Patent ID: 8025737

Claim:
A substrate cleaning apparatus for cleaning a first clean target surface positioned on a front side of an edge portion of a substrate and a second clean target surface positioned on a back side of the edge portion of the substrate by a fabric cleaning tape including a first wiping surface and a second wiping surface, the substrate cleaning apparatus comprising: a first presser member for pressing the cleaning tape against the first clean target surface; a second presser member for pressing the cleaning tape against the second clean target surface; a tape path forming member which forms a tape path for the cleaning tape, the tape path passing through between the first presser member and the first clean target surface and between the second presser member and the second clean target surface; a tape feeding device which feeds the cleaning tape to the tape path; a tape collecting device which collects the cleaning tape from the tape path; a tape driving device which drives the cleaning tape; a cleaner discharging device which discharges a cleaner to the cleaning tape; and a moving device for moving the cleaning tape and the substrate relative to each other in a longitudinal direction of the edge portion of the substrate, wherein the tape path includes: a first path which allows the cleaning tape to pass through between the first presser member and the first clean target surface in a direction orthogonal to the longitudinal direction of the edge portion of the substrate with the first wiping surface facing the first clean target surface; a second path which allows the cleaning tape, which has passed through the first path, to be looped so that the second wiping surface faces the back side of the substrate; and a third path which allows the cleaning tape, which has passed through the second path, to pass through between the second presser member and the second clean target surface in a direction identical to the passage direction of the cleaning tape in the first path with the second wiping surface facing the second clean target surface.
