On August 1, the 2025 Advanced Lithography Technology Seminar was grandly held in Suzhou. The meeting brought together hundreds of experts and entrepreneurs in the lithography industry. More than a dozen in-depth reports were presented in turn. Everyone enthusiastically discussed the latest technological progress, process optimization, and future development directions of the lithography industry.

       The atmosphere at the exhibition was hot

In recent years, with the rapid development of emerging technologies such as artificial intelligence, big data, the Internet of Things, and 5G communications, the demand for high-performance chips has shown explosive growth. As a key material in these fields, the importance of photoresist is self-evident.

                                                                                             Yifu participated in the entire meeting, arranged a booth at the conference site, demonstrated our sanding technology and application in the lithography industry, and interacted with many guests and companies, attracting the attention of many guests and companies. There was an endless stream of customers consulting on-site, and cooperation intentions were established with many industry experts and enterprises.

      Several major advantages of Yifu vertical sand mill in the photolithography industry:

     Precise particle size control: In photoresist production, particle size control is the key. The vertical sand mill can use zirconium beads as low as 0.03mm, which can grind particles to ultra-fine nanometer levels and ensure uniform particle size distribution, meeting the requirements for high-precision particle size in photoresist production.

       Excellent grinding efficiency:The vertical sand mill adopts advanced grinding and separation technology, and uses the high-speed rotating grinding disc to drive the grinding media to powerfully grind the photoresist. It can reduce the particle size in the photoresist to the nanometer level in a short time, greatly improving the grinding efficiency. Compared with traditional grinding equipment, the grinding time of the vertical sand mill can be shortened several times, and the production efficiency is significantly improved.

        Good heat dissipation performance:A large amount of heat will be generated during the grinding process. If the heat cannot be dissipated in time, the performance of the photoresist will decrease. The vertical sand mill adopts an efficient heat dissipation system, which can dissipate heat in time to ensure that the grinding process is carried out at a stable temperature. This not only improves the quality of the photoresist, but also extends the life of the equipment.

       Pollution-free design:Photoresist has extremely high requirements for the cleanliness of the production environment, and any slight contamination may lead to a decrease in product quality. The vertical sand mill fully considers this factor in its design and adopts a fully enclosed grinding chamber and advanced sealing technology to effectively prevent the entry of external impurities. At the same time, the movement paths of the grinding media and photoresist during grinding are carefully designed to avoid contact with other parts of the equipment, further reducing the possibility of contamination.

       Easy to clean and maintain: Photoresist production requires extremely high cleanliness of equipment. Once impurities remain inside the equipment, it will affect the quality of the next batch of products. The vertical sand mill has a reasonable structural design and an automatic lifting design. The internal parts are easy to disassemble and clean, and can quickly and thoroughly remove residual materials to ensure the cleanliness of the equipment. At the same time, its maintenance is relatively simple, reducing the company's operating costs.

       Intelligent control: The vertical sand mill fully realizes intelligent control. Through advanced sensors and control systems, operators can monitor and adjust various parameters during the grinding process in real time to ensure the stability and consistency of the production process. At the same time, the intelligent control system can also monitor and diagnose the operating status of the equipment in real time, discover and solve potential problems in a timely manner, and improve the reliability and service life of the equipment.

In the field of semiconductors, as chip manufacturing processes continue to move towards smaller sizes, the performance requirements for photoresists are also getting higher and higher. The high-efficiency grinding and precise control capabilities of the Yifu vertical sand mill enable photoresist to meet higher technical standards and provide strong support for the development of semiconductor chips.

      Technological innovation and sustainable development

Yifu has always reserved research and development capabilities in the grinding of photoresist materials. It has cooperated with many companies to complete high-standard research and development. It has also established cooperation with many leading companies on the production line and has achieved very good results, which has been unanimously recognized by everyone! I believe that in the future, with the continuous advancement of technology, Yifu vertical sand mill will work hand in hand with the photoresist industry to create a more brilliant tomorrow.
