Patent number: 11919051Abstract: A processing solution containing solvent and solute is supplied onto a substrate (9). The processing solution transforms into a particle retention layer as a result of at least part of the solvent being volatilized from the processing solution and causing the processing solution to solidify or harden. The particle retention layer is removed from the substrate (9) by supplying a removal liquid onto the substrate (9). A solute component contained in the particle retention layer is insoluble or poorly soluble in the removal liquid, whereas the solvent is soluble. The solute component contained in the particle retention layer has the property of being altered to become soluble in the removal liquid when heated to a temperature higher than or equal to an alteration temperature. The removal liquid is supplied after the formation of the particle retention layer, without undergoing a process of alternating the solute component.Type: GrantFiled: July 7, 2022Date of Patent: March 5, 2024Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Yukifumi Yoshida, Ayumi Higuchi, Naoko Yamaguchi
