In the microscopic world of semiconductor manufacturing, every nanometer-level precise operation relies on the strong support of core equipment. Huzhou Prim Semiconductor Co., Ltd., as an innovative leader in the domestic semiconductor equipment field, is building a high-precision and high-efficiency manufacturing foundation for the global semiconductor industry with its independently developed core equipment such as wafer transfer systems, ceramic wafer forks, wafer alignment tables, and precision motion stages, and is promoting the steady progress of China's semiconductor industry towards high-end and intelligent development. 

I. Wafer Transfer System: Unblocking the Efficient Channel of Wafer Manufacturing 

The wafer transfer system is the "logistics hub" in the semiconductor manufacturing process, responsible for precisely and quickly transporting wafers between various processes. Its stability and efficiency directly affect the production yield and capacity of chips. As the semiconductor industry advances to 7nm, 5nm, and even more advanced processes, the requirements for the accuracy and speed of wafer transfer become increasingly strict. 

The wafer transfer system developed by Prim integrates multi-axis linkage control and visual positioning technology, achieving micron-level positioning during the wafer handling process. The intelligent path planning algorithm equipped in the system can automatically adjust the handling path based on the real-time demands of the production process, avoiding interference between equipment and reducing the wafer handling cycle time to 80% of the industry average. Meanwhile, the system's built-in self-diagnosis module can monitor the equipment's operational status in real time, issue early warnings for potential faults, and ensure the continuous and stable operation of the production line. Currently, this system has been successfully applied in the production lines of leading domestic enterprises such as SMIC and Eswin Semiconductor, becoming a key device for enhancing chip manufacturing efficiency. 

II. Ceramic Plate Fork: The "Invisible Hand" for Precise Picking 

During the wafer handling process, the wafer fork is the component that directly contacts the wafer. Its material and design precision determine the safety and grasping accuracy of the wafer. Traditional metal wafer forks are prone to static reactions with wafers, causing surface damage to the wafers, while ordinary plastic wafer forks cannot meet the high-precision and high-cleanliness usage requirements. 

Prim's ceramic wafer forks are made of silicon nitride ceramic material, which features an extremely low coefficient of thermal expansion, extremely high hardness, and excellent insulation performance. This material can prevent static electricity from damaging wafers and maintain dimensional stability during repeated grasping. The R&D team has precisely controlled the flatness of the wafer forks to the micrometer level through advanced processing techniques, ensuring perfect contact with the wafer surface and avoiding wafer breakage due to uneven force. Additionally, the surface of the wafer forks has undergone special polishing treatment, with a roughness of only 0.02 micrometers, effectively reducing the adsorption of particle impurities and meeting the strict cleanliness requirements of semiconductor manufacturing. Currently, this ceramic wafer fork has become a standard component of Prim's wafer transfer system, providing reliable protection for the safe handling of wafers. 

III. Wafer Alignment Stage: The "Precise Eyes" for Nanometer-level Positioning 

Wafer alignment is a crucial process in chip manufacturing, which requires precise alignment of the marks on the wafer with the reference positions of equipment such as photolithography machines. The positioning accuracy directly determines the quality of chip photolithography. With the continuous reduction of chip manufacturing processes, the alignment accuracy requirement has been raised from the micrometer level to the nanometer level. 

Prim's wafer alignment table adopts an air-floatation rotating shaft and a nano-interference feedback compensation system, achieving a positioning accuracy of 50 nanometers and a repeat positioning accuracy of 35 nanometers, reaching the international advanced level. The system is equipped with a high-speed visual imaging module that can capture the position information of the wafer mark within 0.1 seconds and calculate the deviation through real-time algorithms, driving the air-floatation rotating shaft for high-precision adjustment. To counteract the influence of environmental temperature, vibration and other factors on positioning accuracy, the R&D team has also equipped the alignment table with an active vibration isolation system and a temperature compensation module, ensuring stable positioning accuracy in complex production environments. Currently, this alignment table has been applied in semiconductor lithography equipment and metrology equipment, providing core support for the high-precision manufacturing of chips. 

IV. Precision Motion Stage: The "Spatial Conductor" of Microscopic Operations 

Precision motion stages are core components of high-end equipment such as lithography machines and gene sequencers, and are known as the "space conductors" of the microscopic world. Their performance directly determines the processing and measurement accuracy of the equipment. For a long time, China has relied on imports for high-precision precision motion stages, which has become a bottleneck restricting the development of domestic high-end equipment. 

In 2023, Dr. Wang Xiaoxing, the founder of Prim, led his team to venture into this "hardcore" field, conducting cross-disciplinary research in areas such as precision mechanics, automatic control, and photoelectric integration. The team successfully overcame key technical bottlenecks in ultra-precision displacement control and nanometer positioning feedback. The air-floatation static pressure technology and nanometer interferometry feedback compensation system they developed achieved a positioning accuracy of 50 nanometers and a repeat positioning accuracy of 35 nanometers. Based on this, the team further advanced the positioning accuracy of the new generation of products to within 30 nanometers and increased the response speed by 40% through the massive data and real feedback from the production line, thus achieving a virtuous cycle of "mass production feeding back to R&D". Currently, Prim's precision motion stages have been applied in multiple fields such as semiconductor lithography equipment, gene sequencers, and laser precision processing, becoming a "key component" for domestic high-end equipment to reach international advanced levels. 

V. Innovation-driven: A Splendid Transformation from Laboratory to Industrialization 

The rapid development of Prim is inseparable from the support of Huzhou, a hotbed for entrepreneurship. With the support of the local government, the company has quickly completed the transformation from laboratory technology to industrialization. The company has established a research and development and production base in the West Lake Science and Technology Park in Changxing County, Huzhou, equipped with a thousand-level clean laboratory and ultra-precision processing workshop, providing a solid guarantee for the research and development and mass production of core equipment. 

Meanwhile, Prim adheres to the collaborative innovation of "industry-university-research-application", and has established long-term cooperative relationships with research institutions such as the Institute of Automation of the Chinese Academy of Sciences, rapidly converting the cutting-edge technologies from laboratories into industrial products. By 2025, the company's revenue exceeded 60 million yuan, with a research and development investment ratio of over 20%, reaching 12 million yuan, forming a virtuous cycle of "research and development - mass production - further research and development". Today, Prim not only has a foothold in the domestic semiconductor equipment market but also plans to expand its products to the global market, striving to gain a say in the global high-end motion control field. 

Amid the wave of domestic substitution in the semiconductor industry, Huzhou Prim Semiconductor Co., Ltd. is leveraging its robust technological strength to break the foreign technological monopoly and contribute to the rise of China's semiconductor industry. In the future, with the continuous innovation and breakthroughs of more core equipment, Prim will continue to lead the new direction of semiconductor precision manufacturing and drive China's semiconductor industry towards higher precision and higher efficiency.
