The purpose of the instrument:

The ZXGP-800 research grade large platform silicon wafer microscope is mainly used for observing semiconductor silicon wafers. It can produce high-definition images with strong stereoscopic effect, clear and wide imaging, long working distance, and a large field of view and corresponding magnification. Equipped with a high pixel digital camera, it can clearly see the micro morphology distribution of the "pyramid" of silicon wafers and provide defect analysis services for silicon wafers It is a commonly used microscope for solar cell silicon wafers and has a wide range of applications in the semiconductor industry.

The large platform silicon wafer inspection microscope can observe dislocations, scratches, and edge breaks that are difficult to observe with the naked eye on solar cell silicon wafers; It can also analyze the impurities and residual components of silicon wafers Impurities include particles, organic impurities, inorganic impurities, metal ions, silicon powder dust, etc., which can cause discoloration, bluing, blackening and other phenomena in the silicon wafer after grinding, making the grinding wafer unqualified. It is a common instrument for quality control in solar cell silicon wafer production enterprises.

2、 System Introduction

The large platform silicon wafer microscope system organically combines traditional optical instruments with computers (digital cameras) through photoelectric converters. It can observe real-time dynamic images on the computer (digital camera) display screen and edit, save, and print the required images.
