Patent ID: 7252099

Claim:
A wafer cleaning apparatus with multiple wash-heads adapted for a wafer cleaning process, comprising: a supporting base including a driving device wherein the driving device comprises a couple of first rotation axes, a couple of second rotation axes, a first transmission belt, a second transmission belt, a third transmission belt, a fourth transmission belt, a first motor driving one of the rotation axes which is conveyed by the third transmission belt, thereby to drive the first transmission belt and further enable the first rotation axis to rotate the rotation module and a second motor driving the fourth transmission belt and further driving one of the second rotation axes thereby to drive the second transmission belt and enable the second rotation axis to rotate the rotation module for controlling the wash-heads to self-rotate and clean wafers; and a rotation module having a top side connected with the driving device, and the rotation module having multiple wash-heads; wherein the bottom side of the wash-head is connected with a wafer, and by using the driving device, the rotation module is wholly driven and the wash-heads self-rotate along a cleaning path for cleaning wafers.
