Micro-LED Firm Secures ¥200M for AI Glasses Tech

Qiu Shui Semiconductor, a pioneer in Micro-LED display technology, has successfully closed a significant funding round, amassing nearly 200 million RMB (approximately $27.6 million USD). This capital infusion, comprising Pre-A and Series A financings, was spearheaded by Zhaohui Capital, with substantial backing from Tongshang Fund, Shengyu Investment, Ningbo Talent Development Fund, Jiayi Venture Capital, Yongxian Technology, Shuzhi Guangxin, and Xingtang Capital. The company's strategic financial advisor throughout this process was Xingtang Capital.

The newly acquired funds are earmarked for the construction of an 8-inch hybrid bonding mass production line in Ningbo High-tech Zone, alongside continued investment in research and development. Established in November 2022, Qiu Shui Semiconductor focuses on Micro-LED micro-display chips and modules, targeting applications such as digital automotive lighting, AR glasses, and micro-projection. The company recently relocated its headquarters from Suzhou to Ningbo, signaling a strategic shift towards enhanced manufacturing capabilities.

Micro-LED technology is widely recognized as the next frontier in display innovation, yet its widespread adoption has been hampered by production challenges at the chip level. Industry projections indicate a substantial market for AR/VR headsets and AR glasses, with shipments expected to exceed 14 million units by 2025. However, the segment of AR glasses with advanced display functionalities remains nascent, accounting for less than one million units. Similarly, the automotive sector, particularly for adaptive driving beam (ADB) headlights, is seeing increasing adoption of Micro-LED pixel modules, with market penetration anticipated to reach 21.6% by 2029, as evidenced by implementations from manufacturers like Porsche. The primary bottleneck for both these burgeoning markets is the difficulty in achieving scalable chip production.

Qiu Shui Semiconductor's breakthrough lies in its proprietary, damage-free chip architecture. Unlike conventional methods that etch light-emitting materials on 4-inch sapphire substrates, causing significant efficiency degradation and yield issues, the company employs an innovative approach that bypasses this destructive step. By integrating an 8-inch silicon substrate with a hybrid bonding 3D packaging process, Qiu Shui Semiconductor achieves chip yields exceeding 6N, narrows the light emission angle from \u00b160\u00b0 to \u00b110\u00b0, and expands the operating temperature range to over 140\u00b0C. This advancement is crucial for overcoming the limitations that have previously hindered mass production.

The company has already introduced its 0.61-inch digital automotive lighting chips, successfully completing customer validation. Furthermore, a single-color green chip for AR applications is slated for release this year. Jiang Zhenyu, founder of Qiu Shui Semiconductor, believes that while monochromatic green chips can serve specific use cases like smart glasses for translation or navigation, achieving full-color Micro-LED displays is essential for the technology's "iPhone moment." He highlights that traditional red Micro-LED chips suffer over 97% light efficiency loss due to etching damage, a problem his company's damage-free technology aims to solve. Qiu Shui Semiconductor anticipates a significant breakthrough in colorization technology by year-end.

In the competitive Chinese Micro-LED chip sector, Qiu Shui Semiconductor adopts a fab-lite model, managing its critical hybrid bonding process in-house due to the lack of mature foundry services, while outsourcing other manufacturing steps to established semiconductor foundries. This approach allows for faster time-to-market compared to integrated device manufacturers (IDMs) who build entire production lines. The company is on track to bring its 8-inch hybrid bonding production line online by October this year, projecting a monthly output of thousands of 8-inch wafers, translating to over 10 million Micro-LED chips annually. Their advanced hybrid bonding vertical stacking architecture, capable of interconnecting light and electrical chips at a 3.75-micrometer pixel pitch, rivals cutting-edge processes like Huawei's recently announced 'Tao Ding Law'.

The leadership team is highly experienced, with founder Dr. Jiang Zhenyu bringing 15 years of expertise in semiconductor optoelectronic materials and devices from institutions like Penn State University, and prior roles at major industry players. His co-founder possesses eight years of entrepreneurial experience in high-power LED automotive lighting. Key team members have backgrounds at industry giants such as Huawei HiSilicon, YMTC, and Intel, contributing deep knowledge in hybrid bonding and advanced packaging.
