Patent number: 10629459Abstract: A substrate processing apparatus has a cup part for receiving processing liquid such as pure water which is splashed from a substrate. The cup part is formed of electrical insulation material. Hydrophilic treatment may be performed on an outer annular surface of the cup part. Water is held on at least one surface of the cup part while processing the substrate. The water may be substantially grounded. With the disclosed apparatus, charged potential of the cup part generated by splashing of pure water can be suppressed, without greatly increasing the manufacturing cost of the substrate processing apparatus. As a result, it is possible to prevent electric discharge from occurring on the substrate due to induction charging of the substrate, in application of the processing liquid onto the substrate.Type: GrantFiled: November 30, 2017Date of Patent: April 21, 2020Assignee: SCREEN Holdings Co., Ltd.Inventors: Masahiro Miyagi, Masanobu Sato, Hiroyuki Araki
