Abstract: PURPOSE: A method for loading a wafer toward a cassette in semiconductor equipment is provided to prevent a damage of a wafer and generation of particles by inspecting a change of the cassette on a loading portion in a wafer transferring process and a wafer loading process. CONSTITUTION: The first wafer mapping process is performed to load a cassette including wafers on a loading portion and checking the number of wafers loaded into the cassette and slots of the cassette(S10). The wafer is selectively transferred from the cassette to a wafer chuck and a processed state of the selected wafer is inspected(S12,S14). A shifting state of the cassette loaded on the loading portion is checked during an inspection process of the processed wafer and an error is generated when the cassette is shifted(S16,S18). The second mapping process is performed only if the error is generated(S20). The wafer is loaded into the slot of the cassette if the cassette is not changed or the error is not generated.
