About Shanghai Hidden Crown Semiconductor Technology

Shanghai Hidden Crown Semiconductor Technology (also known as YiNGUAN Semiconductor) was formally established in January 2019 by a team from Fudan University focused on ultra-precision motion and measurement. The company's legal representative is Wu Liwei, and its founder and chief scientist is Yang Xiaofeng. From its inception, the firm has aimed to become a key domestic supplier of critical components for semiconductor manufacturing equipment.

The company focuses on the research, development, and production of high-precision motion control systems and core components for the semiconductor industry. It serves clients in the semiconductor manufacturing, measurement, and advanced packaging sectors, as well as providing solutions for industries like lasers, optoelectronics, and intelligent manufacturing. Its business model revolves around designing, manufacturing, and selling these specialized components and systems to equipment makers, addressing the need for domestic alternatives to imported parts.

Hidden Crown's product portfolio is organized into five main lines: precision motion platforms, special motors, piezoelectric products, drive and control products, and precision components. Specific offerings include micro-step motor modules, voice coil motors, piezoelectric actuators, vacuum and electrostatic chucks, and vacuum feedthrough flanges. These components are crucial for the precise positioning and control required in semiconductor fabrication and inspection processes. The company operates R&D and production bases in Shanghai and Suzhou, with facilities equipped for assembly, testing, and debugging of its high-precision products.
