  • Patent number: 10643835
    Abstract: Provided is a substrate processing apparatus that removes a film by supplying a processing liquid to the peripheral edge of a substrate. An ejection unit ejects the processing liquid to the peripheral edge of the substrate held and rotated by a substrate holding unit. An ejection position setting unit sets the ejection position of the processing liquid of the ejection unit to correspond to the removal width of the film included in a recipe, and a property information acquisition unit acquires property information of the film to be removed. A correction amount acquisition unit acquires the correction amount for correcting the ejection position of the processing liquid based on the property information of the film, and an ejection position correction unit corrects the ejection position of the processing liquid by the ejection unit based on the correction amount acquired by the correction amount acquisition unit.

  • Patent number: 10500750
    Abstract: A cutting apparatus includes a crop mark print controller and a front/back determiner. The crop mark print controller prints a first crop mark on a front side of a medium and then print a second crop mark over the first crop mark. The second crop mark is larger in size than the first crop mark. The front/back determiner determines that the medium is placed, with its front side facing upward, when only the second crop mark is detected by a crop mark detector, and determine that the medium is placed, with its back side facing upward, when a pattern including the first crop mark and the second crop mark overlapping one another is detected by the crop mark detector.
