摘要：
The present invention provides a substrate cleaning method capable of removing particles from the entire surface of a substrate to be processed at a high removing efficiency. In the substrate cleaning method according to the present invention, a substrate to be processed W is immersed in a cleaning liquid in a cleaning tank 12. Then, ultrasonic waves are generated in the cleaning liquid contained in the cleaning tank 12, so that the substrate to be processed W is subjected to an ultrasonic cleaning process. While the substrate to be processed is being cleaned, a dissolved gas concentration of a gas dissolved in the cleaning liquid contained in the cleaning tank is changed.
