  • Patent number: 10153181
    Abstract: Disclosed is a substrate treating apparatus including the following units: a supplying unit which supplies a process liquid including a sublimable substance in a melt state on a pattern-formed surface of a substrate W; a solidifying unit which solidifies the process liquid on the pattern-formed surface to produce a solidified body; and a sublimating unit which sublimates the solidified body to remove the solidified body from the pattern-formed surface. In this apparatus, the sublimable substance includes a fluorinated carbon compound.

  • Publication number: 20180238621
    Abstract: When a substrate on which a fine pattern is formed is dried with vapor, prevention of collapse of the pattern due to water originally contained in IPA to be stored has been a problem to be solved. A mixed liquid stored in a mixed liquid storage is vaporized to generate mixed vapor containing the IPA and water (water vapor). Then, a vapor dewatering unit connected to a vapor supply pipe through which the mixed vapor is fed removes water in the mixed vapor. This can reduce the concentration of water originally contained in the IPA to be stored before the IPA is supplied to the substrate, thereby suppressing collapse of the pattern.

  • Patent number: 9859110
    Abstract: An ultrasonic wave applying liquid is supplied to one principal surface of a substrate while a liquid film of a first liquid being formed on another principal surface of the substrate. The ultrasonic wave applying liquid is obtained by applying ultrasonic waves to a second liquid. Ultrasonic vibration is transmitted to the other principal surface and the liquid film, thereby ultrasonically cleaning the other principal surface. The first liquid has a higher cavitation intensity, which is a stress per unit area acting on the substrate by cavitation caused in the liquid when ultrasonic waves are transmitted to the liquid present on the principal surface of the substrate, than the second liquid.

  • Publication number: 20170043379
    Abstract: After hydrophobization of surfaces of patterns, a liquid film of pure water or the like is formed on the surfaces of the substrate. At this stage, the liquid of the liquid film cannot be present between the patterns because of hydrophobization, and gas is present there. With the front surface of the substrate covered with the liquid film, a liquid to which ultrasonic waves are applied is supplied to the back surface of the substrate, whereby the back surface of the substrate is cleaned due to the cavitation collapse energy in the liquid caused by the ultrasonic waves. While collapse of cavitation occurs at the front surface of the substrate, the presence of the gas between the patterns prohibits collapse of cavitation between the patterns, the liquid film can prevent contamination while preventing collapse of the patterns, and the back surface of the substrate is cleaned favorably.
