    Abstract: In a semiconductor wafer manufacturing apparatus, a rotation module is provided to hold the semiconductor wafer at a plane. The semiconductor wafer is revolved by the rotation module around a first axis. The first axis is substantially perpendicular to the plane. A cleaning module is configured to revolve around a second axis when the cleaning module contacts the surface of the semiconductor wafer. A mechanism is further provided to enable the rotation module and/or the cleaning module to move along a direction substantially perpendicular to the first axis. Consequently, the relative velocities at the contact points between the semiconductor wafer and the cleaning module are changed. Moreover, no relative velocity at any contact point between the semiconductor wafer and the cleaning module is zero or close to zero.
