Rapid Semiconductor Inspection with Microscope Contrast Methods

Uncover critical details during semiconductor quality control with efficiency and reliability using light microscopy

Images of the same area of a processed wafer taken with standard (left) and oblique (right) brightfield illumination using a Leica compound microscope. The defect on the wafer surface is clearly more visible with oblique illumination. Processed_wafer_standard_and_oblique_brightfield_illumination.jpg

Semiconductor inspection during the production of patterned wafers and ICs (integrated circuits) is important for identifying and minimizing defects. To increase the efficiency of quality control in the early stages of production and to ensure reliable IC chip performance, microscopy solutions should combine different contrast methods that provide complete and accurate information about different defects.
