Claim 0:
1. A cleaning machine, comprising:
a wet cleaning module, configured to execute a wet cleaning process on a wafer;
a dry cleaning module, configured to execute a dry cleaning process on the wafer;
a conveying module, configured to input the wafer into the wet cleaning module or the dry cleaning module, or output the wafer from the wet cleaning module or the dry cleaning module;
a transferring module, configured to transfer the wafer from the wet cleaning module to the dry cleaning module, or transfer the wafer from the dry cleaning module to the wet cleaning module;
a processing module, configured to extract gas from the transferring module; and
a first channel by means of which the transferring module is connected to the dry cleaning module, and a second channel by means of which the transferring module is connected to the wet cleaning module;
wherein the transferring module comprises:
a bearing unit, configured to bear the wafer conveyed from the wet cleaning module to the dry cleaning module or configured to bear the wafer conveyed from the dry cleaning module to the wet cleaning module;
a first blocking unit, configured to open or close the first channel, and open the first channel when the wafer needs to be transferred between the bearing unit and the dry cleaning module;
a second blocking unit, configured to open or close the second channel, and open the second channel when the wafer needs to be transferred between the bearing unit and the wet cleaning module; and
a control unit, configured to open or close the first blocking unit and the second blocking unit.
