Abstract
An etchant is stored in a treating tank; a glass substrate is transported with transport rollers into the treating tank; the etchant is discharged from below the substrate to raise the substrate to a position above the transport rollers and below the surface of the etchant; the discharge of the etching liquid is stopped and the glass substrate is lowered to a position for contacting the transport rollers; the etchant is drained from the treating tank; and the glass substrate is unloaded with the transport rollers out of the treating tank. The disclosed method and apparatus can treat both front and back surfaces of the substrate uniformly.
