Claim 3:
4. The method for simulating electricity of a wafer chip of claim 3, wherein verifying the correspondence between the actual electrical data and the spectroscopic data comprises:
providing a test wafer chip;
performing the target key process on the test wafer chip to obtain spectroscopic data of the semiconductor structure of the test wafer chip obtained from the target key process, the spectroscopic data being test spectroscopic data;
simulating electrical data of the test wafer chip based on the test spectroscopic data and the database, the electrical data being test electrical data;
obtaining actual electrical data of the test wafer chip of the test wafer chip after all processes;
comparing the test electrical data with the actual electrical data of the test wafer chip to obtain a value of correlation between the test electrical data and the actual electrical data; and
determining whether or not the correspondence between the test spectroscopic data and the test electrical data is credible according to the value of correlation.
