Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of photoetching machine, especially a photoetching machine lens coating optimization tool. BACKGROUND

[0002] The core function of photoetching machine lens coating is to significantly improve the reflectivity and transmittance of the lens, thereby optimizing the clarity of the photoetching pattern and effectively prolonging the service life of the coating. In the complex and precise photoetching process, this technology can greatly reduce the loss of light and ensure that more light accurately reaches the surface of the silicon wafer, thereby directly enhancing the efficiency and accuracy of photoetching.

[0003] It is worth noting that although models such as NIKIN6 / 7 / 8 have been used for as long as 30 years, their performance is gradually limited, mainly due to the increasingly serious photoetching and fogging phenomenon on the lens surface, which not only leads to a significant drop in light transmittance, but also may cause uneven light transmittance distribution.

[0004] In the coating process of photoetching machine lens, physical vapor deposition technology is widely used due to its high efficiency and reliability. This technology usually involves depositing a layer of molybdenum film on a high-purity quartz substrate first through chemical vapor deposition technology, then carefully stacking multiple layers of silicon film on it, and then continuing to stack multiple layers of molybdenum film on the silicon film to form a complex multilayer film structure, thereby achieving efficient reflection or transmission of specific band light.

[0005] However, the coating process is not easy. Since multiple coatings are required, and the lens usually contains an effective area and an ineffective area, film layers will inevitably be deposited in the ineffective area during the coating process, which poses a considerable challenge to subsequent cleaning work. In addition, the photoetching machine lens needs to be accurately positioned and angled before photoetching to ensure the accuracy of light source distribution. However, on traditional coating equipment, there is often a lack of mechanisms for precise adjustment of photoetching machine lenses, which may result in unsatisfactory light transmittance of the coated lens.
