Yunqi Capital | "Weichong Semiconductor" Closes Tens of Millions in Series A+ Funding

Recently, Weichong Semiconductor, a Yunqi Capital portfolio company specializing in semiconductor metrology and inspection equipment, completed a tens-of-millions-of-yuan Series A+ funding round. The round was jointly invested by Jinyu Maowu, Guanggu Semiconductor Industry Investment, and Saina Capital. The proceeds will be used for R&D, market expansion, and team building.

Yunqi Capital has always focused on "technology innovation, industrial empowerment." Advanced intelligent manufacturing industries, including semiconductors, represent one of our key areas of sustained investment. We believe domestic companies have the capacity and potential to lead technological transformation in the semiconductor space, and we look forward to seeing Weichong Semiconductor achieve even more.

The following is adapted from "Weichong Semiconductor."

Founded in 2021, Weichong Semiconductor was initiated by a leading overseas-returned semiconductor technical team and co-founded with seasoned domestic scientists and engineers. The company is grounded in frontier wafer inspection technologies and is committed to becoming a world-class semiconductor inspection equipment developer and manufacturer. Weichong Semiconductor's self-developed second-harmonic generation, thermal wave, and other equipment enable non-contact, non-destructive, in-line, rapid internal inspection of wafers, with precise identification and localization of wafer defects — delivering significant value to customers across R&D, ramp-up, and mass production stages, while providing new momentum for transformative change in the semiconductor front-end inspection industry. In addition, the company's new equipment model was completed and shipped by the end of 2024. Currently, all three equipment models have entered leading domestic mainstream customers and received high recognition.

Weichong Semiconductor founder, chairman, and CEO Chongji Huang said:

2024 was a year full of challenges. Both the semiconductor metrology and inspection market and the venture capital fundraising environment were extraordinarily difficult — every step forward was fraught with obstacles. Yet it was in these circumstances that Weichong Semiconductor successfully completed its Series A+ round. This is not only an important milestone in the company's development but also powerful proof of our persistence and hard work. We deeply understand that behind every financing round lies not only our shareholders' trust in Weichong but also their expectations and belief in China's independent semiconductor innovation.

Over the past year, the semiconductor industry has undergone accelerated technological iteration and profound shifts in market demand, while fundraising uncertainty has brought unprecedented challenges to startups. Yet the Weichong team has consistently upheld our original aspiration of "building greatness from the finest foundations." With multiple equipment models firing on all cylinders, we have continued to break through in wafer defect inspection — a "chokepoint" technology area — meeting customer needs and continuously empowering our clients!

The completion of this funding round is an affirmation of our past efforts and an expectation for the future. We will fully deploy this capital into new product R&D, equipment mass production, customer support, market expansion, and team building, continuously enhancing our technical capabilities and product competitiveness.

The development of China's semiconductor industry is a long and arduous journey. Weichong Semiconductor will remain true to our original aspiration, driven by innovation and grounded in our products, continuing to dig deep in the semiconductor metrology and inspection field. We believe that with unwavering effort, we will surely contribute more to the independent and controllable development of China's semiconductor industry. To all friends who have followed and supported Weichong, thank you — let us join hands and forge ahead toward higher goals! Be Aspiring!
