Angkun Vision Technology

Angkun Vision Technology (Beijing) Co., Ltd. is a specialized manufacturer of optical measurement and inspection equipment, established in February 2017. The company was founded by Dr. Tiezhong Ma, who earned his bachelor's degree from Tsinghua University and a Ph.D. from the University of Minnesota. Dr. Ma, who previously founded the EDA company Empyrean Technology in 2007, launched Angkun Vision as his second entrepreneurial venture, bringing extensive experience in the semiconductor field.

The firm focuses on providing solutions for the compound semiconductor, optoelectronics, and integrated circuit industries. Its business model revolves around the design, research and development, and manufacturing of high-precision inspection equipment. Revenue is generated from the sale of these specialized machines to clients in the semiconductor manufacturing sector. The company operates R&D and production facilities in Beijing, Nanchang, and Hangzhou, serving a customer base that spans across China and international markets.

Angkun Vision's product portfolio is engineered to address various stages of semiconductor production. Key offerings include wafer defect inspection systems for both patterned and unpatterned wafers, such as the F2000 for front-end integrated circuit manufacturing and the E3500 for SiC material inspection. The company also produces equipment for measuring wafer morphology parameters like thickness, TTV, bow, and warp with its SPI300 system. A distinct capability lies in its use of proprietary AI and machine learning algorithms, which have been reported to increase inspection efficiency by over 30%. These systems are crucial for manufacturers of LED chips, compound semiconductors, and other integrated circuits to improve production yields by identifying microscopic defects.

The company has secured significant financial backing through multiple funding rounds, including a Series E round in March 2025 and a subsequent F round in July 2025. Notable investors include the China National Integrated Circuit Industry Investment Fund (also known as the Big Fund), Bite Fund, and SINO-IC Capital, underscoring strong confidence in its market position and technological capabilities. This financial support is intended to accelerate the development and production of advanced semiconductor inspection equipment.
