  • Publication number: 20240238848
    Abstract: A substrate processing apparatus includes a support unit, a supply unit, an annular member, a rotation unit, a cover member, and an annular flow regulation member disposed above the cover member. The annular member includes an inclined surface inclined downward toward a center of the annular member in a radial direction. The flow regulation member includes a base portion and a protrusion which faces a circumferential portion of the substrate supported on the support unit and protrudes from the base portion toward the circumferential portion of the substrate. The protrusion overlaps the support unit when viewed in a vertical direction. A lower surface of the protrusion is positioned above an upper surface of the substrate supported on the support unit and positioned below an upper surface of the annular member. An inner circumferential surface of the protrusion is inclined radially outward from an upper side to a lower side.

  • Publication number: 20240142360
    Abstract: A dispersion stability evaluation method is a method for evaluating a dispersion stability of dispersoid dispersed in a dispersion medium. The dispersion stability evaluation method includes a first step of holding a sample including the dispersion medium and the dispersoid on a reflective surface, and a second step of causing terahertz waves to be incident on the reflective surface from a side opposite to the sample and detecting the terahertz waves reflected by the reflective surface. In the second step, while a state where the dispersoid are allowed to move toward the reflective surface is maintained, a plurality of detection results respectively corresponding to a plurality of times apart from each other are acquired.
