Overview of the 2025 semiconductor epitaxial wafer market

For example, Lione Microelectronics—a manufacturer of semiconductor silicon wafers—has recently made continuous progress in the 12-inch silicon wafer segment. In February 2025, Lione Microelectronics signed an agreement with the Management Committee of Jiaxing South Lake High-Tech Industrial Park to invest RMB 1.23 billion in constructing a project titled “Annual Production of 960,000 12-inch Silicon Epitaxial Wafers.” Upon full completion and ramp-up, the project is expected to achieve an annual production capacity of 960,000 12-inch silicon epitaxial wafers. The construction period is projected to last 5–8 years and will be implemented within the factory premises of Jinruihong Microelectronics (Jiaxing) Co., Ltd.—a company previously acquired by Lione Microelectronics. 5. Policy Support Globally, the development of the epitaxial wafer industry is strongly supported by policies enacted by major countries and regions, thereby promoting technological advancement and industrial scale expansion. The United States, through initiatives such as the CHIPS and Science Act, provides financial subsidies and tax incentives for advanced semiconductor manufacturing, power devices, and compound semiconductor material R&D and capacity expansion—focusing particularly on epitaxial technologies related to silicon, silicon carbide (SiC), and gallium nitride (GaN). The European Union’s European Semiconductor Plan explicitly aims to enhance indigenous chip design and manufacturing capabilities, supporting innovation in advanced epitaxial materials and processes—especially for power semiconductors, LEDs, and optical communications. Japan, South Korea, and Taiwan employ industrial funds, technology innovation alliances, and enterprise subsidies to safeguard the global supply-chain competitiveness of their domestic epitaxial wafer manufacturers. China’s policy support is especially intensive, with domestic substitution serving as a critical industry driver. Below are recent Chinese regulations relevant to the epitaxial wafer sector: Release Date Document Title Main Content / Key Focus Areas 2021-03-11 "The 14th Five-Year Plan for National Economic and Social Development and Long-Range Objectives Through the Year 2035" of the People’s Republic of China Formulation of strategic scientific programs and engineering projects in areas vital to national security and development; R&D of integrated circuit (IC) design tools, key equipment, and high-purity target materials; breakthroughs in advanced IC process technologies and specialty processes (e.g., IGBTs, MEMS); upgrading of advanced memory technologies; development of wide-bandgap semiconductors such as silicon carbide and gallium nitride. 2021-06-01 "Guiding Opinions on Accelerating the Cultivation and Development of High-Quality Manufacturing Enterprises," jointly issued by the Ministry of Industry and Information Technology, Ministry of Science and Technology, Ministry of Finance, Ministry of Commerce, State-owned Assets Supervision and Administration Commission, and China Securities Regulatory Commission Formation of innovation consortia or technology innovation strategic alliances; collaborative innovation; focused攻关 (technical breakthroughs) on core components, basic electronic components, foundational software, basic materials, fundamental processes, high-end instrumentation and equipment, integrated circuits, and cybersecurity—covering key core technologies, products, and equipment, along with demonstration applications. 2021-12-12 "Notice of the State Council on Issuing the 14th Five-Year Plan for Digital Economy Development" Enhancing supply capabilities for foundational hardware and software, core electronic components, critical raw materials, and production equipment; strengthening self-sufficiency in key products; implementing industrial chain reinforcement and gap-filling initiatives; fostering technology integration and product innovation for diversified application scenarios; building robust supply chains for key industries—including 5G, integrated circuits, new-energy vehicles, artificial intelligence, and industrial internet.

Wolfspeed receives a $1.5 billion conditional loan commitment from the U.S. Department of Defense

Power semiconductor manufacturer Wolfspeed announced it has received a conditional loan commitment of up to $1.5 billion from the U.S. Department of Defense (DoD), intended to expand domestic silicon carbide (SiC) material and power device manufacturing capacity. Following the announcement, the company’s stock surged 27% after hours. Wolfspeed specializes in SiC chips, which deliver higher energy efficiency and are widely used in high-power conversion applications such as electric vehicles, solar inverters, and industrial power systems. This 30-year loan originates from the DoD’s Office of Strategic Capital and, according to the company, will help optimize its capital structure and strengthen its financial position. In addition to expanding SiC production, the funds will also support upgrades to gallium nitride (GaN) technology—targeting next-generation communication infrastructure and electronic warfare systems—as well as research and development of radiation-hardened technologies. Whether this funding ultimately materializes remains subject to several prerequisites, including completion of due diligence, finalization of the definitive agreement, and approval by relevant government authorities. Under the terms of the agreement, Wolfspeed must issue warrants to the DoD, granting it the right to purchase up to 7.5% of the company’s fully diluted equity.
