  • Patent number: 11837477
    Abstract: A substrate washing device includes a roll washing member, a single tube nozzle and spray nozzle. The roll washing member linearly extends over the entire length of the diameter of the substrate and comes into slide-contact with the surface of the substrate. The single tube nozzle discharges washing liquid onto a roll winding side of the roll washing member so that the first washing liquid lands in the front center of the substrate. The spray nozzle sprays a second washing liquid in a fan shape toward a second area when the roll winding side area is divided into two areas.
