Silicon EPI wafers are essential to 5G infrastructure because they enable the manufacturing of high-frequency, high-performance semiconductor devices - such as RF amplifiers and switches - that are necessary for the efficient and rapid transmission of 5G signals. For example, in May 2023, Telefonaktiebolaget LM Ericsson, a Sweden-based information and communication technology company, projected that 5G mobile subscriptions would reach 4.624 billion by 2028, up from 1.481 billion in 2023. Therefore, the development of 5G infrastructure is propelling growth in the silicon EPI wafer market.

Major companies in the silicon EPI wafer market are focusing on developing innovative solutions, such as next-generation epitaxial (EPI) wafers with enhanced uniformity and integration flexibility, to meet the increasing demand for high-performance semiconductors, efficient power devices, and advanced fabrication technologies. These new-generation EPI wafers offer superior control over thickness and doping compared to traditional wafers, enabling manufacturers to achieve greater device reliability, improved electrical performance, and easier integration into modern semiconductor systems. For instance, in September 2024, Coherent Corp., a U.S.-based semiconductor materials and wafer solutions provider, introduced its 200 mm silicon carbide (SiC) epitaxial wafers. These wafers deliver ultra-high thickness uniformity to ensure consistent device performance and feature precise doping uniformity to support next-generation, high-efficiency SiC power devices. Offered in 350 µm and 500 µm thickness options, they provide flexible integration for high-volume manufacturing. This launch strengthens Coherent’s position as a leader in advanced silicon epitaxial wafer technologies.

In January 2023, Veeco Instruments Inc., a U.S.-based provider of semiconductor process equipment including deposition, etch, and wafer-processing systems, acquired Epiluvac AB for approximately $30 million. Through this acquisition, Veeco sought to accelerate its entry into the fast-growing silicon carbide epitaxy equipment segment by incorporating Epiluvac’s chemical-vapor-deposition systems and expertise, thereby enhancing its technological capabilities and market position in silicon EPI wafer production. Epiluvac AB is a Sweden-based provider of chemical-vapor-deposition epitaxy systems for advanced silicon-carbide applications.
