Substrate cleaning method, substrate cleaning system and program storage medium
Abstract:
A substrate cleaning method can uniformly removing particles from substrates at a high removing efficiency. The substrate cleaning method includes the steps of immersing substrates W in a cleaning liquid in a cleaning tank 12, and generating ultrasonic waves in the cleaning liquid contained in the cleaning tank. A region in the cleaning tank toward which the cleaning liquid is supplied is varied with respect to a vertical level in the step of generating ultrasonic waves in the cleaning liquid while the cleaning liquid is being supplied into the cleaning tank.
