                                                                                        6/8'' Wafer Surface Warpage and Nanotopography Measurement Equipment (WGT-V)

Wafer geometry measurement equipment plays a crucial role in wafer manufacturing, not only in measuring the geometric parameters of wafers but also in ensuring the quality and reliability of the entire manufacturing process. Firstly, wafer manufacturing is a highly precise process, where even minor geometric deviations can lead to issues in subsequent chip manufacturing, such as circuit connectivity failure or performance degradation. Therefore, by accurately measuring parameters like diameter, thickness, and flatness of wafers, manufacturers can detect potential issues early and correct them promptly to ensure the quality and performance of the final product.

Quality control is particularly important in wafer manufacturing, as wafers serve as the foundational material for chip manufacturing, directly impacting chip performance and reliability. By using wafer geometry measurement equipment, manufacturers can effectively monitor various stages of the manufacturing process, reduce deviations and defects, lower scrap rates, and enhance production efficiency.

Key Features and Advantages:

Wide Application: Suitable for wafer manufacturing, wafer-level packaging, and semiconductor process equipment development and manufacturing fields, meeting the needs of different industries;
