Abstract

The present application relates to the field of semiconductor manufacturing technologies, and in particular to a method and an apparatus for automatically processing wafers. The method for automatically processing the wafers includes the following steps: providing several wafers, wherein the wafers operate on a primary path, and the primary path is a path for forming semiconductor structures on the surfaces of the wafers; determining whether there is a need for detecting defects of the wafers, and if yes, automatically switching an operating path of the wafers to a secondary path; detecting the defects of the wafers in the secondary path; and determining whether the defect detection on the wafers is finished, and if yes, automatically switching the operating path of the wafers to the primary path. The application makes it possible to automatically detect the defects of the wafers with different SWR conditions, thereby improving the automation degree of machines.
