 73, and then, stops a supply of the processing liquid onto the bottom surface of the substrate by a second processing liquid supply device 71.

Further, the substrate polishing unit polishes the substrate with a polishing area determined on the basis of information acquired from a prior process. Furthermore, the polishing is performed by using any one or all of a plurality of substrate polishing units determined on the basis of information acquired from a prior process.

  • Patent number: 8794250
    Abstract: A substrate processing apparatus according to the present invention is provided with a spin chuck (3) that holds a substrate (W) and rotates the same. A process liquid supply system (11, . . . ) is disposed to supply a process liquid to the substrate rotated by the spin chuck. There are disposed a fluid nozzle (12) that supplies to the substrate a drying fluid having a higher volatility than that of the process liquid, and an inert gas nozzle (13) that supplies an inert gas to the substrate. A nozzle moving mechanism (15, 52, . . . ) is disposed that moves the nozzles (12, 13) radially outward relative to a rotational center (Po) of the substrate, while maintaining the inert gas nozzle nearer to the rotational center of the substrate than the fluid nozzle.

  • Patent number: 8137478
    Abstract: A substrate (W) is processed with the use of a process liquid such as a deionized water. Then, a first fluid which is more volatile than the process liquid is supplied to an upper surface of the substrate (W) from a fluid nozzle (12) to form a liquid film. Next, a second fluid which is more volatile than the process liquid is supplied to the upper surface of the substrate (W) from the fluid nozzle (12), while the wafer (W) is being rotated. During this supply operation, a supply position (Sf) of the second fluid to the substrate (W) is moved radially outward from a rotational center (Po) of the substrate (W). As a result, it is possible to prevent the generation of particles on the substrate (W) after it is dried by using the first and second fluids.

  • Patent number: 7914626
    Abstract: A liquid processing method includes: placing a plate adjacently to at least one of surfaces of a target substrate, and supplying a process liquid into a gap between the plate and the target substrate, thereby forming a liquid film of the process liquid; subjecting the target substrate to a process using a state with the liquid film of the process liquid thus formed; and supplying a gas to the liquid film, thereby breaking the liquid film, after finishing the process.

  • Patent number: 7731799
    Abstract: A substrate processing method which removes an ArF resist film from a wafer having the ArF resist film. As an ultraviolet irradiation process is performed on the ArF resist film, and then an ozone gas and water vapor are fed to the ArF resist film, the ArF resist film is altered in a water-soluble state. Thereafter, the ArF resist film is removed from the substrate by feeding pure water to the ArF resist film altered into the water-soluble state.

  • Patent number: 7693597
    Abstract: A substrate processing method for removing a resist film from a substrate having the resist film formed thereon comprises maintaining the inner region of the chamber at a prescribed temperature by putting a substrate in a chamber, denaturing the resist film by supplying ozone and a water vapor in such a manner that ozone is supplied into the chamber while a water vapor is supplied into the chamber at a prescribed flow rate, the amount of ozone relative to the amount of the water vapor being adjusted such that the dew formation within the chamber is prevented, and processing the substrate with a prescribed liquid material so as to remove the denatured resist film from the substrate.
