Global Epitaxial Wafer Market to Grow at a CAGR of 12.30% during 2026-2035, Driven by the Rising Adoption of SiC Epi-Wafer in Electric and Autonomous Vehicles

The rising demand for silicon epitaxial wafers could be attributed to its characteristics like heightened flexibility. Silicon EPI wafers can be moulded into desired shapes and sizes for various applications, including the development of photoelectric cells, integrated circuits, and MEMS, among others for numerous industrial uses, such as automotive, consumer electronics, and healthcare. In addition, due to the expansion in the use of electro-optical components, widely found in telecommunications and display technologies, epitaxy is emerging as a significant technique to enhance the functionality of wafers. This is stimulating the market growth.  Furthermore, the industry growth has been augmented by epitaxial wafers used in the automotive sector. With the rise in electric vehicles and autonomous vehicle technology, epitaxial wafers find applications in navigation systems, infotainment systems, and collision detectors, among others. Hence, the global market for epitaxial wafers is expected to witness growth with increasing technological advancements in the coming years.

Showa Denko K.K. (TSE:4004), a global leader in the market for epitaxial wafers, in September 2021 announced that the company will be providing highly efficient SiC-power-semiconductor based power devices for the overall market to supply SiC epitaxial wafers for power semiconductors (SiC epi-wafers) to Toshiba (TYO: 6502). Toshiba is a leading company engaged in developing and commercialising numerous kinds of SiC-based power devices while adopting SiC epi-wafers. Sic epitaxial wafers produced by Showa Denka are marked with high performance and highly reliable characteristics, hence contributing to the rising adoption of SiC power semiconductors to save energy with minimal power loss and less heat generation. Such developments in the market are expected to boost the market growth.
