Claim 9:
10. A cleaning method applied to the cleaning machine of claim 1, comprising:
acquiring a wafer to be cleaned and a cleaning process of the wafer;
determining, on a basis of the cleaning process of the wafer, whether the wafer to be cleaned needs to be subjected to the dry cleaning process and the wet cleaning process and a cleaning sequence of the dry cleaning process and the wet cleaning process; and
controlling, on a basis of the cleaning sequence, a position of the wafer on the cleaning machine, so as to complete cleaning of the wafer;
when the cleaning sequence is to execute the wet cleaning process first and then the dry cleaning process, the controlling, on a basis of the cleaning sequence, a position of the wafer on the cleaning machine, so as to complete cleaning of the wafer comprises:
inputting the wafer into the wet cleaning module by using the conveying module, and executing the wet cleaning process on the wafer by using the wet cleaning module;
extracting the gas from the transferring module by using the processing module;
transferring the wafer from the wet cleaning module to the dry cleaning module by using the transferring module;
executing the dry cleaning process on the wafer by using the dry cleaning module; and
outputting the wafer from the dry cleaning module by using the conveying module; and

when the cleaning sequence is to execute the dry cleaning process first and then the wet cleaning process, the controlling, on a basis of the cleaning sequence, a position of the wafer on the cleaning machine, so as to complete cleaning of the wafer comprises:
inputting the wafer into the dry cleaning module by using the conveying module, and executing the dry cleaning process on the wafer by using the dry cleaning module;
extracting the gas from the transferring module by using the processing module;
transferring the wafer from the dry cleaning module to the wet cleaning module by using the transferring module;
executing the wet cleaning process on the wafer by using the wet cleaning module; and
outputting the wafer from the wet cleaning module by using the conveying module.
