  • Patent number: 10835932
    Abstract: It is an object to prevent adhesion of a processing liquid to a non-processing region of a substrate. In order to achieve the object, a substrate processing apparatus includes a substrate rotating mechanism, a discharging portion for discharging a processing liquid to a substrate, a moving portion for moving a discharging portion, and a controller. The discharging portion starts to discharge the processing liquid at a first position and is moved to a second position. The first position is a position of the discharging portion where a section of a passage of the discharging portion is projected onto a first region, and the second position is a position of the discharging portion where the section of the passage is projected onto a second region. The first region is a region on the peripheral edge side of the substrate from the second region.

  • Patent number: 10840083
    Abstract: Provided is a substrate cleaning method for cleaning a substrate having an oxide film on the surface thereof. The method includes a partial etching step of etching the oxide film to a predetermined film thickness, and a physical cleaning step of executing physical cleaning on the surface of the substrate after the partial etching step. The oxide film may be a natural oxide film with particles at least partially taken into the film. In this case, the partial etching step may either expose the particles from the natural oxide film or increase the exposed portion from the natural oxide film. The physical cleaning may remove, by physical action, the particles exposed from the natural oxide film while leaving the natural oxide film on the surface of the substrate.

  • Patent number: 10840096
    Abstract: A substrate on which a processing film made of a directed self-assembly material is formed is placed on a holding plate incorporating a preheating mechanism, and is preheated. A low oxygen atmosphere surrounds the substrate. A preheating temperature is a temperature at which the directed self-assembly material comprised of two types of polymers is phase-separated. By preheating the processing film, the two types of polymers are phase-separated to form a fine pattern. The processing film is irradiated with flashes of light from flash lamps while being preheated. This increases the fluidity of the polymers constituting the processing film to achieve the formation of a fine pattern while suppressing the occurrence of defects.

  • Patent number: 10832925
    Abstract: A heating plate is stored in a chamber. With a solvent containing gas present in the chamber, a substrate on which a DSA film is formed is held at a position further upward than the heating plate. Thus, neutralization of an atmosphere is performed at a temperature at which microphase separation does not occur. Thereafter, with the solvent containing gas present in the chamber, the substrate is held on an upper surface of the heating plate. Thus, thermal processing is performed on the DSA film on the substrate.

  • Patent number: 10814251
    Abstract: Processing liquid is stored by a supply tank. The dissolved oxygen concentration of the processing liquid is measured. The dissolved oxygen concentration of the processing liquid in the supply tank is adjusted by supplying concentration adjusting gas having a concentration of inert gas higher than that of air into the supply tank in accordance with the dissolved oxygen concentration of the processing liquid measured. The processing liquid in the supply tank is supplied to a substrate. The processing liquid that has been supplied to the substrate is collected to the supply tank. Unnecessary gas that is a gas other than the concentration adjusting gas and dissolved in the processing liquid during the processing of the substrate is decreased from the processing liquid before the processing liquid is collected to the supply tank.

  • Patent number: 10807128
    Abstract: When a chamber of a heat treatment apparatus is opened for a purpose such as maintenance of the heat treatment apparatus, particles flow in large quantities into the chamber together with an outside atmosphere. After maintenance work is finished, an enclosed space is formed in the chamber and gas in the chamber is exhausted to place the interior of the chamber in a reduced-pressure atmosphere. While the interior of the chamber is in the reduced-pressure atmosphere, the interior of the chamber is irradiated with a flash of light emitted multiple times from a flash lamp to cause momentary gas expansion and subsequent gas shrinkage repeatedly, thereby causing particles adhering in the chamber to fly. The flying particles are discharged from the chamber to remove the particles.
