Patent ID: 7155767

Claim:
A scrub cleaning device comprising: a pair of planar scrubbers having their scrub surfaces disposed opposite to each other and holding a substrate rotatably therebetween; means for rotating the pair of planar scrubbers around a rotation shaft vertical to the planar scrubbers for conveying the substrate held between the pair of planar scrubbers; a substrate inlet section for introducing the substrate between the pair of planar scrubbers; a first cleaning point for temporarily holding the substrate being conveyed by the pair of planar scrubbers and for rotating the substrate at a holding position with a rotation axis of the substrate fixed, to perform a first scrub cleaning of the substrate; a guide member disposed along a conveyance direction of the substrate for abutting a part of a circumference of the substrate being conveyed by the pair of planar scrubbers to guide the conveyance of the substrate to the first cleaning point; and a second cleaning point including means for rotating the substrate with the rotation axis of the substrate not fixed, by a friction force generated by the abutment of the guide member with the substrate causing the substrate and the planar scrubbers to rub each other, to perform a second scrub cleaning of the substrate while the substrate is conveyed by the rotation of the planar scrubbers.
