Yinguan Semiconductor

What Yinguan Semiconductor does

Yinguan Semiconductor (上海隐冠半导体技术股份有限公司) is a Shanghai-based precision motion control systems provider founded in 2019, serving China's semiconductor equipment industry. The company designs and manufactures ultra-high precision motion platforms (vacuum, air-floating, single-axis, XY, ZT, and multi-axis stages), specialized motors (voice coil, magnetic levitation, water-cooled), piezoelectric products (devices, drive control, materials, packaged actuators, motors, complete systems), and key components (vacuum chucks, electrostatic chucks and controllers, clean drag chains, vacuum fiber feedthroughs). Its wholly-owned subsidiary Yingguan Piezo (隐冠压电) extends the company's vertical integration from piezoelectric materials through to complete nano-motion stage systems — a full industry chain capability that is rare among domestic Chinese suppliers.

The company sells primarily to semiconductor equipment OEMs, wafer manufacturers, and advanced packaging equipment makers, with North HuaChuang (北方华创) named as a core hybrid bonding precision motion platform customer. Solutions span semiconductor inspection and measurement (electron beam inspection, overlay measurement, thin film measurement, nano-imprint lithography), wafer fabrication equipment, and advanced packaging (die attach, wafer thinning, hybrid bonding, wafer dicing, TCB thermal compression bonding). The company delivers one-stop customized solutions combining front-end R&D, preliminary design, after-sales service, and technical training under multi-year, quote-based B2B contracts. With 251-500 employees including approximately 100+ R&D personnel and a portfolio of 300+ patents (180+ invention patents) plus 30+ software copyrights, Yinguan generated a $13.8M financing round in November 2023 from CCB Investments, Clearstone Capital, Kunlun Capital, Edge Ventures, and Spinnotec, and was recognized in 2024 as a national-level 'Little Giant' enterprise by China's Ministry of Industry and Information Technology.
