  • Publication number: 20210317579
    Abstract: A method includes: supporting a rear surface of a substrate with a front surface thereof oriented upward to form a gap between the rear surface and a guide surface facing the rear surface; exhausting the gas outward of the substrate; and forming a thin film on the rear surface through vapor deposition by supplying a raw material gas from a side of the guide surface into the gap via a gas ejection port and heating the gas. The method has at least one of conditions including (a) the forming includes changing, during film formation, a height of the gap from one of a first value and a second value smaller than the first value to the other, and (b) the forming includes changing, during film formation, a ratio of flow rates of the gas ejected from first and second gas ejection ports formed at different radial positions on the substrate.

  • Publication number: 20210232050
    Abstract: A substrate processing apparatus includes a hydrophobizing part configured to perform a hydrophobizing process of forming a hydrophobic film on a front surface of a substrate through vapor deposition of a hydrophobizing gas, an ultraviolet radiation part configured to radiate ultraviolet rays to a removal area on a rear surface of the substrate so as to remove the hydrophobic film formed in the removal area in the hydrophobizing process, and a resin-film forming part configured to form a fluororesin film in the removal area after the hydrophobic film is removed.

  • Patent number: 9418834
    Abstract: This disclosure relates to a processing system for spin-coating a substrate with Molecular Self-assembly (MSA) chemicals to form photoresist films and/or low dielectric constant (low-k) films on the substrate. The spin-coating processing system may include a spin-coating chamber that can receive and spin-coat MSA chemicals onto the substrate and an annealing chamber to thermally treat the substrate after the spin-coat process. In certain embodiments, the spin-coating processing system may also pre-treat or pre-wet the substrate prior to the spin-coating process.

  • Patent number: 4131803
    Abstract: An apparatus for detecting a defect in a sheet like material, comprising: a photodetector provided opposite to a textile sheet in the vicinity of the weaving line of a weaving machine, and a prime mover for slidably driving said photodetector in the lateral direction throughout the width of the weaved textile sheet, characterized in that normally the said prime mover is adapted to convert the moving direction whenever the photodetector reaches either side edge of the weaved textile sheet but is further adapted to reverse the moving direction whenever the photodetector detects a defect in the weaved textile sheet, whereby said photodetector is caused to detect repeatedly the same defect and the weaving machine is controlled to stop the weaving operation whenever the photodetector detects the same defect more times than a predetermined number of times.
