A semiconductor wafer analysis system is provided. In an embodiment, the semiconductor wafer analysis system includes a tester to test semiconductor wafers manufactured by at least one manufacturing facility, a wafer map generation module to generate wafer maps on the basis of the test results from the tester, and a wafer analysis module. The wafer analysis module may include a data generation module that divides each wafer map into a plurality of defect analysis regions and generates feature vectors representing the semiconductor wafers, and an operation module that statistically analyzes the feature vectors.
