Detailed content
-
- This is achieved through the use of high – quality lenses and advanced optical design techniques.
- Illumination System: Equipped with a multi – wavelength illumination system that can provide different types of illumination, such as bright – field, dark – field, and polarized illumination. This enables the inspection system to detect a wide range of defect types under different lighting conditions.
- Field of View: The module has a large field of view of 20 mm x 20 mm, which allows for faster inspection of the wafer surface by covering a larger area in a single scan.
- Functional Features:
- High – Speed Imaging: It can capture images at a high frame rate of up to 100 frames per second. This enables real – time inspection of the wafer as it moves through the inspection system, improving production efficiency.
- Low Distortion: The optical design minimizes image distortion, ensuring that the detected defects are accurately represented in the captured images. This is crucial for precise defect classification and analysis.
- Environmental Adaptability: The module is designed to operate in the cleanroom environment of a semiconductor fab, with features to prevent contamination and withstand the vibrations and temperature variations commonly found in such settings.
- Application Scenarios:
- Inline Wafer Inspection: Integrated into inline wafer inspection systems in semiconductor manufacturing lines. It continuously inspects wafers during the production process, allowing for early detection of defects and timely corrective actions to prevent the production of defective devices.
- Quality Control in Semiconductor Packaging: Used in the quality control process during semiconductor packaging to inspect the die and the package surface for defects before final assembly, ensuring the reliability of the packaged semiconductor devices.
