•  The lens is made of ultra – low – dispersion glass materials to minimize chromatic aberration and provide sharp images. It also includes a series of mirrors and filters to direct and manipulate the light path. The filters can be adjusted to select specific wavelengths of light for different inspection requirements.
• Illumination System: Equipped with a high – intensity LED or laser illumination source. The illumination can be adjusted in terms of intensity, angle, and wavelength. For example, it can provide bright – field, dark – field, and oblique illumination modes to enhance the visibility of different types of defects on the wafer surface. The maximum illumination intensity is [X] lux, and the wavelength range can be tuned from [Y] nanometers to [Z] nanometers.
• Image Sensor: Uses a high – resolution CCD or CMOS image sensor with a pixel size of [A] micrometers and a total number of pixels of [B] million. The sensor has a high dynamic range and low noise characteristics, enabling it to capture clear images even under varying lighting conditions.
• Optical Resolution: Can achieve an optical resolution of [C] micrometers, allowing it to detect very small defects on the wafer surface. The field of view of the optics module is [D] square millimeters, which determines the area of the wafer that can be inspected in a single shot.

Functional Features:

• High – Speed Imaging: The optics module is designed to capture images at high frame rates, up to [E] frames per second. This enables fast inspection of the entire wafer surface, reducing the inspection time and increasing the throughput of the inspection system.
• Auto – Focus and Auto – Alignment: Incorporates an auto – focus mechanism that can quickly and accurately adjust the focus of the objective lens to ensure that the wafer surface is in sharp focus. It also has an auto – alignment function to align the optics module with the wafer, eliminating any misalignment errors that could affect the inspection results.
• Real – Time Image Processing: The module is integrated with on – board image processing capabilities. It can perform basic image enhancement operations such as contrast adjustment, noise reduction, and edge detection in real – time. This helps in improving the quality of the captured images and facilitating faster defect detection.
• Compatibility: Designed to be compatible with different types of semiconductor wafer inspection systems. It can be easily integrated into existing systems or used as an upgrade component to improve the inspection performance.

Application Scenarios:

• Front – End Wafer Inspection: In the front – end of semiconductor manufacturing, this optics module is used to inspect bare wafers for surface defects such as scratches, pits, and contamination. Early detection of these defects can prevent them from being transferred to subsequent processing steps, reducing scrap rates and improving product quality.
• Patterned Wafer Inspection: For patterned wafers, the module can detect defects in the circuit patterns such as missing or extra features, short – circuits, and open – circuits. It helps in ensuring the integrity of the semiconductor devices and identifying any process – related issues that may have caused the pattern defects.
• In – Line Inspection: During the semiconductor manufacturing process, the optics module can be used for in – line inspection of wafers at various stages. This allows for real – time monitoring of the process quality and timely adjustment of the process parameters to prevent the production of defective wafers.
