As semiconductor manufacturing progresses towards 3nm and lower process technologies, the processing accuracy of wafers has been enhanced to the nanometer level, presenting unprecedented challenges to equipment performance. Huzhou PrimTech Semiconductor Co., Ltd., relying on its independently developed precision motion platform, wafer alignment platform, ceramic fork, and wafer transfer system, has established a complete nanometer-level technology matrix. This not only fills the gap in domestic high-end semiconductor equipment but also drives global semiconductor manufacturing towards higher precision and efficiency. 

Core technology breakthrough: From wafer alignment to precise transfer 

The wafer alignment station is a crucial equipment in the semiconductor lithography process. It uses high-precision optical sensors and laser measurement technology to continuously monitor the position deviation of the wafer and automatically correct it through a fine-tuning mechanism, ensuring that the wafer is in the optimal position in the processing center. This technology significantly improves the integration and yield of chips, and is widely used in high-end lithography machines and etching machines. Prim's alignment station adopts an air-floating rotating shaft design, eliminating the friction loss caused by traditional mechanical contact and achieving nanometer-level positioning accuracy, providing a reliable guarantee for processes below 3nm. 

The ceramic disc fork, as the core component of the wafer loading system, its material and structural design directly affect the transmission stability of the wafer. The ceramic disc fork of Prim uses high-purity zirconia ceramic, which has the characteristics of high temperature resistance and corrosion resistance. At the same time, through the three-point edge clamping design, it avoids the deformation or damage of the wafer during the transmission process. This adaptive clamping structure is not only compatible with different sizes of wafers, but also significantly reduces the risk of manual intervention. 

The wafer transfer system is the "glue" that connects various stages in the semiconductor production line. It uses pneumatic or electric transmission devices to precisely transfer wafers from one process to another. Prim's EFEM (Equipment Front-end Module) transfer system integrates a robotic arm and multiple positioning devices, combined with intelligent recognition technology, to monitor the wafer status in real time and ensure zero errors during the transfer process. This system has increased production efficiency by 20%-30% and reduced the wafer damage rate. 

The synergy of the technology matrix: From the laboratory to mass production 

Prim's nanoscale technology matrix is not isolated but achieves collaborative optimization through precise motion platforms. For instance, during wafer calibration, the alignment platform and the air-floating motion platform are linked. Real-time data is provided by laser sensors, and the control system automatically adjusts the motion trajectory to ensure the absolute accuracy of the wafer during the processing. This collaborative design not only shortens the production cycle but also reduces equipment maintenance costs. 

At the production level, Prim's wafer loading system is closely integrated with the ceramic disc fork. Through modular design, it enables rapid model changes. For instance, in a 12-inch wafer production line, the system can automatically identify the wafer size, adjust the clamping force and transmission speed, ensuring efficient processing of different specifications of wafers. This flexibility allows Prim's equipment to adapt to the diverse requirements ranging from 8-inch to 12-inch wafers. 

Market Applications and Industry Impact 

Prim's technology has been widely applied in fields such as semiconductors, precision optics, and military industries. In semiconductor manufacturing, its equipment is used in key processes such as lithography, etching, and ion implantation, and its customers include first-tier manufacturers like Huawei and SMIC. For instance, in the production of 3nm chips, Prim's wafer alignment system achieves nanometer-level calibration, controlling the lithography and etching errors within ±0.5nm, significantly enhancing the performance of the chips. 

In the field of precision optics, Prim's precision motion platform is used in the manufacturing of laser interferometers and microscopes. Its nanometer-level positioning accuracy ensures the perfect alignment of optical components. In the military field, the high reliability and anti-interference capability of the equipment make it an ideal choice for missile guidance systems and radar components. 

Future Outlook: Building a Global Semiconductor Ecosystem 

With the rapid development of AI and IoT technologies, the demand for semiconductors continues to grow. Prim is building a more open innovation platform through technological iterations and ecological collaborations. For instance, the company collaborates with institutions such as the Chinese Academy of Sciences and Zhejiang University to develop the next-generation intelligent calibration algorithms, further enhancing the autonomous decision-making capabilities of equipment. 

In terms of global layout, Prim has established R&D centers in the United States and Europe, and through local teams, it can quickly respond to market demands. At the same time, the company actively participates in the formulation of international standards, promoting Chinese semiconductor equipment to enter the global stage.
