Abstract: A static electricity visualization apparatus capable of visually identifying a measured level of static electricity is provided. The static electricity visualization apparatus comprises a photographing unit for generating a first photographed image obtained by photographing a measurement target at a first distance from the measurement target in a first mode, and generating a second photographed image obtained by photographing the measurement target at a second distance from the measurement target in a second mode, a static electricity sensor for measuring a static electricity level of the measurement target at the second distance from the measurement target, a processor for matching the second photographed image with the first photographed image, and an output unit for outputting a static electricity visualization image that visualizes a static electricity level measured by the static electricity sensor on the first photographed image, wherein the static electricity visualization image comprises a color corresponding to the static electricity level of the measurement target measured by the static electricity sensor at a position where the second photographed image matches on the first photographed image.

Abstract: The present invention provides a method for treating a substrate. The method for treating a substrate comprises: a monitoring step of calculating a flow rate of a liquid, comparing the calculated measurement flow rate of the liquid with a set flow rate of the liquid in a normal state, and determining whether an error occurs in the measurement flow rate; and when an error is determined to occur in the measurement flow rate in the monitoring step, a feedback step of performing feedback control of a discharge flow rate of the liquid discharged to the substrate, wherein the feedback step determines a type of the error, and differently performs the feedback control according to the determined type of the error.
