The global leader in GaN power semiconductor market share, from NASA scientists to leaders in China’s third-generation semiconductor sector, Dr. Luo Weiwei has led Innosilicon on a hardcore tech entrepreneurial path.
On December 30, 2024, Innosilicon successfully listed on the Hong Kong Stock Exchange, becoming the first stock in the “third-generation semiconductor” category. Founded in 2017, the company has risen to become the global leader in the GaN power semiconductor market in just eight years, holding a 42.4% market share as of 2023. Innosilicon’s listing is not only a victory for the capital market but also signifies China’s important position in the critical field of third-generation semiconductors. As the world’s first company to achieve mass production of 8-inch silicon-based GaN wafers, Innosilicon is changing the competitive landscape of global power semiconductors.
01 Company Journey: From Technological Breakthrough to Capital Recognition
Innosilicon was established in Suzhou on July 21, 2017, by Dr. Luo Weiwei, who worked at NASA for 15 years. She returned to China to start a business, establishing companies in Zhuhai and Suzhou, and pushing for breakthroughs in 8-inch silicon-based GaN wafer technology. In just a few years, Innosilicon achieved leapfrog development. By August 2020, its GaN power chip shipments reached one million; by October 2022, it surpassed one hundred million; and by December 2023, total shipments exceeded five hundred million. The year 2024 marks the capital year for Innosilicon. The company submitted its listing application to the Hong Kong Stock Exchange on June 12, 2024, and successfully went public on December 30 of the same year, with an opening market value exceeding HKD 27 billion. Of the net proceeds from this IPO, 60% will be used to expand 8-inch GaN wafer production capacity, aiming to increase monthly production from 12,500 wafers to 70,000 wafers over the next five years.
02 Technical Strength: Global Leading Hard Technology
Innosilicon’s core competitiveness stems from its technological breakthroughs. The company is the world’s first to achieve mass production of 8-inch silicon-based GaN wafers. Compared to traditional 6-inch wafers, the 8-inch technology increases the number of die per wafer by 80% and reduces the cost of individual devices by 30%, resulting in significant economic benefits. As one of the few GaN companies adopting the IDM (Integrated Device Manufacturing) model globally, Innosilicon covers the entire process from chip design, wafer manufacturing, to packaging and testing. Although this model requires substantial initial investment, once scaled, it will create a competitive barrier that is difficult to replicate. As of December 2024, Innosilicon has accumulated 406 patents globally, including 331 invention patents, with an additional 387 patent applications pending. These patents cover key areas such as chip design, device structure, and wafer manufacturing. Particularly in terms of reliability, the company’s third-generation devices have passed 2000 hours of dynamic HTOL testing, with a lifespan exceeding 20 years at 175°C, meeting the demands of stringent application scenarios such as data centers.
03 Market Performance: Demand-Driven Rapid Growth
With the continuous rise in global demand for high-performance, low-power semiconductor technology, the GaN power semiconductor market is experiencing explosive growth. According to a forecast by Sullivan, the GaN power semiconductor market size is expected to grow from CNY 3.228 billion in 2024 to CNY 50.142 billion in 2028, with a compound annual growth rate of 98.5%. Innosilicon is fully benefiting from this market dividend. The company’s revenue surged from CNY 68.215 million in 2021 to CNY 590 million in 2023, with a compound annual growth rate of 194.8%. By the first half of 2024, revenue had reached CNY 386 million. The company’s products are widely used in various fields including consumer electronics, new energy vehicles, data centers, and renewable energy. It has established solid partnerships with smartphone manufacturers such as OPPO, vivo, and Xiaomi, as well as e-commerce companies like Anker and Ugreen. In high-end fields, Innosilicon has become the only Chinese local chip partner in NVIDIA’s 800VDC high-voltage direct current power supply architecture, marking its technical strength recognized by top international clients.
04 Ecological Layout: Vertical Integration and Horizontal Expansion
Innosilicon is actively building an industrial ecosystem. The company has two 8-inch silicon-based GaN production bases in Zhuhai and Suzhou, establishing the world’s highest capacity GaN wafer production line. In terms of industry chain cooperation, Innosilicon signed strategic cooperation agreements with United Automotive Electronics and Naxin Micro in 2025 to jointly develop GaN products for new energy vehicles. It has also partnered with Midea Group’s Weiling Motor and Kitchen Heating Division to promote the application of GaN technology in home appliances. The company is also laying out international R&D resources, establishing R&D teams in Europe, North America, and Asia. The European team focuses on device development and reliability assessment, the North American team focuses on product and driver chip design, while the Asian team is responsible for developing new technology platforms. This global layout enables Innosilicon to integrate global R&D resources while deeply cultivating the Chinese market, achieving effective synergy of “global technology + Chinese manufacturing”.
05 Challenges and Risks: Tests in Growth
As a technology-intensive and capital-intensive enterprise, Innosilicon faces multiple challenges. Financially, despite rapid revenue growth, the company still faced certain losses in 2023, with a net cash flow from operating activities of -CNY 336 million in 2024. In terms of technological competition, Innosilicon is in direct competition with international giants such as Infineon and Texas Instruments. In 2024, the company was also involved in a Section 337 investigation by the U.S. International Trade Commission, accused of infringing four patents. The semiconductor industry has distinct cyclical characteristics, and balancing capacity expansion with market demand is crucial. Innosilicon plans to increase monthly production from 12,500 wafers to 70,000 wafers, and this expansion speed must match market growth. Additionally, GaN technology itself is still evolving, requiring continuous high-intensity R&D investment. From 2021 to 2023, the company’s R&D expenditures were CNY 662 million, CNY 581 million, and CNY 349 million respectively, making it a key issue to balance short-term profitability with long-term investment.
06 Future Prospects: The Golden Path of Third-Generation Semiconductors
With the rapid development of AI technology and the booming new energy vehicle industry, the global demand for high-performance, low-power semiconductor technology continues to rise. GaN, as an outstanding representative of third-generation semiconductor materials, is reshaping the semiconductor industry landscape at an unprecedented speed. Innosilicon’s layout in cutting-edge fields such as the 800VDC architecture has already shown results. This architecture can increase the power of a single cabinet in data centers from 200kW to 1MW, reducing current by more than 15 times compared to traditional architectures and decreasing copper busbar usage by 45%, potentially lowering the total cost of ownership (TCO) of data centers by 30%. The company plans to allocate 20% of the IPO proceeds to R&D and expanding its product portfolio to increase the penetration of GaN products in the end market. This strategy will help Innosilicon maintain its leading position in the rapidly expanding market. As countries advance towards carbon neutrality goals, high-performance semiconductors will play a key role. The advantages of GaN devices in energy conversion efficiency provide broad application prospects in green energy fields such as photovoltaics and energy storage. Innosilicon plans to increase its monthly production from the current 12,500 wafers to 70,000 wafers over the next five years, demonstrating the company’s strong confidence in market prospects. With the booming development of AI, new energy vehicles, and renewable energy industries, the demand for high-efficiency power semiconductors will continue to grow. Leveraging its technological leadership and production scale advantages, Innosilicon is expected to capture the largest market share in this energy revolution. The next decade will be the golden period for third-generation semiconductor technology. As a leading enterprise in the global GaN field, Innosilicon not only represents China’s breakthroughs in high-end semiconductor manufacturing but will also drive innovation in power electronics technology globally.
