  • Publication number: 20190027383
    Abstract: Pure water, a mixed solution, and an organic solvent are applied to a substrate in this order. The organic solvent is then removed by rotation. The mixed solution is a mixture of pure water and the organic solvent, and has a surface tension lower than that of the pure water. Since the mixed solution has a solubility in pure water, which is higher than that of the organic solvent, local drying on the upper surface becomes less likely at an interface between the mixed solution and the pure water, which suppresses collapse of pattern elements. Since the temperature of the substrate is raised by the mixed solution having a temperature higher than room temperature, it is possible to reduce the time required for a process related to drying.

  • Publication number: 20180301357
    Abstract: A substrate processing apparatus includes a chamber, a substrate holding part, a substrate rotating mechanism, and a processing liquid supply part. The chamber includes a chamber body and a chamber cover, and the chamber cover is moved up and down by a chamber opening and closing mechanism. A top plate is attached to the chamber cover. While the chamber cover is in contact with the chamber body, a sealed space is formed and processing is performed. When the chamber cover is moved up, an annular opening is formed between the chamber cover and the chamber body. A cup part is positioned outside the annular opening. A processing liquid spattering from a substrate is received by the cup part.

  • Patent number: 10103020
    Abstract: A substrate processing apparatus includes a substrate holding part, a substrate rotating mechanism, a processing liquid supply part for supplying a processing liquid onto the substrate, a cup part for receiving the processing liquid spattering from the substrate being rotated, by its inner peripheral surface, a top plate disposed above the substrate, and a liquid film forming part for forming a rotating liquid film which rotates in the same direction as the substrate does, on the inner peripheral surface of the cup part, by supplying a liquid onto an upper surface of the top plate rotating in the same direction as the substrate rotates, in parallel with a processing of the substrate with the processing liquid. It is possible to prevent droplets caused by collision of the processing liquid spattering from the substrate against the cup part from being deposited on the substrate.

  • Patent number: 9997380
    Abstract: In a substrate processing apparatus, a chamber bottom has a plurality of large chamber exhaust ports arranged in a circumferential direction. A cup rotation mechanism rotates a cup part so that a cup exhaust port selectively overlaps with one of the large chamber exhaust ports. With the cup exhaust port overlapping with one large chamber exhaust port, the gas in the cup part is discharged to the outside of the chamber via a first exhaust mechanism. With the cup exhaust port overlapping with another large chamber exhaust port, the gas in cup part is discharged to the outside of the chamber via a second exhaust mechanism. By rotating the cup part in the chamber via the cup rotation mechanism, the substrate processing apparatus can easily switch the exhaust mechanism for exhausting gas from the cup part.

  • Publication number: 20180012778
    Abstract: In a substrate processing apparatus, a cup part is moved in an up-down direction to cause a cup exhaust port to selectively overlap a first chamber exhaust port or a second chamber exhaust port. In the state in which the cup exhaust port overlaps the first chamber exhaust port, gas in the cup part is discharged through the cup exhaust port and the first chamber exhaust port by a first exhaust mechanism. In the state in which the cup exhaust port overlaps the second chamber exhaust port, the gas in the cup part is discharged through the cup exhaust port and the second chamber exhaust port by a second exhaust mechanism. In this way, an exhaust mechanism for exhausting gas from the cup part can be easily switched between the first exhaust mechanism and the second exhaust mechanism.

  • Patent number: 9452361
    Abstract: A network game system includes a game server in which a plurality of players respectively operating a plurality of portable communication terminals are registered in advance. When any one of the players logs in the game server through a communication network, a game is supplied to the portable communication terminal of the player. A game screen is shown on a display, and both characters in the course of logging-in and logging out are displayed on the game screen. If the player selects the logging-out character, a selection signal is transmitted to the game server. The game server transmits a log-in operation request to the portable communication terminal of the player operating the selected character.
