Claim:
1. A particle cleaning module, comprising: a housing; a substrate holder disposed in the housing, the substrate holder configured to retain a substrate in a substantially vertical orientation, the substrate holder rotatable on a first axis; a first pad holder disposed in the housing, the first pad holder having a pad retaining surface facing the substrate holder in a parallel and spaced apart relation, the first pad holder rotatable on a second axis disposed parallel to the first axis; a first actuator operable to move the first pad holder relative to the substrate holder to change a distance defined between the first pad holder and the substrate holder; a first lateral actuator operable to move the first pad holder linearly across a major surface of the substrate holder through the first axis; a second pad holder disposed in the housing, the second pad holder having a pad retaining surface facing the substrate holder in a parallel and spaced apart relation, the second pad holder rotatable on a third axis parallel to the first axis and the second axis; and a second lateral actuator operable to move the second pad holder linearly across the major surface of the substrate holder in parallel with movement of the first pad holder and without intersecting the first axis.
